Hearing Aids Features That You Need to Know Before Buying

Directional microphones. 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. 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 fitted with a unique feature that allows them to follow moving sounds or reduce several different sounds at the same time.

Another feature they possess in noise reduction ability.  This function reduces amplification at the frequencies where there is no noise and speech.  In case you take a fan running in the background it will speech it as much as it will amplify it  You will be able to hear the fan moving. It is also designed to transmit both speech and noise at the same time. Theere are different types as some can handle 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. We have two ways of memory thus manual and electronic memory. We use the push button to activate memories since it 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. Not all of them, but some hearing aids have mix of both manual and automatic memories.

We also have feedback cancellation.  Feedback is the whistling sound that comes back to your ear when you put your hand over it. The whistling sound will be avoided from coming back to your ear by the use of a unique feature known as feedback cancellation.

Another a feature found on the hearing aid Ada Ok is known as a band. The a feature that is responsible for adjusting volume in the hearing aids is known as bands. 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.
