Analog hearing aids

Analog hearing aids

Analog hearing aids are the most basic type of hearing aid available. They have been around the longest and are the least expensive. Analog hearing aids amplify sound in a linear manner, meaning that the louder the sound, the more it is amplified. This can be beneficial for people who have mild to moderate hearing loss. However, people with severe hearing loss may find that analog hearing aids don’t provide enough amplification. In addition, analog hearing aids can be susceptible to feedback, meaning that they may produce a whistling sound.
