Rechargeable invisible hearing aids are small electronic devices that make louder sounds in quiet or loud environments to help people with hearing loss hear. If a patient’s hearing is caused by damage to the sensory cells of the inner ear, hearing aids can improve the patient’s hearing and speech comprehension. The more severe the hearing loss, the higher the magnification requirement for hearing aids.
Hearing aids are sound amplifiers. Because it is easy to use and has good effect, it is the main way to improve the hearing impairment and speech communication impairment of the hearing impaired. Proper use of hearing aids can help people with hearing loss improve their quality of life.
how do invisible hearing aids work to help us hear clearly
Seven basic structures of invisible hearing aids:
1.Microphones receive sound and convert it into radio waves, that is, convert sound energy into electrical energy.
2.The amplifier amplifies the electrical signal (transistor amplifying circuit).
3.Headphones (receivers) convert electrical signals into sound signals (ie, convert electrical energy into sound energy).
4.Put the ear mold (earplug) into the external ear canal.
5.Volume control switch. If the volume is increased, more current is required; turning the volume down reduces the current through the amplifier, making the sound lower.
6.Zinc-air battery or rechargeable lithium battery for power supply for amplifier.
7.Shell to protect the internal structural parts of the hearing aid.
The working principle of hearing aids is the process of sound and electricity conversion. According to different hearing loss conditions, the sound of different frequencies is amplified in a targeted manner to achieve the purpose of low sound amplification, loud sound and no noise. In the process of sound processing, hearing aids use new technologies such as intelligent noise reduction technology, binaural fusion, and dual microphones to improve hearing, especially speech intelligibility in noisy environments.
The structure of the rechargeable invisible hearing aid adopts a smaller and more sophisticated integrated circuit amplifier, which reduces the occupation of the limited space of the hearing aid. This will make the invisible hearing aid invisible recommend the popular invisible hearing aid GB2 (click to open). Its small size and clear sound make it a common choice for many people with hearing loss.
