The Microphone Active Noise Reduction (MANR)
is an innovative technique which is based on an application of digital circuitry to filter background noise from voice signals. This is especially important in the area of communication on the bike, where understanding can be very affected through the wind noise.

MANR functions like this: a mixture of voice signal and wind noise is first amplified and filtered, then digitalized. A modern signal processor functions as Adaptive Noise Filter Module programmed to recognize voice from noise through fast constant calculations and to reduce the noise part as much as possible.

The result of the test drives showing the reducing of background noise between 20 to 30 Db. After filtering is wind noise noticable lower and also not depending on speed. That means, no matter which speed you drive your communication stays in a very good quality.

MANR is delivered integrated in following Magic Talk intercoms:

Speed: 230 Km/h

 
Result of the test drive

Reducing of the wind noise is between 20 to 30 dB. After filtering is wind noise noticable lower and also not depending on speed. That means, no matter which speed you drive your communication stays in a very good quality and relation between a voice and noise.
