Hearing Aids Features That You Need to Know Before Buying
The first feature is 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. Their autonomous nature makes it turn itself on when the sound level in the room goes 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.
You can also check the ones that reduce noise. It enables the hearing aid to reduce the amplification in the spectrum. 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. It has the ability to relay both the speech and noise at the same time. Some hearing aids are able to manage noise by breaking the frequencies up into smaller pieces. It does not reduce noise but balances between speech and noise.

Memory is also one of the features in hearing aids. These are just different settings for different situations such as quiet places, noisy places, and music or telephone. The two types of memory are a manual memory 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. Some hearing aids have combination of both manual and automatic memories.

Another feature is called feedback cancellation. The whistling sound that comes back to your ear when you put your hand over it is known as feedback. It is designed in such a way that it prevents that whistling sound from coming back to your ear.
Band is also one of the features found in the hearing aids. Bands are features found in the hearing aids that are used in adjusting the volume in the hearing aids. When we have more bands it will also mean more control when your hearing aids are programmed to your ear.
Another feature channels. These are features that are used to improve part of the hearing aid that keeps off the loud music. It is solely responsible for noise reduction. If you want to control more noise then you should think of having more channels.
