AES-X218 Measurement and calibration of sound systems in rooms has been initiated and assigned to AESSC Working Group SC-04-08
This project seeks to document relevant parameters affecting the audience experience of a sound system in a generalized room, and identify appropriate objective methods of measurements to quantify them. The intent is to identify tools and procedures for a technician to measure the performance of a loudspeaker system in a room, and then support accurate and reliable calibration of this system to a specified performance. The output intent is an Information Document.
Measurement of sound systems in rooms, including but not limited to cinema B-chains, currently relies on empirical measurement techniques developed in the 1970s. Modern methods and equipment should offer simpler and more accurate ways to calibrate rooms with greater precision. This project will review the parameters that affect the audience experience in these rooms, and the objective methods of measurement necessary to quantify them. This will provide a basis for more detailed standardization for measurements and calibration protocols for controllable parameters.
