The SV200A noise monitoring station is engineered to comply with UK noise regulations and environmental monitoring standards. Certified as a Class 1 Sound Level Meter by the German Physikalisch-Technische Bundesanstalt (PTB), the SV200A exemplifies accuracy and reliability, essential for meeting the demanding criteria of UK noise compliance.
This station performs real-time frequency analysis in 1/1 and 1/3 octave bands and captures audio signals for in-depth noise source identification. This functionality is in line with the UK's rigorous noise moniotring and analysis requirements, guaranteeing not only precision but also extensive data detail.
Equipped with advanced connectivity features, including a 4G modem, WLAN, and LAN, the SV200A ensures uninterrupted data transfer. This is critical for the UK’s focus on accessible and transparent environmental monitoring, where the availability and accuracy of data are crucial.
The SV200A’s noise directivity detection is particularly crucial in the UK’s dense urban and industrial environments, where accurately identifying the source of noise is often required by regulation. The station’s integrated microphones excel in pinpointing primary noise sources, providing insights into their positions in both vertical and horizontal dimensions. This feature is essential for scenarios requiring the identification of specific noise sources for UK regulatory adherence or for isolating and omitting irrelevant noise events.
The station employs an advanced sound intensity technique, utilizing four strategically positioned microphones, to ascertain the direction of the primary noise source. This method proves invaluable across the UK’s varied environmental contexts, from vibrant city environments to active industrial areas, aiding in improved urban planning, effective noise control, and enhanced public health initiatives.
