Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, embodiments of the present invention illustrated below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

First, the present invention is a PC-based pure sound hearing test system of a client / server model in which one tester can simultaneously perform hearing test of several test subjects, and a plurality of test terminals are connected to a wired / wireless communication network such as a local area network (LAN). LAN has a structure connected to the server or terminal for the examiner, and the test progress of each subject is displayed on the screen of the server or terminal for the examiner in real time.

In addition, according to the present invention, by providing the function of performing the re-test according to the use of the narrow-band shielding sound, the effective masking (effect masking) range, there is an effect that the accuracy of the shielding and inspection results can be improved.

1 is an overall configuration diagram for explaining a pure sound hearing test system capable of simultaneously testing a plurality of subjects according to an embodiment of the present invention, Figure 2 is a detailed description of a test subject terminal applied to an embodiment of the present invention It is a block diagram for the following.

1 and 2, the pure-sound hearing test system capable of simultaneously testing a plurality of subjects according to an embodiment of the present invention includes a plurality of subject terminals 100-1 to 100-n, It is composed of a server for the examiner 300 is connected to each of the examinee terminal (100-1 to 100-n) through the / wireless communication network (200).

Here, the plurality of examinee terminals 100-1 to 100-n are equipped with the examinee program module 190 so that the examinee can perform at least one of pure air hearing tests among the airway hearing test, bone hearing test or shield test. It performs the function.

As shown in FIG. 2, the plurality of examinee terminals 100-1 to 100-n are large, the display unit 110, the sound generation circuit unit 120, the output unit 130, the input unit 140, and airway hearing. The inspection unit 150, the bone hearing test unit 160, the shielding inspection unit 170 and the controller 180 and the like.

Here, the display unit 110 displays a guide or a test result for the use procedure. In one embodiment of the present invention, a monitor is used. However, instead of using a monitor as described above, the guide is printed on one side of the device and a plurality of bulbs are installed on one side of the print door to guide the light to be guided according to the procedure, and the liquid crystal is provided on one side of the device. It is also possible to configure to show.

The sound generating circuit unit 120 generates a sound according to the control signal when the control signal is received from the control unit 180. The control signal is input including the frequency and intensity of the sound to be generated, and which of the left and right ears to generate.

In addition, the sound generating circuit unit 120 generates a sound having the frequency and intensity accordingly and outputs it as an electrical signal. The sound generating circuit unit 120 is preferably to use a commercial sound card for commercially available on the market.

The output unit 130 may include, for example, a headphone and a bone oscillator. The headphone converts the sound into sound when an electrical signal is transmitted from the sound generating circuit unit 120. The bone conduction vibrator converts the signal into a vibration and transmits the vibration toward the skull when the electrical signal is transmitted from the sound generating circuit unit 120 in the state of being mounted on the rear lip protrusion of the ear. On the other hand, it is well known to those skilled in the art that the headphone and the bone oscillator vibrate to generate sound in accordance with the electrical signal generated in the sound generating circuit unit 120, so a detailed description thereof will be omitted.

The input unit 140 is provided so that the subject can hear that the sound is heard on the pure sound hearing inspection apparatus when the subject hears the sound through the output unit 130. In an embodiment of the present invention, the input unit 140 is preferably, for example, a computer keyboard, but is not limited thereto. For example, the input unit 140 may use a switch or a touch screen.

Airway hearing test unit 150 to generate a pure sound in the headphones worn by the subject to determine whether the user can hear the pure sound delivered to the eardrum through the ear canal to obtain a hearing threshold. To this end, the airway hearing inspection unit 150 generates a control signal to adjust the sound pressure of the pure sound generated according to the reaction of the subject through the input unit 140.

For example, if the user cannot hear the sound of 40 decibels, the control signal is output to generate a sound pressure increased to 45 decibels, and when the user hears the sound of 40 decibels, the sound pressure is reduced to 35 decibels. Will output a signal.

In addition, the airway hearing test unit 150 is to examine each of the left and right ears. First, the airway hearing test unit 150 generates a pure sound of a constant frequency, but initially provides a constant sound pressure (40 decibels) and increases or decreases at intervals of 5 decibels according to the response, and the minimum sound pressure that the user can hear becomes the hearing threshold. . The test is performed according to various frequencies to obtain a hearing threshold for each frequency.

The bone hearing test unit 160 checks the user's hearing for the sound transmitted through the skull. The airway hearing test is difficult to accurately test if there is a problem in the outer ear and middle ear, such as a subject suffering from lesions of the outer ear or otitis media. Therefore, in this case it is necessary to test hearing using vibrations transmitted through the skull.

The bone hearing test unit 160 transmits an electrical signal to the bone conduction vibrating body instead of a headphone to generate a pure sound by vibration to obtain a bone hearing threshold of the ear. Bone hearing test unit 160 is the same process as the airway hearing test unit 150, so the detailed description will be omitted.

The shielding inspection unit 170 checks the hearing by transmitting a pure sound to the ear to be measured while listening to noise of a headphone inserted into one ear. This is to prevent the hearing because the hearing of both ears is much different from the sound through the ear canal instead of the sound is transmitted through the skull to the good ear.

In general, the shielding test unit 170 has a difference in the air conduction threshold of each ear when the difference in the air conduction threshold of both ears is greater than the separation between each frequency, or the hearing conduction threshold of the ear having a good hearing and the hearing conduction threshold of the ear having a bad hearing are each frequency. This is done if there is a difference in abnormal airway decay abnormalities, and in the case of a bone conduction hearing test, the difference between the air conduction threshold and the bone conduction threshold in the same ear is 15 decibels or more. Here, the good ear means the ear that is relatively low in the air conduction threshold of both ears, and can hear the small sound well, and the bad ear means the ear that cannot hear the small sound well because of the high air conduction threshold.

When the shielding inspection unit 170 is shielded against bone hearing, it determines the ear to wear the headphone and the ear to which the bone conduction vibrator is attached, and then outputs a control signal to display it on the display unit 110. In addition, the shielding inspection unit 170 generates a control signal to increase the sound pressure of the noise when the subject hears the pure sound, and increases the pure sound when the subject does not hear the sound.

The controller 180 is connected to the display unit 110, the sound generating circuit unit 120, the input unit 140, the airway hearing test unit 150, the bone conduction hearing test unit 160, and the shielding test unit 170 to control each of them. do. The control unit 180 receives the control signal for the frequency and sound pressure is transmitted to the sound generating circuit unit 120 to perform the test in the airway hearing test unit 150, bone conduction hearing test unit 160 and shielding test unit 170 It is converted into a control signal that can be received and transmitted.

This means that the sound generating circuit unit 120 uses a sound card that is commercially available in the market, and thus the control unit 180 converts and transmits the control signal according to each sound card. In addition, the controller 180 transmits a control signal to the display unit 110 as the inspection proceeds so as to display a guide of a necessary procedure. For example, in the screening test, the head of the headphone and the ear to which the bone oscillator is to be attached are displayed on the monitor screen so that the subject can be properly fitted.

In addition, the controller 180 receives the signal input from the input unit 140 and transmits it to the airway hearing test unit 150, bone conduction hearing test unit 160 and shielding test unit 170. Herein, the controller 180 further includes a test result storage unit 182 for storing test results to display the type and degree of hearing loss and to check the test result at any time.

In addition, the controller 180 stores information about the headphones and the bone conduction vibrations of the sound generating circuit unit 120 and the output unit 130. Since the characteristics of the sound generating circuit unit 120, the headphone, and the bone oscillation body vary depending on the manufacturer or model, it is difficult to generate accurate sound with a uniform control signal. You must store the properties separately. To this end, it is necessary to check the characteristics of the various sound generating circuit unit 120, headphones, bone conduction vibration body in advance.

That is, the controller 180 measures an electrical signal, a sound, or a vibration that is output while increasing or decreasing the sound pressure for each frequency to determine a value to be corrected for each frequency for each device, and stores it in the characteristic DB 184 and outputs the controller. The 180 finds a correction value for the corresponding model and applies the correction to the correction value.

For example, when the connected headphones generate a signal of 35 decibels at 1000 Hz, when the sound before the correction is 30 decibels, the controller 180 generates a control signal to generate a 35 decibel signal to the sound generating circuit. The signal output from the headphone is 35 decibels.

The plurality of examinee terminals 100-1 to 100-n configured as described above or the inspector terminal 500 to be described later are generally computers, such as a desktop PC and a notebook PC, but are not limited thereto. It may be any kind of wired / wireless communication device capable of using the bidirectional transmission / reception service by accessing the server 300 for the inspector through the wireless communication network 200.

For example, the test terminal 100-1 to 100-n or the test terminal 500 to be described later is a cellular phone (PCS): PCS (personal phone) to communicate through a wireless Internet or a portable Internet It includes mobile terminals such as Communications Services phone (SMS) and synchronous / asynchronous IMT-2000 (International Mobile Telecommunication-2000). In addition, Palm Personal Computer (PDA), Personal Digital Assistant (PDA), Smart Phone ) Can be a generic term for all wired / wireless home appliances / communication devices that have a user interface for accessing the server 300 for the inspector, such as a WAP phone, a wireless application protocol phone, and a mobile play-station. have.

Hereinafter, with reference to the accompanying Figure 2 will be described in detail the operation and effect of the terminal for a subject applied to an embodiment of the present invention.

First, the type of the sound generating circuit unit 120 mounted on the examinee terminals 100-1 to 100-n of the present invention is input using a keyboard with reference to a screen displayed on the display unit 110. In addition, the headphone and the bone oscillation body connected to the sound generating circuit unit 120 also input the manufacturer and model so that the controller 180 can correct it.

On the other hand, when the subject requests a pure hearing test, the controller 180 transmits a control signal for the airway hearing test unit 150 to proceed with the procedure. The airway hearing test unit 150 displays a guide to wear headphones on the display unit 110 through the controller 180, and when the examinee presses the enter key after wearing the headphones according to the display, the input signal input through the keyboard. Is delivered to the airway hearing test unit 150 through the control unit 180 to start the hearing test.

At this time, the airway hearing test unit 150 is to first select the ear to the subject and then examine the ear from the side selected by the subject. The test method first generates a pure tone of 1000 Hz and 40 decibels and outputs it to the ear selected by the examinee. When the testee hears the sound and presses the predetermined button, the tester descends by 5 decibel intervals, and if it is not heard (when there is no button input for a predetermined time), the tester raises the test by 5 decibel intervals. In order to obtain the threshold, the test is repeated three times and the threshold value is determined when the response of the test subject is the same two or more times. First, the test is performed at 1000 Hz, then measured at a high frequency range of 2000 Hz, 3000 Hz, 4000 Hz, and 8000 Hz, and the threshold value of 1000 Hz is obtained again. At this time, when the threshold value of 1000 Hz differs by more than 10 decibels from the beginning, the measurement of the high range is performed again. In the case of 5 decibels or less, the low frequencies are measured in the order of 500 Hz, 250 Hz, and 125 Hz.

Perform the same procedure on the opposite ear to obtain the airway hearing threshold of both ears. After that, when the difference between the airway conduction thresholds on both sides differs from the air conduction conduction attenuation abnormalities for each frequency, the controller 180 calls the shielding inspection unit 170. The shielding test unit 170 first to listen to the noise on the good ear to listen to the pure sound to the bad ear and increase or decrease the sound pressure of the noise or pure sound in accordance with the reaction of the examinee to examine the hearing.

After the test as described above, a subject who is suspected of hearing loss or who suffers from otitis media performs a bone hearing test. The bone hearing test is a test to detect that the vibration is transmitted through the skull after receiving the vibration through the bone conduction vibrating body attached to the back of the ear instead of headphones. In this case, the bone hearing test measures only the frequency from 250 Hz to 4000 Hz. The test process is the same as the process for obtaining the airway hearing threshold, so a detailed description thereof will be omitted.

After that, if the difference between the air conduction threshold and the bone conduction threshold in the measured test ear is 15 decibels or more, the controller 180 calls the shield test unit 170 and the shield test unit 170 attaches the bone conduction body to the ear to be measured. After the headphones are worn on the opposite side of the ear, noise is transmitted to the headphones, and a pure tone is transmitted to the bone conduction body to perform a hearing test. After that, the measured result is displayed on the screen of the display unit 110 and can be output through a connected printer if necessary.

When the test is made as described above, it is possible to accurately obtain the airway hearing threshold and the bone hearing threshold, which helps in the prevention and early detection of hearing loss without the help of a doctor or professional audiologist.

The wired / wireless communication network 200 may be formed of, for example, the Internet or a local area network (LAN). At this time, the Internet is a TCP / IP protocol and a number of services existing in the upper layer, that is, Hyper Text Transfer Protocol (HTTP), Telnet, File Transfer Protocol (FTP), Domain Name System (DNS), and Simple Mail Transfer Protocol (SMTP). ), A worldwide open computer network structure that provides Simple Network Management Protocol (SNMP), Network File Service (NFS), Network Information Service (NIS), and the like. It provides an environment that allows any subject to be connected to the server 300 for the inspector. The Internet may be a wired or wireless internet, or may be a core network integrated with a wired public network, a wireless mobile communication network, or a portable internet.

In addition, the test server 300 is remotely connected through each test terminal 100-1 to 100-n and a wired / wireless communication network 200, the test program module 350 is mounted to each test subject The mobile terminal 100-1 to 100-n receive the test data of the pure audio hearing test and perform the function of monitoring the test status information and the test result of each test subject in real time.

The inspector server 300 receives a specific event message related to the pure sound hearing test from each of the examinee terminals 100-1 to 100-n and controls the operation of the corresponding guidance message or the corresponding pure sound hearing test. It may be transmitted to the examinee terminal (100-1 to 100-n).

In addition, the hearing test DB (400) connected to the test server 300, which stores and manages the database of the pure audio hearing test data examined by each testee terminal (100-1 to 100-n) for each test subject. It may be provided.

Furthermore, the pure sound hearing test data connected to the tester server 300 through the wired / wireless communication network 200 and connected to the tester server 300 and transmitted from each testee terminal 100-1 to 100-n. In order to monitor the test status information and test results of each subject in real time, or receive a pure sound hearing test data and a specific event message transmitted from each of the terminal (100-1 to 100-n) for the guidance message corresponding to this The tester terminal 500 may further include a signal for controlling the progress operation of the pure sound hearing test to the tester terminals 100-1 to 100-n through the test server 300.

Each of the test terminal 100-1 to 100-n configured as described above and the test server 300 or the test terminal 500 may be made to exchange in real time a specific event message related to the pure sound hearing test. For example, the real-time message exchange between each of the examinee terminals 100-1 through 100-n and the examiner server 300 or the examiner terminal 500 may be based on, for example, a simple object access protocol based on XML (Extensible Markup Language). Access Protocol, SOAP) is preferable.

Each testee terminal (100-1 to 100-n) applied to an embodiment of the present invention configured as described above is running the test program module 190 for the hearing test, the test server 300 or The tester program module 350 is performed on the tester terminal 500.

That is, each test terminal 100-1 to 100-n is configured to operate while exchanging a message with the test server 300 directly. In such a configuration, the test-related database, that is, the hearing test DB 400 should always be located in the tester server 300. The hearing test DB 400 is present in the server 300 for the tester, and each test terminal 100-1 to 100-n exchanges messages with the test server 300.

In addition, the tester terminal 500 may also implement a configuration of exchanging messages by connecting to the tester server 300. That is, the message transmitted from each of the examinee terminals 100-1 to 100-n is delivered to the inspector terminal 500 via the inspector server 300.

On the other hand, a function that must be included in each terminal 100-1 to 100-n is essential to generate a test sound, and if the hearing difference between both ears is greater than a certain criterion, the test ear is not tested while the test sound is heard. The creation of automatic shielding to provide shielding for the ear that is not present, the ability to calibrate for accurate sound, and audiograms that show the test results graphically and data management to store and manage the test results are the most essential functions. .

Each of the examinee terminals 100-1 to 100-n generates pure sound, for example, in software (or hardware). Generates and plays back data in 24-bit PCM format, sampled at 44100 times / second in real time as needed. This can be implemented using waveOut libraries to play sounds using the Windows multimedia interface.

On the other hand, if the hearing difference between the two ears is greater than the attenuation attenuation, when hearing the ear with the larger hearing loss, the test sound is heard by the opposite side due to the cross-hearing can not be accurate hearing measurement. To prevent this, a shielding sound is used. In the present invention, it is preferable to generate and use a narrowband shielding sound defined in ISO 389-4. To this end, a method of converting wideband noise generated by a Gaussian random number generator into narrowband noise using a second order IIR bandpass filter may be used.

On the other hand, for the determination of thresholds, a modified ascension method recognized by the Korea Occupational Safety and Health Agency and the British Society of Audiology as a standard hearing test method may be used. In the ascension method, the initial pure tone intensity starts at 30 decibels and continues to increase by 20 decibels until the subject responds, and then starts at the level at which the subject first reacts.

After the subject's first reaction, the test is continued at 10 decibels until it stops responding again. At no intensity, increase 5 decibels until there is a reaction. This procedure is repeated three or more times to determine the minimum audio threshold if there is a response of 50% or more at the same negative intensity. From the second measurement frequency (2KHz), the threshold of the previously tested frequency starts at 30 decibels high, and the process of 10 decibels falling and 5 decibels rising is performed in the same manner to determine the threshold. Even in this case, it is increased by 5 decibels above 80 decibels.

The plateau method can be used as a method for determining the threshold in the shielded state. The horizontal shielding method is a method of determining the threshold value by finding a shield amount that is horizontal without increasing the threshold value of the test ear even when noise is increased while the test sound of the test ear is fixed.

As described above, in the present invention, a system capable of performing a hearing test by the examinee and monitoring a state of a plurality of examinees and having a one-to-one correspondence can be implemented. In order to remotely monitor the test status information and the test result of the test subject, for example, a simple object access protocol (SOAP) may be used to implement a function that enables one-to-one correspondence with the test subject.

The present invention, which is designed as a server / client structure, may be designed as a client program that allows a tester to test himself / herself, and a tester management program that may monitor a testee's condition in real time using data transmitted from a server.

Next, each examinee terminal (100-1 to 100-n) transmits the pure sound hearing test information and the login information (Login) of the examinee performed in step S100 to the examiner server 300 (S200).

Subsequently, the inspector receives the log-in and net sound test information of the examinee transmitted in step S200 and monitors the test state information and the test result of each examinee in real time.

In addition, by receiving the log-in and net sound test information of the test subject transmitted in step S200, the process of storing and managing the database for each subject in a separate hearing test DB 400 connected to the test server 300 is further stored. It may include.

Furthermore, in step S100, each test subject terminal 100-1 to 100-n transmits an event message requesting help to the tester server 300 when a problem occurs during the pure-tone hearing test, or for a predetermined time. When the pure sound hearing test is not performed, the method may further include transmitting a test abnormality event message to the server 300 for the inspector.

In addition, in step S300, the inspector server 300 is connected to the inspector server 300 so that the inspector can recognize when receiving a specific event message from each of the examinee terminals 100-1 to 100-n. It may further include the step of displaying on the screen of, or transmitting a guidance message corresponding to the specific event message or a signal for controlling the progress operation of the pure sound hearing test to the examinee terminal (100-1 to 100-n). .

Meanwhile, messages are exchanged in real time between each of the examinee terminals 100-1 to 100-n and the inspector server 300, and the message exchange uses XML-based Simple Object Access Protocol (SOAP). It is available.

In this case, the simple object access protocol (SOAP) is a multipurpose, simple and lightweight message exchange protocol. This simple object access protocol (SOAP) is based on XML, and is characterized by platform and programming language independence. 1.2 is the latest version and offers some form of message pattern, but the remote function call pattern is the most widely used.

In addition, although there are many software that implement the SOAP function, it can be implemented using gSOAP provided as open software regardless of the Windows operating system and other operating systems. GSOAP, which provides a C / C ++ interface, is easy to use because it hides the details of the protocol from the user. It also has the advantage of not only needing additional class libraries but also excellent performance.
