Noise Monitor

The LiveNoise LNT-SE Noise Monitor mounts on a wall using four screws. It just needs power (24VDC, adapter included) and access to a wired Ethernet or WiFi network.

LiveNoise System

The noise monitor communicates continuously with the LiveNoise Supervisor software to provide real-time noise levels, long-term stored noise measurements and high-noise alarms. The LiveNoise Reporter software can generate reports of the noise and alarms over daily, weekly, monthly or other custom periods.

Alternatively, the noise monitor can upload its measurements for you to view using our Web Reporter system.

wifi noise monitor connection


The LNT-SE monitor mounts with four screws that are accessible from the front of the case with the font panel removed.

The screws are not provided as the type depends on what the monitor is being mounted on - screws for wood, plugs and screws for brick. The noise monitor is lightweight and so does not need a strong structural mount.


The noise monitor comes with a 10m (32ft) power cable fitted through a weatherproof gland. This cable can be removed and shortened if necessary.

A 24VDC power adapter is included with each noise monitor. The 10m cable connects to the power adapter, which must be mounted indoors or in its own weatherproof enclosure.

installing the noise monitor

Network Connection - WiFi or Ethernet

The LNT-SE noise monitor can communicate with the LiveNoise Supervisor software to provide a real-time display of sound levels and for long-term noise measurement storage. With the Supervisor software running on a computer on your network, the LNT-SE noise monitor just needs access to the same network.

If you are only using the Web Reporter for you noise reporting then the LiveNoise monitor just uses the network connection to upload its measurements to the cloud server.

Wireless or Wired?

If a reliable WiFi signal is available then the noise monitor just needs to network name and password to connect up. If you prefer a wired approach then connection can be made via a weatherproof Ethernet connection (RJ45) on the bottom of the box.
