How Hearing Aids Receive and Convert Signals?

There are three basic types of technology that receive and convert the signals in hearing aids these days. The least advanced is the analog adjustable hearing aid, and it costs less than the other two types. This Type of Hearing Aid is adjustable by your audiologist for volume and other specifications. The factory will then custom make it for you. You can control the volume, or it will be controlled automatically.

Another type of circuitry found in hearing aids is called analog programmable. These are somewhat better than the analog adjustable because they can be programmed by using a computer. The audiologist sets different programs of sound capture and transmission for different listening situations. The user can select which program to use at any given time by using a remote control.

Digital programmable hearing aids are the most advanced and, of course, the most expensive. For years they were impossible and then they were impractical because they couldn’t be made small enough. That is no longer the case.
