Ordering Information

The LNT LiveNoise Interface is for customers who already have SoundEar 3 or SoundEar 3 Industrial noise warning signs, or the SoundEar 3-320 noise processor. The LNT module is added to your existing SoundEar 3 units to provide data logging, network connection and the ability to display the sound levels on a monitor or TV via its HDMI connection.

LiveNoise System

With the LNT module connected, the system 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.

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.


Your existing Noise Warning Sign may already be mounted on the wall or on a VESA mount. The LiveNoise Terminal should be mounted close by using two screws or can just sit on a shelf or other suitable surface.

An additional security bracket is also available. Please contact us for more information.


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


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.

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).
