Correctly identifying and recording noise is continually being made simpler with the proliferation of highly advanced noise meters and recording equipment. Noise measurement software applications are even finding their way onto our mobile phones, with applications for frequency analysis, spectrum analysis and noise level being available for less than $10USD.
With the easy availability of equipment to measure and record noise there is often an avalanche of data which can make it difficult to sort out what is a problem and what is not a problem. Correct interpretation of recordings and measurements made on this proliferation of devices requires trained technical expertise to ensure that equipment is correctly calibrated so that meaningful information about levels is obtained, and experience to ensure that the interpretation is not miss-leading.
