Overview

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 server over your network.

LiveNoise System

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

A system can consist of one or more LiveNoise enabled noise monitors. They connect to your local area network using either WiFi or a wired Ethernet connection and send all measurements to our LiveNoise server.

Installation

Mounting

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.

Connection

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

Power

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

Network Connection - WiFi or Ethernet

The LN2-EAR noise monitor communicates with the LiveNoise server to provide a real-time display of sound levels and for long-term noise measurement storage. The LN2-EAR noise monitor just needs access to the Internet to send the live and historic noise measurements.

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.
