At present, the output of high performance music headphones on the market uses frequency response characteristics as indicators, such as flat frequency response curve, wide enough bandwidth, and some stereo and spatial auditory control methods. For those with mild and moderate hearing loss, their hearing status has changed, and the above mentioned indicators are not sufficient. However, if they consider selecting hearing aid products, and the existing hearing aid products are designed to improve speech recognition rate by compensating for multi-channel output gain for people with hearing impairment of more than moderate degree, and reduce communication impairment, the output of sound is easily excessive for them. In summary, the listening devices (music headphones or hearing aid products) currently used by human beings only provide volume control, so that the pursuit of sound quality and loudness is excessive, and the reality that the pursuit of sound quality and shocking sound can further cause hearing loss is neglected. It is all the more likely that most music fevers have different degrees of hearing loss, and with age, hearing loss manifests itself primarily in an increase in the high frequency threshold (high frequency hearing loss). On the other hand, the triggered neurons usually in the positions where the low-frequency sound is perceived, because the energy consumption of the neurons in the parts for responding to the sound with different frequencies is different, the output of the flat frequency response curve of the earphone or the loudspeaker can cause over stimulation of a local or single frequency band, and the auditory neurons which are not damaged can start to generate hearing sensitivity decline due to the over stimulation along with the increase of the stimulation duration, so that hearing loss occurs.
In addition, the sound volume of the left and right ears of these music earphone products is uniformly controlled, and it is not considered that the hearing thresholds of the left and right ears of even a normal hearing person are different.
