Perfect Speech Intelligibility

Perfect Speech Intelligibility

Since its foundation over 50 years ago, Commend has been researching and perfecting the speech quality of its systems to provide customers and users with the highest possible speech intelligibility even under the harshest conditions.

In the multi-faceted world of Intercom acoustics, everything down to the smallest influencing factor is taken into consideration when it comes to perfecting acoustic qualities – from basic physical sound properties to signal processing and the selection of individual electronic components.

In doing so, Commend keeps extending the technical frontier.
