Directionality is
one of the determining components in a hearing aid that allows its wearer to distinguish speech from background noise
. Hearing aid directionality depends on directional microphone technologies, which vary from device to device.
What do directional microphones do?

to minimize unwanted background noise
and has the highest pickup sound from the front, unlike omnidirectional mics which capture audio in every direction.

What is the difference between omnidirectional and directional microphones?
An omnidirectional microphone
will in principle pick up sound equally from all directions
. The microphone will though become more and more directional the higher the frequency. … Directional microphones are seen in a number of variations, i.e. cardioid, hypercardioid and supercardioid.
How many directional mics are there?

An omnidirectional microphone is a microphone that picks ups sounds from all sides and directions, whether the sound is coming from the front, back or side of the wearer. This type of microphone is the technology traditionally used in hearing aids.
What is directional hearing?
