How to demonstrate Intercom Noise Cancellation

In this video Piet tells you how to demonstrate our Noise Cancelling functionality that comes free with any purchase of Vingtor-Stentofon Intercoms running in PULSE or Alphacom mode. Make sure to download Piet’s quick guide to configuring an exact replica of Piet’s Noise Cancellation Demonstration Setup as well.

Active Noise Reduction - ANR aka Active Noise Cancellation or Active Noise Control

Sound is a pressure wave, which consists of alternating periods of compression and rarefaction. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out - an effect, which is called destructive interference.

The CPU in our IP stations runs a powerful algorithm that listens to the background noise and filters it out. The more powerful the CPU is, the better it will perform this task.
