Overview

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 noise processor has a small display that shows the current sound level in dB(A).

The LiveNoise Terminal takes these measurements, stores them, and sends them to our cloud server. It communicates continuously with the server to provide real-time noise levels, long-term noise measurements and high-noise alarms. You can use a web browser to access your LiveNoise Account to view these live levels or to generate daily, weekly or monthly reports.

The LiveNoise Terminal just needs power (a power adapter is included) and access to the Internet through your network. It can connect to your network using Wi-Fi or a wired Ethernet connection. If, for any reason, the network connection is lost the LiveNoise Terminal has sufficient memory to operate alone for up to three years. Once the Internet connection returns the measurements are automatically sent to the cloud server so there are no gaps in your data.

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.

Network Connection - WiFi or Wired Ethernet

The LiveNoise Terminal communicates with our cloud server over your existing network. It sends the noise measurements every minute so you can produce up to date reports. If anybody on the account is viewing live data then it also sends the sound levels every second. It uses a data efficient method so the bandwidth use is minimal. You won't notice these units on your network.

As the measurements are on a cloud server there is no software to install on your computer. You can access the live sound levels and the long term reports from anywhere using a web browser.

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).

Viewing Live Sound Levels

To view the live sound levels from any connected noise monitors you use your web browser to log in to your LiveNoise account.

You will be presented with the sound level at each location, updating every second and displayed as numbers, charts or a mixture of the two.

The background is a simple image (JPG format), which you can upload to your account. It can be a picture of the location, floor plan, satellite image, whatever you choose. Alternatively, you can ignore the background and just have the sound level or chart as a large, full-screen display.

Warnings and Alarms

If you have alarm trigger levels set up then the chart or numbers will indicate a warning level in yellow and an alarm level in red. If the level stays above the alarm level for the preset period of time then the window will flash red to attract attention.

Noise Reports

Each remote noise monitor calculates the usual noise parameters over periods of 5, 10, 15, 30 and 60 minutes. These measurements are sent to the cloud server as soon as they are available so you can create noise reports using a web browser.

Your noise reports can be daily, weekly, monthly or over any custom period you choose. The reports show the sound levels in a chart or in a table.

Report Parameters

The reports include many parameters, measured with both "A" and "C" frequency weightings and, where applicable, Fast and Slow time response. This includes the Leq (average sound level), Lmin and Lmax, as well as the statistical parameters L5, L10, L50, L90, L95 and L99. The charts also indicate the number of alarms detected in each period.

Report Generation

To generate a report you select which noise monitors you want to include, the time period you want to see (daily, weekly, monthly or custom) and the measurement period to use (5, 10, 15, 30 or 60 minutes). Your choices are remembered so you don't have to select everything each time.

You can leave the report on-screen and it will update automatically whenever new measurements are available.

Exporting Reports

The reports you generate in your browser can be exported to PDF or CSV files. A PDF export is useful for printing, emailing or just for your records. The CSV export produces a table of results that can be imported to a spreadsheet or other similar program.
