A hearing aid can be an effective way to compensate for hearing loss. Each technological innovation offers more features and functions in a more compact space. The directional microphone is one of these new functionalities. 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. 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. 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. How you use these microphones varies from device to device. 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. 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. 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. Children learn language by hearing the people around them speaking, but a directional microphone can limit a child’s exposure to this incidental speech. 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.

Despite its flaws, hearing aids equipped with a directional microphone can greatly increase a person’s ability to hear and interact with the world around him.
