It is necessary to repeat the main features of the elderly deafness: inaudible, afraid of loud, and poor coordination of the movement of some fingers. Therefore, their requirements for hearing aids are: high definition, low distortion, strong noise immunity and easy operation.

There are mainly 3 types of hearing aids on the market: box type, ear type, custom ear and ear canal type. These hearing aids have their own advantages and disadvantages.

The box hearing aid is relatively inexpensive and the cost of use (battery) is low. Some box-type hearing aids are powerful and suitable for use by deaf people with extremely high hearing loss. The use of large-sized adjustment knobs for elderly deaf patients with insufficient hand movements is also a major advantage of box-type hearing aids. The disadvantage of the box type hearing aid is that it is extremely inconvenient to wear, and the length of the outer wire is not only unsightly, but also hinders normal limb movement. The case is placed in the pocket, and a slight activity can cause frictional noise and affect the use. These are the defects that the box hearing aid cannot overcome.

The ear-back hearing aid has the advantage of being convenient to wear, and the power design can be large, the function setting can be comprehensive, and the price is not too expensive. The obvious drawback of the behind-the-ear hearing aid is that it is easily eroded by the sweat flowing down the head when it is placed behind the ear, which in turn damages the components. In addition, when the behind-the-ear hearing aid is used, the adjustment of the knob is difficult, and it is very unsuitable for the elderly who have uncoordinated finger activity.

Customized hearing aids placed in the ear are classified into 3, In-Ear (ITE), Ear Canal (ITC) and Deep-Earth (CIC). It is the smallest in the deep ear canal, the lightest in weight (can be less than 1 grams), and the most concealed when worn (deep in the ear canal). But the most used by the elderly is the ear canal. Intra-ear style is also popular when hearing impairment is severe. The common features of the customized hearing aids are: 1Because it is customized, it is very suitable for the user’s actual situation; 2Because it is placed in the ear, the original acoustic characteristics of the auricle and ear canal are fully utilized, the noise is small, the distortion is less, and the degree of clarity is High; 3 due to its small size, wear is stable and comfortable; 4 its concealment is the most satisfactory advantage for many users who do not want others to know their own deafness defects; 5 more importantly, it is easy for the elderly to adjust.

Small custom-made hearing aids also have shortcomings that are easily lost if stored improperly. This is a problem that older people should pay attention to. As for the price, in general, the custom type is the most expensive among the three major types of hearing aids.
