Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a remote hearing device calibration method, which is applied to a server, and as shown in fig. 1, the method of the invention comprises the following steps:
step 101: acquiring a test signal; the test signal is an electric signal remotely transmitted from the client to the server, the electric signal is a signal transmitted to the client by the acoustic coupler, the acoustic coupler is used for converting an acoustic signal sent by the hearing device according to a test instruction into the electric signal, and the test instruction carries the calibration value; the calibration values are used to cause the hearing device to emit an acoustic signal having acoustic signal parameters of a target value, the target value corresponding to the calibration values, the acoustic signal parameters comprising a frequency and/or an intensity.
The client machine body provided with the client can be a mobile phone, a tablet computer, a notebook computer, a desktop computer and the like. The client and the server are connected through a wireless network. The hearing device can be a medical grade pure-tone audiometer or a hearing test software, and pure tones are played through electronic equipment such as a mobile phone or a tablet for a patient to carry out hearing tests.
Calibration of a hearing instrument refers to calibrating the condition in which the hearing instrument emits different frequency and intensity values. When the hearing device receives a test instruction carrying the calibration value, an acoustic signal is sent out, and whether the hearing device needs to be calibrated is judged by detecting whether the acoustic signal parameter value (frequency value and intensity value) of the acoustic signal is a target value.
The sound coupler has a sound insulation function and can convert sound signals into electric signals, the electric signals are transmitted to the client after analog-to-digital conversion, and then the client remotely transmits the digital electric signals to the server through a network. The server is able to derive the frequency value and the intensity value of the acoustic signal emitted by the hearing instrument by measuring the digital electrical signal. According to the invention, after the collected sound signals are converted into the electric signals by using the sound insulation and sound coupler, the electric signals are directly and remotely transmitted to the server for testing and calibrating the frequency and the intensity of the pure sound signals without using precision instruments such as a sound level meter, so that the calibration cost of the hearing equipment can be reduced, the hearing equipment does not need to be checked, the time is saved, and the user can quickly and conveniently complete the calibration of the hearing equipment.
As an embodiment, the calibration value generation method includes:
firstly, acquiring a parameter range of an acoustic signal; the target value is within the acoustic signal parameter range.
Then, distributing a plurality of basic points at equal intervals in the range of the acoustic signal parameters, wherein each basic point corresponds to one acoustic signal parameter basic value in the range of the acoustic signal parameters; the base value of the acoustic signal parameter comprises a target value, the base point having a sequence number, the sequence number increasing as the base value of the acoustic signal parameter increases.
And finally, determining a base point corresponding to the target value to obtain a target point, and taking the serial number of the target point as a calibration value.
Alternatively, when the acoustic signal parameter is intensity, the intensity range is 0-100dB, and a plurality of intensity values may be selected as the target values within the intensity range. 10000 basic points are distributed at equal intervals within the intensity range of 0-100dB, each basic point corresponds to an intensity value, 0dB corresponds to the 1 st basic point, the serial number of the 1 st basic point is 0, 80dB corresponds to the 1001 st basic point, the serial number of the 1001 st basic point is 1000, 86dB corresponds to the 2001 th basic point, the serial number of the 2001 th basic point is 2000, 100dB corresponds to the 10000 th basic point, and the serial number of the 10000 th basic point is 9999. If the target value is 80dB, the calibration value corresponding to 80dB should be 1000; if the target value is 86dB, the calibration value corresponding to 86dB should be 2000.
When the acoustic signal parameter is frequency, the frequency range is 63Hz-10000Hz, and the target value can be selected from 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz and 8000 Hz; 10000 basic points are distributed at equal intervals in the frequency range of 63Hz-10000Hz, each basic point corresponds to a frequency value, and the calibration value corresponding to each target value can be obtained by adopting a calibration value generation method with the same intensity.
Step 102: and measuring the acoustic signal parameters of the test signal to obtain the actual values of the acoustic signal parameters of the hearing device.
The frequency or intensity measurement is performed on the test signal to obtain an actual value of the frequency or the actual value of the intensity of the acoustic signal emitted by the hearing device. In case the hearing instrument is normal, the measured actual value should be the target value, or the actual value should differ from the target value by an amount within an allowed error range.
Optionally, the hearing device tests the condition that the intensity value is 80dB, the test instruction carries a calibration value 1000 corresponding to the target value of 80dB, an acoustic signal sent by the hearing device is converted into an electrical signal by the acoustic coupler to obtain a test signal, and the test signal is subjected to sound intensity measurement to obtain an actual intensity value of the hearing device, where the actual intensity value corresponds to the target value of 80 dB.
Step 103: an output error of the hearing instrument is determined from the actual value and the target value.
The present invention takes the absolute value of the difference between the actual value and the target value as the output error of the hearing device, e.g. if the hearing device is tested for a strength value of 80dB, the target value is 80dB, and if the actual value is 83dB, the output error of the hearing device is 3 dB.
Step 104: and judging whether the output error is within an allowable error range.
Step 105: if the output error is not within the allowable error range, the actual value is calibrated by adjusting the size of the calibration value corresponding to the target value, so as to compensate the output error of the hearing device.
comparing the actual value with the target value to obtain a comparison result;
if the comparison result is that the actual value is larger than the target value, reducing the calibration value corresponding to the target value;
and if the actual value is smaller than the target value as a comparison result, increasing the calibration value corresponding to the target value.
As an optional implementation, decreasing the calibration value corresponding to the target value includes: searching a calibration value adjustment amount corresponding to the phase difference in the adjustment amount corresponding relation table, and subtracting the calibration value corresponding to the target value from the calibration value adjustment amount to obtain an adjusted calibration value; the adjustment quantity correspondence table reflects a correspondence between a phase difference quantity, which is an absolute value of a difference between an actual value and a target value, and a calibration value adjustment quantity. Increasing the calibration value corresponding to the target value comprises: and searching a calibration value adjustment amount corresponding to the phase difference in the adjustment amount corresponding relation table, and summing the calibration value corresponding to the target value and the calibration value adjustment amount to obtain the adjusted calibration value.

Increasing the calibration value corresponding to the target value comprises: determining a calibration value difference value according to the output error of the hearing device, obtaining a proportionality coefficient according to the ratio of the calibration value difference value to the total number of the basic points, taking the product of the calibration value and the proportionality coefficient as a calibration value adjustment amount, and summing the calibration value corresponding to the target value and the calibration value adjustment amount to obtain an adjusted calibration value.
In an optional embodiment, after obtaining the adjusted calibration values, the remote hearing device calibration method further comprises: and saving the adjusted calibration value, and remotely transmitting the adjusted calibration value to the client so that the client sends the adjusted calibration value to the hearing device.
During the execution of the hearing device calibration, the calibration value meeting the error tolerance range is not modified, and the adjusted calibration value can be stored in the server, or can be stored in the client or the hearing device, so that the hearing device can output an acoustic signal according to the adjusted calibration value.
In an optional embodiment, if the output error is within the allowable error range, the target value is switched, and the calibration value corresponding to the switched target value is remotely transmitted to the client, so that the client notifies the hearing device to emit an acoustic signal having the acoustic signal parameter of the switched target value according to the calibration value corresponding to the switched target value.
After the test calibration operation has been performed for all target values, the calibration of the hearing instrument is ended. Optionally, the order of calibrating the hearing device is to perform a test calibration operation on the respective frequency target values and then perform a test calibration operation on all the sound intensity target values at each frequency target value.

And if the slope of the fitted straight line is not in the preset slope range, determining the sound intensity linear distortion.
The user can judge whether the hearing device is continuously available or not by detecting the linear distortion of the acoustic signal parameters and combining the hearing calibration result. If the adjusted calibration value still enables the actual value of the acoustic signal parameter output by the hearing device not to meet the error requirement and the sound intensity is linearly distorted, the problem of aging or damage of the hearing device is indicated, the hearing test result can be seriously influenced by using the hearing device, and the hearing device is required to be replaced in time.
