A hearing aid is a device used to help hard-of-hearing people hear sounds better. In the past, a funnel-like amplification cone, called an "ear trumpet" or "ear horn", was used. Also sometimes used was a desk with a built-in amplifier into which a microphone and earphones could be plugged; these worked better than passive ear trumpets but were not portable.

Now, however, the most common style is a small electronic device that fits into the wearer's ear. The first variety of this device had a rectangular battery pack connected by a thin wire, intended to be held in a pocket. Such "body aids," though much more portable than the desk type, still suffered significant disadvantages due to sub-optimal microphone placement. Since the microphone was not near the user's head, it was susceptible to interfering sounds such as clothing-noise. Sound input was also distorted if the microphone was located below the mouth of a person with whom the user was conversing.

During the mid- to late 20th century, hearing aids that were carried in pockets were replaced by a more inconspicuous sort of model in which small zinc-air batteries were placed in the inserted unit itself.
