What are the classifications of hearing aids?

Hearing aids are devices that help people with hearing loss amplify sound. They are divided into two categories: bone conduction hearing aids and air conduction hearing aids. Air conduction hearing aids transmit sound through air and are further divided into box hearing aids, in-ear hearing aids, neckband hearing aids, and behind-the-ear hearing aids.

A box hearing aid is a traditional type of air conduction hearing aid that usually consists of an external amplification unit and an earplug that is inserted into the ear. This kind of hearing aid is larger in size but relatively low in price, and is suitable for use in environments that require strong amplification volume.

In-ear hearing aids are smaller air conduction hearing aids that fit directly into the ear canal. This kind of hearing aid is smaller in size, more discreet to wear, and can be customized according to the user's hearing needs.

Neck-mounted hearing aids hang components such as amplification units and batteries around the neck, and connect earplugs through earphone cables. This kind of hearing aid is easy to carry and also convenient for users to make phone calls and other operations.

A behind-the-ear hearing aid is an air conduction hearing aid that fits behind the ear and delivers sound into the ear canal through a long, thin tube. This kind of hearing aid is relatively discreet and has a variety of listening programs and functions to meet different hearing needs.

In general, hearing aids come in a wide variety of categories, and users can choose suitable hearing aids based on their hearing conditions, lifestyle, and budget. Whether it is air conduction hearing aids or bone conduction hearing aids, they provide effective ways to improve hearing for people with hearing loss.
