The SV 200A noise monitoring station is the most advanced of its kind with built-in microphones for direct noise detection for a total of five microphones. This revolutionary solution allows the identification of the dominant noise sources providing information about their location in both vertical and horizontal directions. In practice, the measurement of directionality provides the opportunity to indicate the dominant noise source in the measurement area or to exclude undesired events. There are four additional microphones located on the sides of the housing that use the sound intensity technique to detect the direction of a dominant noise source on both the vertical and the horizontal beams. The station can perform a real-time frequency analysis in bands (1/1) and thirds (1/3) of octave, as well as record the audio signal for the identification of noise sources during the measurement and to be able to apply recalculation of data. Its integrated 4G modem allows the transmission of data in real time to a dedicated server on the cloud with access through the SvanNET platform, as well as its Bluetooth interface allows connection to the station through the smartphone to check its status. The SV 200A features an electrostatic actuator that allows you to check the microphone and the operation of the included system remotely. Its design allows it to comply with the requirements of ISO 1996 and become an advanced noise monitoring station in the world market. The SV 200A is the ideal option for environmental monitoring for noise control, evaluation, and modeling. Ideal for environmental measurements, monitoring in constructions, preparation of noise maps, monitoring of industrial noise, assessment of environmental impacts, compliance with environmental management plans, noise control in neighboring areas, among other functions.
