Digital aids vary from conventional aids in their ability to duplicate different levels of sounds. The result is amplification that is fitted to each individual's hearing loss and assures balance and harmony in the replication of sound. However, not everyone is a candidate for a digital hearing aid. The selection of an appropriate hearing aid is dependent on the type of hearing loss present and the individual's personal needs. The earmold then carries the amplified sound to the eardrum.
Most hearing aids have an adjustable volume control and are powered by small, replaceable batteries.
Although designed for durability, hearing aids require regular maintenance. A general checkup, cleaning, and adjustment should be scheduled as recommended by your audiologist. Hearing aids and hearing loss have been getting a lot of media attention over the past several years, however not all of the attention has been positive. That's why we have always talked about controlling background noise and loud sounds not eliminating them. There have been very important advances in hearing aids in the past several years.
