Another advantage contemporary hearing aids offer concerns
type of microphone used to amplify sounds. Without getting too complex, microphones come in two main styles – unidirectional and omnidirectional.
A unidirectional microphone has a limited, focused range and its use in a hearing aid reduces amplification of surrounding sounds. This type of microphone is good for individual conversations or watching TV.
An omnidirectional microphone picks up a variety of sounds in a wide physical range. In a hearing aid application, this amplification would be good for attending a sporting event, a church service or a business meeting.
Contemporary hearing aids, especially those with digital technology, utilize both types of microphones and can automatically detect which type of sound to amplify in any given situation.

past felt disappointed in past performance. However, great strides have been made in hearing aid technology and hearing testing that make it worthwhile for those suffering hearing loss to get new tests performed, or upgrade their current hearing aids.
