Audio Demonstration

Click on the buttons below to hear how conventional AVC and SmartAVC™ respond to a high-frequency tone, to loud claps, and to white noise.

Start Here

Reduce speaker volume to the level at which you can still hear the voice clip comfortably with 100% intelligibility.

High-Frequency Tone

The frequency of the noise is too high to affect intelligibility. Conventional AVC overreacts. SmartAVC™ ignores it.

Loud Claps

The duration of the noise is too short to affect intelligibility. Conventional AVC produces static-like bursts. SmartAVC™ has appropriate slight response.

White Noise

Most white-noise power does not affect intelligibility. Conventional AVC raises volume 4 times (6 dB) louder than it needs to. SmartAVC™ raises volume only enough to maintain 100% intelligibility.
