All-in-one noise monitoring station

28 August 2018

Svantek's SV 200A all-in-one noise monitoring station has four built-in microphones for noise directivity detection. The new instrument enables identification of dominant noise sources, providing information about their location, both in vertical and horizontal directions.

The company’s SV 200A is a Class 1 sound level meter integrated with wireless communication via 3G, LAN, Wireless LAN and Bluetooth. The measurement of directionality gives the opportunity to indicate the dominant source of noise in the area of measurement, the exclusion of unwanted events or to identify aeroplane flightpaths.

The noise monitoring station has four additional microphones on the sides of the housing which use the sound intensity technique to detect the direction of a dominant noise source both in the vertical and horizontal axes. The Leq distribution in angle sectors is saved as the time-history and can be used for data filtering and reporting.

The SV 200A noise monitoring station can perform a real-time frequency analysis on 1/1 and 1/3 octave bands and save it as time history data. Additionally it can record the audio signal for noise sources recognition and data recalculation.

The advanced alarms function can send email and SMS notifications triggered by threshold level conditions. Status alarms are also available. 

The 3G modem, WLAN and LAN provide fast data transfer over the Internet to a PC with standard Internet connectivity.

Adhering to ISO 1996-2 requirements, the SV 200A uses an electrostatic actuator to perform a periodic system check. 

A large windscreen is highly efficient reducing wind noise effects even at high wind speeds. Metal spikes protect the station against birds. The weatherproof housing protects against extreme weather conditions while fulfilling Class 1 accuracy.

The accurate GPS module provides information on location as well as measurement time synchronisation.

The SV 200A has an internal Li-Ion battery and interface for direct solar panel connection. A waterproof mains adapter for charging the battery and powering the station is also included.

Bluetooth and Wireless LAN provide an access point for easy configuration with the SvanNET App. This is an advanced server solution supporting remote connection with SV 200A. The SvanNET allows usage of all types of SIM cards with the SV 200A modem regardless of whether there is public or private IP. 

The connection over SvanNet allows the use of a web browser to watch real time measurement results, manually download files and reconfigure the station, as well as download files and configure the station.
