Description

Digital noise reduction technology embedded inside hearing aids is one approach to combating this problem. It allows the wearer to block unwanted noise and focus on specific sounds.

Directional Microphones are Available in Certain Digital Hearing Aids – Key Points to Know Hearing aids are marvels of advanced technology, and they keep getting better. As hearing aid technology develops, new features provide better hearing. The directional microphone is one of these new features. This device allows its users to have a more natural listening experience, making it a popular addition to many modern hearing aids. Older hearing aids relied on omnidirectional microphones to amplify sound. This type of microphone picks up on sounds from all directions equally. When used in a quiet setting (such as in the home), an omnidirectional microphone works quite well, but it is not as effective in noisy environments. Directional microphones make up for this by focusing on sounds that come from in front of the wearer. Users can focus more clearly on what the people in front of them are saying, rather than being distracted by background noise. Because both types of microphones have their own advantages, many hearing aid designers will incorporate both into their devices. Directional microphone usage varies from hearing aid to hearing aid. Some devices utilize a small switch that allows the user to manually flip between microphones. Other hearing aids can automatically determine which method is most effective and switch itself to the optimum microphone. A third type of hearing aid microphone is the adaptive directional microphone. Instead of focusing in the front or all around, this type of microphone can pick up on the direction that speech signals are coming from and focus its amplification accordingly.

where many people are speaking, adaptive microphones can be troublesome, but they are usually accompanied by a switch that allows the user to access a “forward only” listening mode. Directional microphones are included in hearing aids for all ages, but caution must be applied when this feature is used by children. Because kids develop much of their language skills from listening to the people around them, a directional microphone may cause them to miss out on an important developmental experience. It may also reduce a child’s ability to hear traffic while playing. Parents should be sure that their child’s directional microphone is only turned on in appropriate situations. The advantages of the directional microphone outweigh its flaws, allowing it to dramatically increase its wearer’s ability to hear.
