Wind Turbine Noise Monitoring

Larson Davis Noise Monitoring Systems provide full capability for collecting the noise, wind speed, and wind direction data needed for wind farm noise analysis. Rapidly deploy any of our systems and include real-time communication, GPS logging, weather data acquisition, and the data analysis tools as required. With Larson Davis you can own your monitoring system and own your noise management plan for effective interaction with the community and regulatory agencies.

Wind energy is a renewable energy source that is being harnessed globally to reduce our dependence on fossil fuels and the associated impact on our environment. However, the environmental impact of the turbine noise and the blade pass noise is a concern that is carefully monitored and generally regulated. It is very important to be able to acquire accurate acoustical data for analysis, noise impact predictions, and regulatory compliance.

Wind turbine noise monitoring is a very valuable tool to manage a wind farm’s relationship with the community and with the local regulatory organizations.

Applications

• Wind Turbine Noise Monitoring

Noise Monitoring

Larson Davis offers a family of noise monitoring systems with various power, communication, and sound recording options that can be implemented to suit the needs of any wind farm operation. Permanent monitoring systems can be used to acquire data 24/7 and make operational adjustments as needed based upon fluid regulatory requirements, community feedback, or local regulations. Our portable monitoring systems can be deployed rapidly for specific studies over shorter periods of time and can be easily moved from one data acquisition site to another. They come with weather resistant enclosures and outdoor microphone options. Our hand held sound level meters can be used for on-site evaluation and logging of noise levels.

Larson Davis permanent, portable, or attended monitoring system have options that are critical for successful wind noise monitoring, including:

• Weather data acquisition (including wind speed, wind direction, temperature, humidity, and rain fall)
• GPS positioning to log survey locations
• Exceedance detection to determine noise events from sources other than wind turbines
• Automatic storage of data to USB flash drive
• Web publishing, emails/SMS alerts, and remote communication
• Complete set of metrics (including octave and third octave filters to 6.3 Hz, frequency weightings, time weightings, Ln percentiles, and community noise calculations: Lden & CNEL, and more)
• Tonality metric for calculating annoyance of tones
