ACOUSTIC DATA RECORDING AND DATA ANALYSIS SYSTEMS

Noise measurement systems have, by necessity, undergone dramatic changes during the development years to keep pace with requirements. Current system designs provide calibrations traceable to NBS, increased sampling speeds, better resolution, more accurate and repeatable test results and meet the need of processing large amounts of data in short time periods. There have been improvements in the measurement of the environmental conditions affecting the noise and changes to the physical characteristics of test facilities to reduce ground reflections and minimize obstacles impeding the noise path.
