It is necessary to repeat the main characteristics of deafness in the elderly: hearing loss, fear of loud voice, and poor coordination of fingers in some people. Therefore, their requirements for hearing aids are: high definition, less distortion, strong anti noise ability and easy operation.

There are three types of hearing aids on the market: box type, ear back type, customized inner ear and ear canal type. These hearing aids have their own advantages and disadvantages.

The price of the box hearing aid is relatively low, and the use cost (battery) is low. Part of the boxed hearing aids are very powerful and suitable for the deaf with severe hearing loss. The big adjustment knob is suitable for the elderly deafness patients whose hand movement is not coordinated enough. The disadvantage of the box hearing aid is that it is inconvenient to wear and use. The length of the outer lead is not only not beautiful, but also hinders the normal physical activity. When the machine box is placed in the pocket, a little activity will produce friction noise and affect the use. These are the defects that can not be overcome by the box hearing aid.

The ear back hearing aid has the advantages of convenient wearing, large power design, complete function setting and low price. The obvious defect of the ear back hearing aid is that it is easy to be eroded by the sweat from the head when it is put behind the ear, and then damage the components. In addition, it is very difficult to adjust the knob when using the ear back hearing aid, which is not suitable for the elderly who have poor coordination of finger movement.

There are three types of custom hearing aids placed in the ear, namely, it, ITC and CIC. The deep ear canal type is the smallest in volume, the lightest in weight (can be less than 1G), and the most concealed when worn (hidden in the ear canal). But the most commonly used form of the elderly is the auditory canal. It is also popular when hearing loss is severe. The common characteristics of customized hearing aids are: ① they are customized and are very suitable for the actual situation of users; ② they are placed in the ear and give full play to the original acoustic characteristics of the auricle and ear canal, with small noise, less distortion and high clarity; ③ they are stable and comfortable to wear because of their small size; ④ their concealment is the most satisfactory advantage for many users who do not want others to know their deafness defects; ⑤ more importantly, it is easy for the elderly to adjust.

Small and customized hearing aids also have disadvantages. If they are not stored properly, they are easy to be lost, which should be paid attention to by the elderly. As for the price, generally speaking, customized hearing aids are the most expensive of the three categories.
