Acoustic Connected Terminal

The Acoustic Connected Terminal (ACT-400) is the newest addition to Acoem’s suite of noise monitoring terminals, sensors and meters. It combines the precision of a Class 1 sound level meter with the maximum protection of an outdoor kit and full connectivity via the Cadence™ noise management system as well as other open-source platforms.


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.
