DireCtional miCrophones

Your hearing instruments have directional 
microphones to help improve understanding in 
noisy situations like restaurants, large crowd 
events, parties and other environments where 
high levels of distracting noise is all around you.

When the directional mics are activated by 
pushing the multimemory button, sounds that 
occur directly in front of you will be emphasized, 
while sounds coming from other directions  
are reduced.

It is especially important that you face directly at 
those you are listening to, and keep them in your 
direct line of sight.
