Environmental Noise Control, Inc. offers a variety of sound and vibration level surveys, including ambient sound level measurements, operational sound level measurements, and noise analysis sound level measurements.
Ambient sound & vibration level measurements are taken before drilling activity, compressor operations, or any other oil and gas-related activity begins at a proposed location to establish non-operational, or baseline, ambient sound levels. Many noise ordinances use the measured ambient sound levels to calculate allowable operational sound levels. For oil & gas operations that have already begun, ENC offers operational sound & vibration level measurements.
Operational sound and vibration measurements can be used to verify compliance with allowable operational levels and demonstrate the noise impact of the oil and gas operations on the surrounding area. When oil & gas drilling sites, compressor stations, or pipeline excavation operations comply with local ordinances & noise complaints are still streaming in, ENC offers various noise analysis services beyond simple overall dBA sound level measurements. Using a combination of on-site audio recordings, detailed sound level measurements, and the PULSE analysis platform software developed by BrÅ±el & Kjær, ENC can perform 1/1 & 1/3 octave band frequency analysis & detailed 1/N octave Fast Fourier Transform (FFT) and Constant Percentage Band (CPB) frequency analysis.
Noise source identification can be challenging on oil and gas drill sites, compressor stations, or pipeline excavation sites because of the large number of noise-generating equipment associated with such operations. Using detailed frequency analysis, ENC can measure the frequency spectrum, or “noise signature,” of each piece of equipment and compare it with the frequency spectrum at the location of the noise complaint to determine the offending piece of equipment.
The frequency spectrums can then select specialized noise mitigation material designed to block and absorb frequencies particular to the noise-generating equipment.
