Exactly What Are They?
Sufficiently small to suit inside or behind the ear, these electronic devices develop sounds louder, allowing users to learn better in many environments. Aids usually do not actually improve auditory performance, but merely amplify sound. Most contain a microphone, an amplifier, along with a receiver which provides augmented sounds into the ear. Batteries are usually needed to power the device’s electronics.
Who Uses Them?

Much more versatile compared to the analog version, a digital device converts sounds waves in numerical codes, amplifies, and delivers them to the ear. Since the numerical codes contain details about loudness, direction, and pitch, it is much easier to alter them based needs in the user. As you may expect, these sophisticated aids are typically more expensive than basic analog models. But like anything else, you get whatever you pay for.
