At the most basic level, hearing aids are amplifiers. An amplifier cannot restore normal hearing or inner ear function. Hearing aid wearer’s must set their expectations realistically. In other words, the bionic ear does not exist. That said, there is available today an amazing array of hearing aid technology, which can immeasurably improve the quality of life for those with hearing loss.

Hearing aids that fit into the ear are custom built products, and are available in several sizes. An impression of your ear must be taken to order an in-the-ear device. One is also made when ordering an ear mold, which secures a behind-the-ear hearing aid in the ear.

Hearing aids are separated into two basic types, conventional and programmable. Conventional hearing aids have been used in various forms for decades. These analog devices reproduce sound from a microphone at an increased volume, which the user can adjust manually. Tone, pitch, output, and various other parameters can be adjusted on these devices with the use of screw-set potentiometers.

Programmable hearing aids are further divided into two classes, often referred to as digitally programmable, and fully digital. Those devices that are digitally programmable are a hybrid of the analog and digital aids. This analog hearing aid contains a digital component or components which can be used to program the parameters of the hearing aid or to supply memory for certain settings. Fully or true digital hearing aids process sound by converting it into numerical representation (binary code) within a sound processor.

The main advantage of true digital hearing aid technology is the ability to perform complex signal processing, allowing the hearing aid to make decisions based on the user’s changing environment. Volume change and frequency response as well as noise suppression is accomplished simultaneously.

Do some research first, but trust your audiologist to guide you through the selection process. It would be helpful if you can prioritize your needs with regard to the hearing aid. What is most important to you – size, programmability, cost, having a remote control?
