Is a set of test equipment to measure the noise level, it is very necessary especially for industrial environments, for example in the aviation industry where the surrounding environment must be tested for sound noise level or the resulting sound pressure to determine its effect on the surrounding environment.
Sound Level Meter currently has international standardization with EC 61672: 2003 standard. There are several factors that influence the measurement using sound level meters, this makes the measured sound waves may not be the same as the actual sound wave intensity.
