Description
Technical Field
The invention belongs to the technical field of hearing protection, and particularly relates to a hearing impairment early warning method, a storage medium and audio equipment.
Background
Along with the rapid popularization of real wireless TWS earphone, more and more consumers choose to wear the Bluetooth earphone to carry out voice conversation, play music and the like, and many users wear the earphone for a long time, so that strong dependence is generated on the earphone. Medical research shows that when the earphone is worn for a long time, irreversible damage can be caused to the hearing of a person under the condition of poor volume control of playing. The prior solution for controlling the volume and protecting the hearing of the human ear is mainly to play the volume intensity by detecting the earphone: when the intensity is too high to exceed the threshold, an alarm message is generated or the volume is turned down. The scheme can play a certain role in protection, but still has the defects.
Firstly, the duration time needed for the different-intensity sound volumes to damage the hearing of the human ears is different, the sound volume of the earphone is not necessarily safe after being reduced, and if the duration time is long enough, the hearing is still damaged; secondly, the playing volume of the earphone is dynamically changed, and the hearing impairment of the earphone user is a superposition result of different volume intensities for a period of time, which is not considered in the prior art; in addition, the safety volume intensity of people at different ages is different, the hearing impairment parameters are different, and the time required for hearing recovery after broadcasting is paused is also different. Therefore, a comprehensive and strict hearing impairment pre-warning method is needed to protect and pre-warn the hearing of people with earphones.

s1: obtaining earphone use data and hearing impairment parameters, wherein the earphone use data comprises earphone volume intensity and continuous use time corresponding to the earphone volume intensity; the hearing impairment parameters comprise an impairment critical volume intensity, an impairment critical time and a hearing impairment power function index; the hearing impairment parameters are stored by default when the earphone leaves the factory;
s2: calculating a hearing impairment value for the time period according to the earphone usage data and the hearing impairment parameters;
s3: accumulating the hearing impairment values of each time period to obtain a hearing impairment index;
s4: acquiring an earphone warning threshold, wherein the warning threshold is stored by default when the earphone leaves a factory;
s5: judging whether the hearing impairment index is larger than the warning threshold, if so, reducing the earphone volume intensity to the impairment critical volume intensity and sending out an alarm prompt.
The principle and the advantages of the invention are that: when the earphone is worn, the hearing damage of the human ear can be judged by using a hearing damage index, the hearing damage index is integrated by a hearing damage value, and the hearing damage value is calculated according to the earphone volume intensity, the continuous use time of the earphone volume intensity and a hearing damage parameter; when the hearing impairment index is greater than the warning threshold, judging that the hearing of the user is impaired, prompting the user to stop using the earphone, and adjusting the volume intensity of the earphone to be below the critical volume intensity of the impairment.

S in FIG. 1 e Called the critical volume intensity of hearing impairment, when the volume is less than the threshold, hearing impairment will not occur, and conversely hearing impairment is likely to occur. T (T) e Is the volume intensity S e The length of time required to cause hearing impairment. (S) e ，T e ) The upper graph curve is divided into two segments. To the left a section of oblique line (i.e. T<T e ) Is that the volume is greater than S e Can be expressed by a negative power function, the more the volume intensity S isThe greater the length T required to produce a hearing impairment, the shorter. The curve expression is:

Intensity S 1 The time for causing hearing impairment is T 1 Minutes, S 2 The hearing impairment time is T 2 Minutes …, strength S m The hearing impairment time is T m The conditions that do not produce hearing impairment are defined as:

Assume that the rest and recovery time of the hearing of the human ear is T 0 If a certain S k ＜S e And duration t i ＞T 0 Indicating that hearing is restored { S } i I=0, 1, … …, k } discarded from S k+1 Starting to re-count, S set becomes { S ] i I=k, … …, m }. After the above processing, the hearing loss index Q corresponding to the volume intensity set S is expressed as:
equation 6:
wherein m is the length of the set S, S e To damage critical strength, T e For the critical time of hearing impairment, q is the exponent of the hearing impairment power function, and these three constants are uniquely determined by the hearing impairment curve. a, a i Obtained from the following relation: when S is i ＜S e ，a i =0, otherwise a i ＝S i 。
When Q is 1 or more, hearing impairment is generated. For safety, a number smaller than 1 is usually set as a warning threshold, and Q is used as the warning threshold th . At Q > Q th After that, the user is required to pause the earphone for a period of time, which is set as T 0 . The length exceeds T when the earphone is suspended 0 And (5) resetting Q and restarting the accumulated computation, otherwise, continuing to prompt an alarm.
