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

作者：Mohammad Al Zubi

来源：[J].Open Journal of Acoustics, 2018, Vol.08 (02), pp.13-22Scientific Research Publishing

摘要：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 sou...
