  • Class 2 Noise Processor
  • Monitors and stores sound levels
  • Network connection (WiFi or wired Ethernet)
  • HDMI monitor output available


  • Open plan office and call centre noise
  • Factory noise level monitoring
  • Entertainment noise


The noise processor and logging module can be mounted on a wall or other suitable surface. The Noise Processor part continuously measures the sound levels in line with the noise measurement standards. The LiveNoise Terminal takes these measurements, stores them, and makes them available over your network. It also provides an HDMI output so you can display the sound levels on a computer monitor or HDMI television.

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.

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. Or they can do all three.

The Noise Processor is mounted to a wall using the mounting plate and four screws. The LiveNoise Terminal is mounted close by on just two screws.

An optional security bracket is available for the LiveNoise Terminal.

Wired Connections

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


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

Network Connection - WiFi or Wired 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 your noise reporting then the LiveNoise monitor uses the network connection to upload its measurements to the cloud server.

Wireless or Wired?

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

No Internet or High Security

The LiveNoise monitors can run with the Supervisor software on a local network with no Internet access. The software will not receive updates and we won't be able to provide remote support, but this is ideal where security systems limit access.


The LiveNoise Supervisor, Reporter and the online Web Reporter are included when you buy one or more LiveNoise Noise Monitors.

With the noise monitors connected to your network, you can chose how you want to deal with a live display and with long term reporting.

Local Network

Operating on your own WiFi/Ethernet network, with live sound levels sent to a Windows computer, you will use the following software:

Supervisor - Connects to all your noise monitors, showing the live sound levels, indicating any high noise level alarms and storing long term measurements.

Reporter - Using the measurements stored by Supervisor, this software generates long term noise reports: daily, weekly, monthly or custom periods.

Online Reporting

The noise monitors send all the noise measurements to our cloud server, from where the Web Reporter provides you with noise reports.
