Overview

Noise Processor & LiveNoise Module

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 Module takes these measurements, stores them, and sends them to the LiveNoise server so you can view them using a web browser.

LiveNoise System

The noise monitor communicates continuously with the LiveNoise Server, sending real-time noise levels, long-term stored noise measurements and high-noise alarms. Using a web browser you can view the real-time noise levels as well as the long-term noise reports.

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.

Installation

Mounting

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.

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 LN2-320 noise monitor communicates with the LiveNoise server to provide a real-time display of sound levels and for long-term noise measurement storage. The LN2-320 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.
