Octave band technique for noise measurement at the source, path, and receiver of gas turbines in oil and gas facilities
Noise measurement is essential for industrial usage. However, further attention to preventing
noise pollution is needed, especially when working with equipment generating a high noise
level, such as gas turbines. This study aims to determine the best way to perform noise
measurement and analyze the octave band frequency generated by noise pollution caused
by gas turbine equipment. Data from site measurements show that the gas turbines produce
more than 85 dB of noise with a Z-weighted measurement. A noise measuring investigation
was conducted to obtain the data for the 1/3 octave band. A frequency-domain was used to
comprehend the properties of the noise measurement frequency band. The frequency band
was classified into three different zones called low, medium, and high frequency, which is
useful in noise measurement analysis to identify a viable solution to reduce the noise. On�site sampling was performed at the source, path, and receiver of three separate gas turbine
locations within oil and gas operations. The 1/3 octave band data collection results at the
sound source, path, and receiver demonstrate the noise level distribution at the perimeter
of gas turbine installations in the low and medium frequency ranges. Most of the high
noise frequency range is between 250 Hz and 2 kHz for source, path, and receiver. All
acquired values are compared to the Department of Safety and Health (Occupational Safety
and Health (Noise Exposure) Regulations
2019 in Malaysia. As a result, oil and gas
service operators can monitor and take
countermeasures to limit noise exposure at
oil and gas facilities
