5 Lessons Learned: Wellness

Special Features of Hearing Aids. We have directional microphones as a feature in hearing aids. Directional microphones are features find on hearing aids that are used mostly in noisy places like bar, restaurant or in a public gathering. Their operation is in such a way that they reduce sound from behind so that it does not interfere with noise in front. These directional microphones are available some of the styles of hearing aids i.e. BTE, OE, ITE, Half Shell, and ITC styles. These directional microphones are automatic meaning they automatically turn themselves on when the sound level in the room gets too high. They are also able to support moving sounds or reduce several different sounds at the same time. Noise the reduction is also another feature. This function reduces amplification at the frequencies where there is no noise and speech. Let us take for example a fan running in the background it will speak it as much as it will amplify it. As a result you hear the fan running. This feature is also possible to relay both speech and noise at the same time. some hearing aids can manage noise by breaking the frequencies up into smaller pieces. Noise reduction here does not mean the actual noise but just the balance between noise and speech.

Another important feature is known as memory. Memories are just different settings for different situations such as quiet places, noisy places, and music or phone. The memories come into forms thus automatic and manual. These memories are being activated by the use of a push button that allows you to have different settings. We can use the push button to activate the manual memory, and the electronic memory is turned on by the hearing aid itself.Push button turns on manual memory while hearing aid turns on the automatic memory. The hearing aids beeps when the memory is on to alert you on which memory you are using. It is also possible for some hearing aids to have combination of both manual and automatic memories.

Another feature is called feedback cancellation. This is the whistling sound that comes back to your ear when you put your hand over it is known as feedback . This feature can take down that whistling sound from coming back to your ear. Band is also one of the features found in the hearing aids. These are the elements that are used to adjust the volume in hearing aid. When your hearing aid is programmed to your ear it means more bands will have more volume control.The more the bands the more the volume control when the hearing aid is programmed to your ear. Hearing Aids has another feature known as channels. The loud sound is controlled by an element in the hearing aid known as the channel. Its primary function is to reduce noise. When you want to minimize the noise fully then you should use more channels.
