Audio Demonstrations

Please get an impression of the efficiency of LINGUA. Each recording presents the audio signal received with LINGUA ON and OFF. You will instantly notice the difference.
You hear audio-recordings with activated (for some seconds) and then deactivated (for some seconds) LINGUA.

1. Recording from 40 meters with noise-level at S7
   
2. Recording from 20 meters with crackling noise at S8
   
3. Recording from 40 m before formation of a thunderstorm
   

From time to time we will replace or supplement these audio files with new recordings in order to give you an impression of other noise situations.
Please contact us! We like to support you, even with very individual noise-problems.
