Our First device designed specifically for Cadence ™

ACT-400 is based on the same architecture as Acoem’s trusted Cube ™ 4G noise monitoring terminal and IEC 61672 Class 1 Fusion™ 4G sound level meter. By removing the instruments’ display screen and accessories, but retaining all the proven technology plus the robust, waterproof casing, Acoem has been able to keep cost to an absolute minimum.

Even More Ergonomic

The sensor acts as a push system monitoring point rather than a hand-held meter, without the need for an external microphone or cabinet. It is mains powered but also has a back-up battery powersource. No support is required, and it can be automatically and remotely configured. In case of loss of connection, you will be able to set up alarms warning you of this event, but data will continue to be logged with information and data stored on an internal SD card.

The importance of monitoring noise pollution

Noise affects the way we work, live and play. As a society, we are continuously evolving and facing environmental challenges, including growing noise pollution caused by leisure activities, transport, aviation, construction sites and industrial activity.

The ability to maintain an ambient soundscape by controlling noise pollution is crucial to our wellbeing and health.
