A hearing aid can be an effective way to offset hearing loss. Every year hearing aids become more advanced and offer additional features and functions that were not previously available. The directional microphone is one of these new features. Many of today’s hearing aids incorporate this device, allowing the wearer to enjoy a more natural hearing experience.

The traditional standard for hearing aids was the omnidirectional microphone. When this style of microphone is in use, sound is amplified from all directions in equal measure. While this method works well in a quiet setting such as a living room, it is not conducive to noisier environments (such as a restaurant). In order to compensate for this, directional microphones focus closely on sounds emanating from the front. This allows you to hear what is being said in front of you while blocking out unimportant noise from the rest of the room.

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. In some cases users can manually switch back and forth between microphones, usually through a small switch. Other devices can pick up on which microphone is most useful in a given situation and will automatically switch back and forth.

A third type of hearing aid microphone is the adaptive directional microphone. This device offers variation in the direction of amplification, automatically picking up on speech signals and focusing in on the direction they are coming from. Adaptive microphones can be troublesome in crowded environments where many speakers are present, but the user can usually switch to a forward only mode in these situations.

Hearing aids designed for kids sometimes utilize directional microphones, but caution is needed when using these devices. 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. Children may also have difficulty hearing traffic with this type of microphone. Parents should make sure that their child’s hearing aid has an on/off switch for the directional microphone and make sure it is only turned on when appropriate.

The advantages of the directional microphone outweigh its flaws, allowing it to dramatically increase its wearer’s ability to hear.
