Several Different Hearing Aids

The working principle of all-digital hearing aids can be summarized as collecting sound first and converting it into relatively simple analog signals. Then these analog sound signals are digitized, and the noise signals in the sound are filtered through spectrum analysis through digital processing to achieve the function of noise reduction. At the same time, it can also deal with the sound from different directions of sound sources, which is a very potential type of hearing aids.

Bone conduction hearing aid

Bone conduction hearing aids use the principle that sound can be transmitted through solid state to transmit sound signals directly to the inner ear by shaking the skull, not through the outer and middle ears. Bone-conducting hearing aids do not have so-called earphones or earplugs, but instead a vibrator that generates vibration signals. The oscillator is compressed on the mastoid protrusion behind the ear. The oscillation of the oscillator causes the skull to oscillate and transmits the signal directly to the inner ear.

Air Conduction Hearing Aid

Air conduction hearing aids are the most common and widely used type of hearing aids in the market, which make use of the principle that sound can be transmitted through the air to the outer ear and then through the tympanic membrane vibration to the inner ear. Air conduction hearing aids can be divided into three categories according to their shape, namely, box type (pocket size hearing aid), ear back type and inner ear type. Among them, the ear-back type can be divided into the conventional ear-back type (BTE) and the built-in receiver type (RIC) hearing aids. From large to small, the inner ear type can be divided into three types: the whole ear concha cavity type (ITE), the ear canal type (ITC), the miniature version of the ear canal type (CIC), and the miniature version of the deep ear canal type (IIC).
