"NPL is the UK’s National Measurement Institute, and one of its responsibilities is to develop and apply the most accurate measurement standards. Existing acoustic measurement techniques, used in the test and measurement of acoustic products such as transducers and loudspeakers, make use of microphones to map the soundfield around the device being measured, its directivity and dispersion pattern. However, measurements have to be made at many points to create an accurate picture of how sound propagates around the device, and the microphone has to be moved many times. Moreover, the presence of the microphone can itself distort the dispersion pattern being measured..."
