Intelligent Volume Control – IVC

A special audio processing method developed by Commend, IVC enables Intercom stations to ‘listen’ for background noise and adjust the station’s sound level accordingly. As a result, the volume level automatically matches the ambient noise level by going up or down, thus maintaining precisely the level that is most comfortable for the human ear. This way, the helpful voice of the operator is easy to understand at the tunnel emergency station despite the deafening traffic noise in the background. The same applies to the Intercom station in the production hall, where Intelligent Volume Control ensures that critical announcements and instructions cannot get lost in the background noise

The clarity and intelligibility of Intercom communication does not only depend on the quality of the speech signal being transmitted. The other essential criterion is how well the Intercom station is able to adjust to its surrounding conditions.  Commend Intercom stations stand the test of everyday use in a variety of different environments. The acoustic spectrum ranges from absolute silence to extreme noise. Ensuring optimum intelligibility even under extremely noisy conditions is a very special challenge. With Intelligent Volume Control (IVC), our audio engineers have come up with a unique solution. IVC delivers voice messages in superior quality and clarity, even through the thickest veil of background noise. At the same time, it ensures that the voice signal always arrives at a comfortable volume level, even if there is low background noise. IVC is a critical function for many devices and applications – from the emergency call station in a road tunnel to the industrial Intercom station in a production hall.
