Base Line Noise Monitoring - Windfarms
A baseline noise survey carried out as per requirements in ETSU-R-97.
The baseline noise measurements were made with Precision Integrating Sound Level Meters. The sound level meters comply with the type 1 standard in BS5969:1981. These have to be outdoor noise monitors with weatherproof microphones and logging kits.
Measuring the LAeq, etc. plus LA90 10 min
The sound level meters to be left at the measurement positions for a period of time.
The meters are programmed to measure a number of statistical noise indices, including the LA90, together with the maximum and minimum levels and the LAeq (the Equivalent Continuous A-Weighted Sound Pressure Level) over consecutive 10 minute periods. Results are to be synchronised to wind speed measurements at an on-site anemometry mast to allow for later correlation between the two.
Noise predictions are to be carried out using International Standard ISO 9613, Acoustics – Attenuation of Sound During Propagation Outdoors [Part 2]. (and using CadnaA software).
EURO environmental services have skilled and trained technicians who can carry out this monitoring for a high standard level.
