  • TITLE: Measurement of Sound Pressure Levels in Anechoic Chamber and a Noisy Environment Experimentally

    AUTHORS: Mohammad Al Zubi

    KEYWORDS: Sound Pressure Level, Anechoic Chamber, Free Field, Noisy Environment, Sound Extraction

    JOURNAL NAME: Open Journal of Acoustics, Vol.8 No.2, April 30, 2018

    ABSTRACT: In real life, when a noise problem occurs, it is important to identify the cause and measure the noise of the source, since it may affect human beings or other constructions due to vibration generated from noise, so it is necessary to determine the noise related to a specific source like a machine in the presence of other sources which is a very important approach in noise control engineering. In this article a full experiment was executed to measure the sound pressure levels of various sources (stationary and non-stationary), in both an anechoic chamber and a non-ideal noisy environment. The sound pressure level was extracted for different sources and compared for both ideal and non-ideal environment. The results showed that acoustical free field of the space is the best field to do measurements to avoid reflection, on the other hand the difference between the source and the background should be more than 3 dB to get better results.
