The NoiseScout noise monitoring system is designed for unattended monitoring of noise levels in environments such as construction sites and airports. It is a professional system that provides a wide range of configuration options. These now include Plug & Play interfaces to a weather station and a GPS receiver.
NoiseScout can now provide up-to-the-minute weather and GPS data. Further, the WP30 microphone weather protection kit is now type-approved for vertical and horizontal sound incidence.
NoiseScout provides a complete solution
The primary task of the NoiseScout system is to record noise level and audio data measured by the XL2 Sound Level Meter. This data can be viewed live online in a web browser, and reports generated – even during the ongoing measurement.
Recording the relevant weather data
Precipitation and wind speed/direction can prejudice sound pressure levels when measured outdoors. NoiseScout thus records weather data, via the connected weather station, including atmospheric pressure, temperature, humidity, precipitation, wind speed and wind direction. The data recorded depends on which weather station is used. NoiseScout supports the following weather stations, connected via a USB port:
- Vaisala WXT532 (wind)
- Vaisala WXT533 (wind, rain)
- Vaisala WXT536 (wind, rain, pressure, temperature, humidity)
Remote unattended noise control
The XL2 Sound Level Meter can be controlled from afar thanks to NoiseScout. This is done through a web browser on your PC or mobile phone. You can also remotely hear what is causing noise limits to be exceeded. Noise level alarms are sent via email, including links to 10-second recordings of the loudest periods. This makes it convenient to identify when and why noise limits are being reached. All of these audio recordings, together with the level data, can be downloaded through NoiseScout in your web browser.
Automatic data management
The XL2 Sound Level Meter stores all measurement data locally on the device. This is directly available via a secure FTP connection. Alternatively, NoiseScout transfers the data to the cloud, managing the data automatically, and notifying users of important events via email.
Remove irrelevant events from your reports
The “Data Explorer” PC software is used to analyze and report on the data in detail. It graphs the level over time and includes an audio player, and the frequency spectrum. Users can mark any events, with a click of a mouse, for exclusion from the calculations. This filter determines a new overall level excluding extraneous sounds, rain or excessive wind.
These new features for NoiseScout are part of the new XL2 firmware V4.21. The update is available immediately and is free for all registered customers.
The new firmware is approved by the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany. In Austria, the approval was granted by the Federal Office for Metrology and Surveying (BEV) in Bregenz. In Switzerland, firmware V4.11 is approved.
