Compact, in-the-ear, rechargeable hearing aid/ hearing amplifier.Compact, in-the-ear, rechargeable hearing aid/ hearing amplifier. Notes: Does your father need you to shout in order to hear you? Does your mother keep the TV volume so high that it disturbs the rest of the family? Then maybe you can get them to check out a hearing aid. A new range of hearing aids are now available in the market. These are off-the-shelf, over-the-counter products that are inexpensive and easy to select and purchase. Unlike the traditional hearing aids which require you to go to an audiologist and get the hearing aid programmed specifically for you, these are more general purpose in nature and provide simple amplification. Think of them as the equivalent of off-the-shelf reading glasses compared to prescription lenses. Ideally suited for elders who require simple amplification in order to hear.
