How to choose hearing aids for people who sweat easily

We all know that electronic products, especially hearing aids, should pay special attention to moisture-proof and water-proof. In the face of hearing aids, people have a question: is it good for people who sweat a lot to wear ear back hearing aids? How to choose the right style?

There are several main types of hearing aids, including: traditional ear back machine, ric type, inner ear hearing aids (including ear cavity type, ear canal type, deep ear canal type). Among them, the main body of the traditional ear back and ric hearing aids is located behind the ears, while all parts of the inner ear hearing aids, including the main body, can be placed inside the auricles, without external parts behind the ears.

Hearing aids all have certain waterproof function, but the sweat component is complex, and the threat to hearing aids is obvious, which needs to be taken seriously. Which of these styles is more suitable for people with a lot of sweat? To know the answer, we should first understand the auricle and ear canal.

Understanding auricle

Auricle is what we call “ears” everyday. They are located on the left and right sides of the head and form an angle of about 30 degrees with the head. The auricle is mainly composed of semicircular elastic cartilage plate, which forms several ridges and grooves on the cartilage surface, among which the main ridges are auricle, contra auricle, tragus and contra tragus, which are surrounded by concha. The whole auricle is covered with thin, smooth and hairy skin; these skin are thin and lack of subcutaneous tissue; they generally do not sweat autonomously.

Understanding the external auditory canal

The external auditory canal starts from the bottom of the concha cavity and ends inwards at the tympanic membrane; the total length is about 2.5-3.5cm; the external 1 / 3 is composed of cartilage, which is the cartilaginous external auditory canal; the internal 2 / 3 is composed of bone, which is the bone of the external auditory canal.

The skin of cartilage is about 1-1.5 mm thick, which contains hair follicles, sebaceous glands and cerclavicular glands. It lacks sweat glands, so it will not sweat autonomously;

The thickness of bone skin is only about 0.1mm, there is no hair follicle, no gland structure, including no sweat glands, no spontaneous sweating.

When people with more sweat use ear back hearing aids, the auricle itself generally does not sweat autonomously, but the head close to the auricle is one of the main sweating parts; when people with more sweat wear ear back hearing aids, the host hanging on the back of the ear is close to the head, near the hair root, the machine can be easily surrounded by sweat. In the long run, the hearing aid will be affected by sweat, which will affect the service life of the hearing aid.

When people with more perspiration use the inner ear hearing aid, the cavity of the concha and the outer ear canal will not sweat autonomously, and they are also far away from the perspirable parts; when people with more perspiration wear the inner ear hearing aid, the perspiration can not easily contact with the hearing aid, and to a certain extent, keep the hearing aid dry; only the maintenance of the regular frequency is enough, and the life will not be affected by more perspiration. This is the reason why the daily match maker often mentions that “the inner ear machine is not afraid of sweat”.

People with more sweat can choose hearing aids like this:

1. If the hearing loss is not too serious and the ear condition allows, people with a lot of perspiration can preferentially choose the “inner ear hearing aid”;

2. When the hearing loss is serious and the power of the inner ear machine is not enough, it is suggested to select the “ear back hearing aid”.
