Hearing test method for adjusting a sound source volume

The present invention relates to a hearing test method by adjusting the size of a sound source, and more particularly, by adjusting the size of the sound source according to the selective frequency band and performing the verification of the subject by the sound source that can increase the accuracy and speed of the hearing test Hearing test method by adjusting the size of the.

In general, hearing, which is one of the sensory organs of the human body in human life, is a very important sensory organ, as well as visual perception.

Unlike other sensations, the hearing is a phenomenon in which the cognitive weakness gradually decreases with aging, and progresses slowly except for a sudden hearing loss, and often does not feel about a change in his / her hearing cognition. In addition, even if they are aware of hearing changes, they often miss early detection and early treatment because they do not have time to go to the hospital in busy daily life.

In particular, workplace noise is increasing due to recent industrial development and rapid changes in the industrial environment, and noise-induced hearing loss caused by this is increasing.

In addition, due to this, various mechanisms to block noise are developed and work environment is required to work in a better working environment. In general, when working for a long time in a noisy working environment, the human body's sensitivity to the noise level decreases due to the human body's environmental stress, which is accustomed to the noise generated in the workplace. .

These cognitive changes (hearing loss) of hearing are divided into acute hearing loss (abrupt hearing loss) that is rapidly decreased hearing and hearing loss which is gradually attenuated for some reason. Hearing attenuation, which proceeds very slowly, is often unrecognizable. In the case of sudden hearing loss that is rapidly deafening, early treatment through early detection is very important for the prognosis of the disease.

However, busy modern people often do not have time to go to the hospital, and by helping them to conduct a pure hearing test in a simple web environment, they can detect early hearing loss and give early warning to enable early treatment.

Also, if your hearing is slowly declining, you should visit your own hospital or clinic periodically to diagnose it early. You should be prepared and run the test all the time to know your hearing changes.

However, this method of hearing diagnosis has a very inconvenient disadvantage, such as the loss of time and the appointment of medical time when visiting a doctor or a clinic, and the need for expensive special equipment for accurate self-diagnosis. It is.

In order to solve the problems of the above-mentioned hearing diagnosis method, a hearing test method using the Internet and a recording medium (registration number: KR 10-345371) containing the program are registered.However, the hearing test method and the program using the Internet are registered. There is a problem that the recording medium containing the is less accurate.

In addition, the dedicated equipment is expensive, there is a problem that shows a different dB for each sound card and OS when using a computer.

On the other hand, the hearing measurement method using the frequency band can be largely divided into two.

First, the frequency prediction skipping method can perform high speed because it does not check the frequencies of all bands, but there is a problem that the accuracy is low.

Second, the method of checking all the frequency bands has a problem that it takes a lot of time to check the frequency of all bands from A to B as shown in FIG.

The present invention includes a device for directly applying the sound inside the ear, and to produce a decibel file for each operating system and sound card to automatically select the operating system and decibels and then adjust the volume of the output to increase the accuracy and speed of the hearing test It is to provide a hearing test method by adjusting the size of the sound source.

According to the present invention for solving the problems described above, the method for hearing test by adjusting the size of the sound source and the frequency random method comprises the steps of: (a) outputting the initial sound source output and the beep to the examinee through the beeper output unit; (b) confirming whether or not the test subject has been received; (c) when the examinee receives the tone in step (b), the tone output unit outputs a higher sound source output and a tone having a different frequency skipping a predetermined decibel; And (d) when the examinee does not receive the beeping sound in step (b), outputting a lower sound source output and a beeping sound of a different frequency skipping a predetermined decibel. do.

The hearing test method further includes (e) checking whether the different frequencies are the final frequencies of the range to be examined.

The hearing test method may further include the step (f) returning to the step (b) when the different frequencies are not frequencies in the range to be examined.

In the step (a), the initial frequency of the initial sound source output is characterized in that 40 decibels.

The present invention includes a device for directly applying the sound inside the ear, and when the operating system and sound card by decibel file is automatically selected and the operating system and decibels are automatically selected after adjusting the volume of the sound when inspecting all bands of frequency In comparison, speed improvements of 30% to 70% can be expected.

In addition, the present invention can simultaneously improve the disadvantages of the less accurate frequency prediction skipping method and all the time-consuming frequency checking method.

Preferred embodiments of the hearing inspection method and stereotactic fitting method using the frequency random method and the size of the sound source according to the present invention will be described with reference to FIGS. 1 to 13. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

Note that the term "skip" in the present invention means to output a sound source by selecting a specific frequency band from a frequency within a certain band throughout the specification.

Hereinafter, referring to FIGS. 1 and 2, the hearing test method skips the frequency bands of the hearing test method and the hearing test method according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, the conventional hearing test method has a disadvantage in that the test time is very long because all frequency bands between A and B of the horizontal axis are examined, but the hearing test method of the present invention crosses the frequency band. Since the output value is determined while running, there is an advantage that the hearing can be measured faster than the conventional hearing test method.

Hereinafter, with reference to Figure 3 briefly described the components required for the hearing test method according to an embodiment of the present invention.

The frequency output unit 110, the frequency converter 120, and the tone output unit 130 are included in the computing device 100. In addition, the output device 200 is a device that can receive a signal sound transmitted from the signal output unit 130, for example, an earphone, a headset, and the like.

The data storage unit 300 may select any one of eight sentences according to the examinee (adult or adolescent), select a job, and click the output button.

The stereotactic fitting unit 400 calculates a difference according to a signal-to-noise ratio (SNR) mixed with energy and noise for each data sentence of the data storage unit 300.

The fitting output unit 500 outputs the signal-to-noise ratio passed through the stereotactic fitting unit 400 as a percentage to display means such as a monitor.

A more detailed description of the hearing inspection method by controlling the size of the sound source and the frequency random method according to an embodiment of the present invention will be described later.

Hereinafter, referring to FIG. 4, the flow of a hearing test method through controlling the size of a sound source of the present invention will be described.

Initially, although not shown in FIG. 4, before the step S100, there is a preparation step of inputting an administrator ID and password and outputting an administrator information screen composed of a customer information screen, a hearing test screen, and a setting screen.

After the preparation step, the initial frequency and the sound source output is selected (S100).

Next, a signal sound is output to the selected sound source output at the selected frequency after step S100 (S110). The output signal is transmitted to the examinee through the output device 200 to confirm whether or not the reception (S120).

If the test subject receives the output tone in step S120, the sound source output is reduced (131).

After step S131, a new frequency band is selected by skipping to another frequency (S140). Also, it is checked whether or not the selected different frequency is the final frequency (S150). If the different frequency is the final frequency, the process ends. Otherwise, the process returns to step S120.

On the other hand, if the test subject does not receive the output signal in step S120 to increase the sound source output (136), and skips to another frequency to select a new frequency band (S140). Also, it is checked whether or not the selected different frequency is the final frequency (S150). If the different frequency is the final frequency, the process ends. Otherwise, the process returns to step S120.

Hereinafter, the first preparation step for the hearing test method according to an embodiment of the present invention with reference to Figures 5a to 6b in order as follows.

As shown in FIG. 5A, the initial screen of the hearing test program is divided into an automatic mode and a manual mode. In the manual mode, an administrator ID and a password can be input and used. In one embodiment of the present invention, the initial administrator ID is set to "kwadmin", the current password is temporarily assigned 1111, and thus "kwadmin" may add an administrator.

Next, when the administrator information screen of the hearing test program is logged in at the initial screen of FIG. 5A, the administrator information screen as shown in FIG. 5B appears. In the case of "kwadmin", there is a button to add an administrator. At the top is a tab that takes you to different screens, each of which consists of customer information, hearing tests, and settings. These settings are only visible to "kwadmin" and are not visible to normal administrators.

The tab of "MIC ON" is the microphone output button, and when the button is clicked, the person performing the test can deliver the voice to the customer through the microphone. If you press the button, a new microphone On / Off window appears, and you can operate it by clicking the microphone in the window.

The Volume Meter shows the output of all sounds in real time, including voice files. When the sound is output, it is displayed in the form of a green bar to visually determine whether or not the sound is output.

Next, the customer information screen of the hearing test program shown in FIG. 6A is divided into a top and a bottom. The upper part is a window for managing individual customers, and the lower part is a window showing various inspection information of the selected customer. If you want to delete or modify each customer's information, click the customer and then right-click to delete and modify the information. Deletion can be done with the Del key on the keyboard and editing can be done with the Ctrl + M buttons.

You can start a new inspection by clicking the Start Selective Inspection button in the middle. If you want to add a new customer, click the Add New Customer button. New customer can be added in the following window.

Next, in the new customer information screen of the hearing test program shown in FIG. 6B, the new customer information may enter a name, social security number (not required), gender, contact information, address, and other matters. It is entered automatically. The patient ID is used for automatic identification to represent uniqueness and prevent confusion. The ID configuration method consists of year, month, day, and random 6 digits to prevent overlapping.

Hereinafter, the hearing test method according to an embodiment of the present invention will be described in detail with reference to FIGS. 7A to 9D.

According to an embodiment of the present invention, a method for checking a hearing by adjusting a frequency random method and a size of a sound source may include (a) outputting an initial sound source and a signal tone to the examinee through the tone output unit 130, (b) (C) when the examinee receives a beep, the beep output unit 130 outputs a higher sound source output and a beep of different frequencies skipping a predetermined decibel, and (d) When not receiving a beep, the beep output unit 130 includes outputting a lower sound source output and a beep of different frequencies skipping a predetermined decibel.

(a) In the stage in which the initial sound source output and the signal sound are output to the examinee through the signal sound output unit 130, a hearing test screen as shown in FIG. 7A appears, and the right ear is first selected and measured.

At this time, the hearing test window selects the right ear and the left ear, and sets the right ear first. The middle graph shows the change in real time.

Next, FIG. 7B illustrates a hearing test screen on which a sound of a hearing test program is output. In the middle of the hearing screen, there is a frequency-specific selection and numeric control buttons, and a window for direct entry. The frequency band at this time is output through the frequency output unit 110. You can also change the decibel by pressing the up and down arrows on the keyboard to easily change the numbers with the keyboard, and the left and right arrows to select the next and previous frequencies.

(b) In the step of checking whether the examinee is received, a hearing test screen in which a beep is output to the left ear of the hearing test program is illustrated as shown in FIG. 7C. First, select the frequency and the decibel and press the "Stimulus" button to output a beep. The beep is transmitted to the examinee's ear through the output device 200. When the customer indicates that the sound is heard, the left side is displayed. Clicking on the "Marking" button will move the graph directly to that frequency, and if you press an external switch that has been developed, the circular button at the bottom will be red, and the "Marking" button will be pressed. It performs the same operation as that, and at the bottom, the tester can directly input the result and the specifics.

In addition, the audio output screen through the microphone of the hearing test program is shown in FIG. 8A as an additional method for giving a testee a beep. Voice output via a microphone was also implemented to allow the subject to signal the customer in the soundproof room. Click the "MIC ON" button at the top, press the microphone output in the newly appeared microphone control window, and when the tester talks to the microphone, the time delay (stabilization time) of about 0.3 ~ 0.5 seconds through the output device 200 It is delivered to the examinee's ear. At this time, the output signal is displayed on the volumetric meter and can be distinguished by the naked eye.

Next, FIG. 8B shows a setting screen for outputting a voice through a microphone of a hearing test program. Here, the setting screen allows editing of a database of stereotactic automatic hearing and stereotactic fitting test in one screen. As a result, it is expected that there will be a problem in system stability if the customer adds or changes the sound source file directly due to the different settings depending on the system. For this reason, it is more stable to change the settings by changing the settings in Gwangwoo Medics and copying the sound files and database files to a specific folder.

FIG. 8C is a setting basic screen illustrating a screen proceeding to the next step in FIG. 8B. You can load database files from the current program, add files to it, or delete visible lists. You can also adjust the system volume manually. After adding a sound source or modifying the data, you can edit the sound source database by pressing the "Replace Sound" button.

Next, (c) when the examinee receives a beep, the beep output unit 130 outputs a higher sound source output and a beep of different frequencies skipping a predetermined decibel, and (d) the examinee does not receive a beep. In the case where the beep output unit 130 outputs a lower sound source output and a beep of different frequencies skipping a predetermined decibel as follows.

The automatic inspection mode of FIGS. 9A to 9D immediately operates when the "start inspection" button is clicked on the initial screen. First of all, a window for selecting general scan and high-speed scan appears, and if you click the corresponding button, you will be directed to the scan screen.

To start the scan, click the "Start Scan" button on the left to start the scan. The time until the program start is displayed in the center, and after 5 seconds, the message changes to "Inspecting". When the customer hears the sound, they can click the "sound" button or click the external USB button to activate it.

When the examinee receives a beeping sound, (e) checking whether different frequencies are the final frequencies of the range to be examined and ending when the final frequencies are correct.

On the other hand, if the subject does not receive a beep (f) if the different frequency is not the frequency of the range to be examined, the process returns to step (b). After returning to step (b), the initial frequency is converted to a different frequency through the frequency converter 120, and a series of processes are performed according to the flowchart shown in FIG.

As described above, when the final frequency is confirmed, an automatic test result screen of the hearing test program is output as shown in FIG. 10.

FIG. 10 illustrates a window for outputting an experimental result. In the case of a manual test, information of a corresponding patient is automatically displayed, and in the case of an automatic test, a manual input can be directly inputted or output as it is and can be written by hand. In case of direct input, the resident registration number is automatically entered. After completing the form, click "Print Test Result" at the bottom to print the result.
