Noise Monitor

The noise warning sign and interface module can be mounted on a wall or other suitable surface. An optional adjustable VESA mount can be used for more secure or corner mounting if needed. It measures the sound levels in line with the noise measurement standards, stores the results, and makes them available to the LiveNoise Supervisor and Reporter software over your network. An HDMI output can display the live sound levels on a computer monitor or HDMI television.

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.

noise display with wifi network connect

A system can consist of one or more LNT enabled noise monitors. They connect to your local area network using either WiFi or a wired Ethernet connection.

The noise monitors can work alone, connected to a display, they can be connected to the Supervisor software for real-time display, or they can upload to the cloud server for online reporting.


The Noise Warning Sign can be mounted on a wall using a single screw. The LiveNoise Terminal is mounted close by using two screws or can just sit on a shelf or other suitable surface.

If a more secure mounting method is needed or you want to angle it away from the wall then an adjustable VESA mount is available. Please contact us for more information.


A standard USB cable (included) connects the LiveNoise Terminal to the Noise Warning Sign.


The system requires 5V DC, which is provided by the power adapter that is included. The LiveNoise Terminal will need to be within 3m of a power outlet.

Mounting Noise Sign and Interface

Network Connection - WiFi or Ethernet

The LiveNoise Terminal 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 LiveNoise Terminal 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 the network name and password to connect up. If you prefer a wired approach then connection can be made via an Ethernet connection (RJ45).
