Thanks to 5 divided microphones the U49 voice recorder can record audio from certain direction at a distance of 15 m and considerably reduce background noise of the microphone. 

What makes it possible? In case the recorded object is situated aside from the direction of the microphones operation the signal is “cancelled” due to phase difference of sound striking each microphone. In case the recorded object is situated straight in the direction of the microphones operation – sound waves are summarized and the signal is amplified.

Microphone noise is reduced according to the same principle: the noise sound waves do not coincide and the recorded sound waves summarize, that’s why the sound is “cancelled” while the target sound is amplified on the contrary. Noise reduction runs according to the formula:  Аn = А1 /sqr(N) with N being the number of microphones, А1 – the noise background of one microphone, Аn – the noise background of N microphones.

Microphone operation coverage area bears some resemblance to an oval. (see Fig.):


The readings for the diagram were taken with the voice recorder put into the sound-proof open drawer at the distance of 1.5 m from the sound source.

Looking at the diagram we can see that the sound is best of all recorded in the direction of the voice recorder, and much worse on each side and behind of it.

Judging by all the above we can conclude that EDIC-mini Tiny16 U49 will help you to record exactly what you need without anything irrelevant.
