Low Cost Noise Monitor

This LiveNoise monitor is fitted with a low cost microphone. While it gives an accurate measurement of the relative sound level, it is not intended for applications that need a monitor meeting standards such as IEC 61672 and ANSI S1.4. Please see our other noise monitors for these applications.

Typical Applications

The LNT-M is ideal for monitoring long term relative noise levels and warning when levels go unexpectedly high. A typical application would be monitoring for high pressure steam leaks in an industrial environment.

It is also ideal for monitoring the noise levels in open plan offices. A mixed system including this low cost version along with the LNT-320 or LNT-EAR noise monitors can be used to monitor larger areas with additional accuracy at key locations.

networked noise monitors

The noise monitor can communicate 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 long term reports. Or you can use the Web Reporter for online noise reports. An HDMI monitor can be connected to provide a large display of sound levels.


The LiveNoise Terminal is mounted using two screws or can just sit on a shelf or other suitable surface.

If a more secure mounting method is needed then an additional security bracket is available. Please contact us for more information.


The system requires 5V DC, which is provided by the power adapter that is included.


mounting the noise monitor
Mounting Plate - Two Screws

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).
