Hearing Aids

Hearing aids use the same basic parts to carry sounds from the environment into your ear and make them louder. Most hearing aids are digital, and all are powered with a hearing aid battery.

Small microphones collect sounds from the environment. A computer chip with an amplifier converts the incoming sound into digital code. It analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. The amplified signals are then converted back into sound waves and delivered to your ears through speakers.                        

The SLN Surgicals Hearing aids vary a great deal in price, size, special features and the way they're placed in your ear. The following are common hearing aid styles, beginning with the smallest, least visible in the ear. Hearing aid designers keep making smaller hearing aids to meet the demand for a hearing aid that is not very noticeable. But the smaller aids may not have the power to give you the improved hearing you may expect.

Digital hearing aids take into account the sound around you. The device samples the sound in your environment at 1 million times per second. Then it compares the environment to your level of hearing loss, which is programmed into the hearing aid. After 40 million calculations, it adjusts accordingly. This all happens instantaneously and is completely automatic; the user does not have to control the volume or make any other adjustments. In this day and age, there is no reason anyone should be selling you a non-digital hearing aid.
