Embodiment Construction
[0038] The following is further described in detail through specific implementation methods:
[0039] The invention provides a hearing loss early warning method, system, storage medium and audio equipment. Firstly, the concept of hearing loss index is introduced, and first, according to the theory of hearing loss formation, the concept of hearing loss index is explained:
[0040] A large number of scientific studies and experiments have shown that human hearing impairment can be described by volume intensity and duration, such as figure 1 As shown, expressed as S=H(T), this function represents the relationship between the volume intensity S and the duration T of the hearing loss, that is to say, the volume intensity S lasts for T minutes and hearing loss will occur. figure 1 S in e It is called the critical volume level of hearing damage. When the volume is lower than this threshold, hearing damage will not be caused, otherwise it may cause hearing damage. T e is the volum...

The invention belongs to the technical field of hearing protection, and relates to a hearing impairment early warning method and a system, a storage medium and audio equipment, and the hearing impairment early warning method comprises the following steps: S1, carrying out the statistics of the continuous playing time of an earphone and the volume intensity of the earphone, and obtaining the critical volume intensity of impairment; wherein the critical intensity of the impairment is a default storage parameter when the earphone leaves a factory; S2, judging whether the volume intensity of the earphone is smaller than the critical volume intensity of the impairment or not, if so, returning to the step S1, and otherwise, executing the step S3; S3, calculating the critical time of the impairment according to the volume intensity of the earphone; S4, judging whether the continuous playing time of the earphone is greater than the critical time of the impairment, if so, executing the step S5, and if not, returning to the step S1; and S5, lowering the volume intensity of the earphone to the critical volume intensity of the impairment, and sending out an alarm prompt. The problem of hearing impairment caused by long unconscious earphone use time and large earphone volume of a user in the prior art is solved.
Description
technical field [0001] The invention belongs to the technical field of hearing protection, and in particular relates to a hearing loss early warning method, system, storage medium and audio equipment. Background technique [0002] With the rapid promotion of true wireless TWS earphones, more and more consumers choose to wear Bluetooth earphones for voice calls and music playback, etc. Many users wear earphones for a long time and have a strong dependence on earphones. Medical research shows that wearing headphones for a long time will cause irreversible damage to human hearing when the playback volume is not well controlled. The current solution for volume control and protection of human hearing is mainly to detect the volume intensity of earphone playback: when the intensity exceeds the threshold, an alarm message is generated or the volume is lowered. Although the above scheme can play a certain protective role, there are still deficiencies. [0003] First of all, the du...
