Class 1 Urban Noise Monitoring Terminal

SV 303

The SV 303 is a state-of-the-art Noise Monitoring Terminal designed to revolutionize urban noise management in smart cities. Meeting Class 1 standards as per IEC 61672-1:2013 and IEC 61260-1:2014, it guarantees exceptional accuracy in noise measurement. Its extensive LAeq measurement range, from 30 to 130 dB, ensures comprehensive coverage of urban soundscapes, capturing everything from the quiet of nighttime to the bustling activity of daytime. With its robust environmental resilience, the SV 303 operates effectively in temperatures from -20°C to 60°C and up to 95% humidity, making it suitable for diverse urban conditions.

The SV 303 is an affordable solution, making it ideal for multipoint noise monitoring across urban areas. By providing precise, real-time noise data, it enables city planners and policymakers to develop effective strategies to mitigate noise pollution, significantly improving the quality of life for residents. Its seamless integration with existing urban monitoring systems via USB and UART interfaces ensures adaptability and ease of deployment, establishing the SV 303 as an essential tool for creating quieter, healthier, and more livable cities.

What is urban noise?

Urban noise is the unwanted sound that permeates city environments, arising from sources like traffic, construction, industrial activities, and social gatherings. This pervasive noise can lead to numerous adverse effects on public health, including stress, sleep disturbances, and cardiovascular issues. Accurately monitoring urban noise with devices like the SV 303 is crucial because it provides reliable, real-time data for noise mapping that computer programs for noise mapping estimates cannot match. Real-world measurements capture the complexities of urban soundscapes, enabling precise assessments and informed decision-making to mitigate noise pollution and enhance urban living conditions.
