Detailed Description
The following detailed description of a preferred embodiment of the invention is provided in conjunction with the accompanying drawings.
Fig. 1 is a block diagram of a device for simulating hearing correction according to a first embodiment of the present invention. As shown in the drawings, the present invention provides a device (hereinafter referred to as "simulation device") 1 for simulating hearing correction, which can compensate the original audio signal to generate a compensation audio signal with a simulated hearing correction effect, so that a user (e.g., a hearing-impaired patient) can experience a corrected hearing status.
The simulation apparatus 1 of the present invention mainly comprises a storage device 11 (such as a hard disk, a solid state hard disk, a RAM, a ROM, an EEPROM, a Flash Memory or any combination thereof) for storing data, an audio output device 12 (such as an earphone or a speaker) for playing audio, and a processing device 10 (such as a microprocessor or a central processing unit) electrically connected to the above devices for controlling the simulation apparatus 1.
Specifically, the storage device 11 can store hearing data corresponding to the current user and preset original audio (e.g. audio of a group of voices). The hearing data records the hearing test result of the user (such as the hearing ability of the user for each frequency or the hearing impaired frequency of the user). The processing device 10 may identify an impaired frequency of the user according to the hearing data, and perform a volume compensation process on the original audio signal according to the identified impaired frequency to generate a compensated audio signal. Then, the processing device 10 can control the audio output device 12 to play the generated compensation audio.
Therefore, the invention can customize the audio of the simulated hearing correction aiming at the user, and can enable the user to directly obtain the hearing feeling through the approximate hearing correction, thereby improving the willingness of the user to further carry out the hearing correction.
In one embodiment, the user first receives a hearing test to obtain the hearing data. The aforementioned obtaining of hearing data through hearing test is a common technique in the art, and is not described herein again.
In an embodiment, the simulation apparatus 1 further includes an audio input device 13 (e.g. a microphone) electrically connected to the processing device 10 and configured to sense the environmental audio.
In an embodiment, the simulation apparatus 1 further includes a human-machine interface 14 (such as a keypad, a mouse, a touch screen, or any combination of the aforementioned input/output devices) electrically connected to the processing device 10 and configured to receive user operations and provide information.
Please refer to fig. 2, which is a schematic diagram of a device for simulating hearing correction according to an embodiment of the present invention. As shown in the figure, in the present embodiment, the body of the device for simulating hearing correction (hereinafter referred to as a simulation device) 2 is a smart phone (which may be replaced by a tablet computer, a notebook computer or a personal computer, without limitation), and includes a human-machine interface 24 (in the present embodiment, a touch screen), a first audio output device 220 (in the present embodiment, a built-in receiver), and a first audio input device 230 (in the present embodiment, a built-in microphone).
In the present embodiment, the user can operate the human-machine interface 24 to perform a hearing test to generate hearing data. Then, the simulation device 2 can generate the compensation audio according to the hearing data and the original audio, and output the compensation audio through the first audio output device 220 to make the user listen to the audio corrected by the simulated hearing.
In an embodiment, the simulation apparatus 2 may sense the environmental audio signal as the original audio signal through the first audio input device 230, perform the compensation process on the original audio signal according to the hearing data, and output the compensated audio signal through the first audio output device 220 in real time. Through the real-time audio compensation, the simulation device 2 enables the user to experience the simulation effect of wearing the hearing aid, thereby improving the willingness of the user to perform hearing correction.
In one embodiment, the time difference between the sensing time of the first audio input device 230 sensing the original audio and the playing time of the first audio output device 220 playing the compensation audio is not greater than 50 milliseconds. The invention can provide better simulation effect of the hearing aid and improve user experience by reducing the delay between audio input and output.
In one embodiment, the simulation apparatus 2 is externally connected with an audio output device and/or an audio input device. Specifically, the simulation apparatus 2 may include a second audio output device 221 (in this example, an external earphone) and a second audio input device 231 (in this example, an external microphone). The simulation apparatus 2 can play the audio through the second audio output device 221 and sense the audio through the second audio input device 231.
It should be noted that, in general, the built-in first audio output device 220 and the built-in first audio input device 230 generally have poor sound reception capability (e.g., a narrow frequency range to be sensed, a weak received sound intensity or more noise) and poor playing capability (e.g., a narrow frequency range to be played, a low maximum output power or a poor sound quality), which may reduce the user experience.
The invention selects the external second audio input device 221 and the external second audio input device 231 with better receiving and playing capabilities to receive and play the audio through the external scheme, thereby improving the quality of the received original audio and the played compensation audio and further improving the user experience.
Fig. 3 is a schematic diagram of a processing apparatus according to an embodiment of the invention. In the present embodiment, the processing device 10 may include the following functional modules for implementing different functions.
1. The analysis module 30 is configured to analyze the hearing data to identify one or more hearing loss frequencies of the corresponding user.
2. The compensation module 31 is configured to compensate the volume of the hearing loss frequency of the original audio signal to generate a compensated audio signal.
3. The output control module 32 is used for controlling the audio output device 12 to play the audio according to the playing setting (or the adjusted playing setting).
4. The input control module 33 is used for controlling the audio input device 13 to sense the environmental audio.
5. The interface control module 34 is configured to control the human-machine interface 14 to receive user operations and generate corresponding data, and control the human-machine interface 14 to output information.
6. The hearing data generating module 35 is configured to generate hearing data based on feedback operation of the user.
7. The calibration module 36 is configured to adjust the playback setting of the audio output device 12 according to a difference between the output calibration audio and the input calibration audio.
The functional modules can be hardware modules or software modules. When the functional modules are hardware modules, they can be implemented as circuit modules (such as electronic circuits, integrated circuits, or digital circuits).
When the aforementioned functional modules are software modules, they can be implemented by a computer program (e.g., an application program or firmware). Further, the storage device 11 may include a non-transitory computer readable recording medium storing a plurality of computer programs, each of the plurality of computer programs corresponding to one of the plurality of function modules. Each computer program has computer executable code recorded thereon. Thus, after the processing device 10 executes the computer program corresponding to each functional module, the simulation apparatus 1 can be controlled to realize the functions corresponding to each functional module.
Please refer to fig. 4, which is a flowchart illustrating a method for calibrating a hearing ability according to an embodiment of the present invention. The method of simulating hearing correction (hereinafter referred to as simulation method) according to the embodiments of the present invention can be applied to the simulation device 1 or the simulation device 2 shown in fig. 1 to 3 (described later as being applied to the simulation device 1). The simulation method of the present embodiment includes the following steps.
Step S10: the processing device 10 obtains hearing data corresponding to the user from the storage device 11.
In one embodiment, the hearing data is pre-input by the user (or the operator of the simulation apparatus 1) and stored in the storage device 11.
In one embodiment, the processing device 10 may generate the hearing data based on the interaction between the user and the simulation apparatus 1 in the hearing test (e.g., feedback information input by the user via the human-machine interface 14).
Step S11: the processing device 10 performs an analysis process on the read hearing data via the analysis module 30 to identify a corresponding hearing loss frequency (i.e., the hearing loss frequency of the user).
In one embodiment, the hearing data records a current user's sensible volume for each frequency, and the sensible volume is a minimum volume that the current user (e.g., hearing impaired patient) can clearly hear at each frequency (the minimum volume can be obtained by hearing test). The storage device 11 stores the threshold volume of each frequency, which is the minimum volume (e.g. 25 db) clearly audible at each frequency for a general person (e.g. a person with normal hearing). The processing device 10 compares the sensible volume with the threshold volume, and determines that the sensible volume is an audible loss frequency when the sensible volume is greater than the threshold volume (i.e. the current user has worse hearing than the average person), and determines that the sensible volume is not greater than the threshold volume.
Step S12: the processing device 10 obtains the original audio signal. In one embodiment, the original audio is pre-stored in the storage device 11.
In one embodiment, the processing device 10 can control the audio input device 13 to sense environmental audio (such as speech generated by conversation of other people) via the input control module 33 to generate the original audio.
Step S13: the processing device 10 performs compensation processing on the volume of the hearing loss frequency of the original audio signal through the compensation module 31 to generate a compensated audio signal.
In one embodiment, in the compensation process, the processing device 10 increases the volume of each hearing loss frequency of the original audio signal to a sensible volume not less than the same frequency.
Step S14: the processing device 10 controls the audio output device 12 to play the compensation audio through the output control module 32.
Since the played compensation audio has been compensated for the volume of the hearing loss frequency of the hearing-impaired user, the user can clearly listen to all the contents of the played compensation audio, and can obtain the experience like hearing correction, thereby improving the willingness of the user to perform hearing correction.
Referring to fig. 4 and 5, fig. 5 is a flowchart of acquiring hearing data according to an embodiment of the invention. The hearing data of the present embodiment is generated by performing a hearing test on a user. Compared to the simulation method shown in fig. 4, the step S10 of the simulation method of the present embodiment includes the following steps for performing hearing tests.
Step S20: the processing device 10 controls the audio output device 12 to play the plurality of hearing test audio signals in turn through the output control module 32.
In an embodiment, the storage device 11 stores a plurality of hearing test audio signals in advance, and each hearing test audio signal corresponds to a different frequency. The processing device 10 can control the audio playing device 12 to play the plurality of hearing test audio signals in turn through the output control module 32.
In an embodiment, during the playing of the plurality of hearing test audio signals, the processing device 10 may control the human-machine interface 14 to display corresponding questionnaire information (first questionnaire information, such as inquiring whether the user hears each hearing test audio signal or understands the voice content corresponding to the hearing test audio signal) through the interface control module 34.
Step S21: the processing device 10 can control the human-machine interface 14 to receive a feedback operation (a first feedback operation) input by the user based on each hearing test audio through the interface control module 34 during the playing of the plurality of hearing test audio.
In an embodiment, the first feedback operation based on each hearing test audio is to evaluate whether the user clearly hears each hearing test audio.
Step S22: the processing device 10 generates hearing data according to all the first feedback operations and the frequencies corresponding to the hearing test audio signals through the hearing data generating module 35.
Therefore, the invention can effectively carry out complete detection on the hearing ability of the user and generate corresponding hearing data.
Fig. 6 is a flowchart illustrating an apparatus calibration according to an embodiment of the invention. The present embodiment further provides an apparatus calibration function, which can calibrate the audio played by the audio output device 12 and the audio sensed by the audio input device 13, so as to greatly reduce the difference between the played audio and the sensed audio, thereby improving the accuracy of hearing detection, improving the accuracy of compensation processing, and improving the sound quality of the sensed original audio or the sensed compensated audio.
Specifically, in the present embodiment, the storage device 11 stores output calibration audio, play setting and/or reception setting (such as volume correction parameter, frequency correction parameter or other audio correction parameters). Before the first use of the simulation apparatus 1, the processing device 10 may first perform an apparatus calibration function to adjust the playback setting and/or the reception setting, so as to greatly reduce the error between the input audio and the output audio. The simulation method of the present embodiment further includes the following steps to perform the device calibration function.
Step S30: the processing device 10 loads and outputs the calibration audio and the playback setting from the storage device 11, and controls the audio output device 12 to play the calibration audio through the output control module 32 according to the playback setting.
Step S31: the processing device 10 loads the reception setting from the storage device 11, and controls the audio input device 13 to sense the played output calibration audio signal via the input control module 33 according to the reception setting to generate an input calibration audio signal.
Step S32: the processing device 10 compares the difference between the output calibration audio and the input calibration audio via the calibration module 36, and adjusts the playback setting and/or the reception setting according to the difference.
In one embodiment, the processing device 10 compares the volume of the output calibration audio signal and the volume of the input calibration audio signal at each frequency, and adjusts the volume correction parameters of the play setting and/or the reception setting to make the volume of the output calibration audio signal and the volume of the input calibration audio signal at each frequency approximately the same.
Therefore, the simulation device 1 has smaller difference between the audio signals played according to the adjusted playing setting and the audio signals sensed according to the adjusted receiving setting.
Referring to fig. 4 and fig. 7, fig. 7 is a flowchart illustrating playing of compensation audio according to an embodiment of the present invention. The embodiment can receive feedback operation of the user when the compensation message is played, and provide related information to improve willingness of the user to receive hearing correction. Compared to the simulation method shown in fig. 4, the step S14 of the simulation method of the present embodiment includes the following steps for implementing user feedback.
Step S40: the processing device 10 controls the audio output device 12 to play the original audio through the output control module 32. The original audio signal may be stored in the storage device 11 in advance, or the environmental audio signal received by the audio input device 13 in real time through the input control module 33, which is not limited.
Step S41: the processing device 10 controls the audio output device 12 to play the compensation audio through the output control module 32.
It should be noted that there is no necessary sequence between step S40 and step S41, and the compensated audio signal may be played first, and then the original audio signal may be played, without limitation.
Step S42: after playing the original audio and the compensated audio, the processing device 10 can control the human-machine interface 14 to receive a feedback operation (a second feedback operation) from the user through the interface control module 34.
In one embodiment, the processing device 10 may first control the human-machine interface 14 to display questionnaire information (second questionnaire information, for example, inquiring whether two groups of audio heard by the user are significantly different and which one is clearer) through the interface control module 34, and then receive a second feedback operation from the user.
Step S43: the processing device 10 selects corresponding hearing correction information according to the second feedback operation, and controls the human-machine interface 14 to display the hearing correction information through the interface control module 34.
For example, if the second feedback operation of the user selects two audio signals with obvious difference, the processing device 10 may read the hearing correction information (e.g. related information of hearing aid or related information of hearing ability rehabilitation) corresponding to the operation from the storage device 11 and display the information on the human-computer interface 14.
In one embodiment, the processing device 10 can further reserve the next hearing test or hearing correction through the human-computer interface 14.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the claims, so that equivalent variations using the teachings of the present invention are all included in the scope of the present invention, and it is obvious that the invention is not limited thereto.
