What is the microphone on the hearing aid?
The listener is a device that receives a sound that is amplified by the hearing aid and points to the ear canal of a person who has suffered a loss of hearing. Depending on the hearing aid style, the listener can be placed in the ear, around the ear or on the body. The listeners are either directional, omnidirectional or directional adaptive. The hearing aid could decide to use different types of listening microphones for different listening environments. Such devices have a microphone located inside or near the ear, allowing users of natural auditory skills to be perceived by sounds. These types of microphones also provide the user with the best ability to recognize where the sound comes from. However, feedback may be a problem because the microphone is located near the Speaker, which makes a reinforced sound to the user's ear.
Some users prefer to wear SL microphoneShe horn on his body. One common type of microphone in the body is designed to look like a necklace and receive sound on the user's chest. This type of microphone can be particularly useful for individuals who have suffered serious hearing loss and who want to avoid feedback. Older microphones on the body require a wire that leads from the microphone to the listening itself. Newer devices use wireless technology to transmit sound from the microphone to the hearing aid and no wires are required.
All microphones are designed as omnidirectional, directional or directional adaptive. Omnidicenic microphone gets sound from all directions. This can in some cases lead to interference with noise in the background. The directional microphonrophone receives sound from only one or more directions and is generally desirable, except when the user must be able to perceive background sounds. The adaptive microphone automatically switches between omnidirectional and directional depending on the listening environment.
Although technically is not a microphone for hearing aids, Telecoil is a similar device. It is a special circuit inside the hearing aid that picks up magnetic signals and converts them into a sound for users. Phones and some assistance listening devices produce electromagnetic signals. When the hearing aids are switched to Telecoil mode, the microphone on the hearing aid is switched off, allowing the user to hear only electromagnetic signals generated from the phone or auxiliary listening device without intervention from the background noise.
