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.

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.
