Description

Multi-mode volume-adjustable hearing aid

Technical Field

The utility model relates to a audiphone technical field especially relates to a audiphone of adjustable volume of multimode.

Background

The human ear is extremely vulnerable, and factors causing human ear damage comprise viruses, environmental noise, ototoxic drugs, heredity and the like, which can cause hearing damage of different degrees and states of the human ear, and can seriously cause hearing disability. The sound output by various earphones and loudspeakers is linear output, the received sound is subjected to nonlinear regulation by the auditory function of human ears, and the sound output by the earphones and the loudspeakers is not matched with the auditory function to cause auditory "sound damage", so that serious people cause hearing disorder or hearing disability. In real life, hearing impairment is not perceptible, and the problem may have become serious or irreversible when perceived, requiring assistance from hearing aids or cochlear implants, which increases the burden on the home and society.

The world health organization publishes a message: currently, 11 billion teenagers worldwide may have hearing loss due to the use of earphones. The strong sound can cause deafness and tinnitus, but studies show that: prolonged stimulation of low intensity sounds and prolonged cumulative stimulation can also lead to deafness, tinnitus. In real life, noise is ubiquitous. The data show that the incidence rate of hearing impairment of the newborn is 0.1-0.3%, the newborn develops to about 10% in the acquired period, 50% of 60-year-old people have hearing impairment of different degrees, and the contribution rate of various environmental sounds to the hearing impairment reaches 25% in the occurrence and development process of the hearing impairment, namely the hearing impairment is directly related to unscientific sound stimulation or unscientific auditory use.

Sounds are dynamically changing, especially music and natural sounds, with a large dynamic range of sound pressure, the minimum and maximum sound pressure levels of which may differ by more than 30dBsp l. At present, earphones are generally used for listening to external sound sources such as music or receiving calls, the earphones receive audio signals input by a playing device and input sound to human ears after volume control, and the sound output by the earphones is consistent in volume adjustment of sound with each frequency in a human ear hearing threshold range (the sound with each frequency is amplified or reduced simultaneously, the volume is changed linearly), and the sound is not adjusted and output according to the actual hearing state of a user. For some otological patients, the response thresholds of the inner ear neurons that sense sound to externally transmitted sounds of various frequencies are different. For example, people with high frequency hearing impairment who have a higher threshold for response to high frequency sounds may need a greater volume to hear. Therefore, when people with high-frequency hearing impairment listen to music through a common earphone, the whole volume of music input into human ears needs to be increased to listen to the sound of the high-frequency part of the music, and the increase of the whole volume also enhances the energy of the low-frequency sound. For people with high-frequency hearing impairment who do not have low-frequency hearing impairment, the low-frequency hearing impairment can cause damage to neurons of the inner ear which can sense low-frequency sound, and hearing impairment or tinnitus can be generated for a long time.

The appearance of hearing aid equipment solves the problems to a certain extent, however, practice shows that the existing hearing aid equipment has a single playing mode and cannot be adapted to users with different wearing requirements; and cannot be adjusted to the user's requirements for volume.
