ABSTRACT
This chapter discusses the basic needs in control rooms. It explains the special requirements of studio monitor systems. The chapter examines the loudspeaker responses in the pressure zone. Music recording also frequently tends to take place at higher levels than will be used for most domestic reproduction or standard listening tests, which can further alter the balance of compromises. In the late 1970s, Don and Carolyn Davis were keenly investigating many acoustic and psychoacoustic phenomena with the then newly developed Time Energy Frequency/Time Delay Spectrometry (TEF/TDS) measurement systems. In 1981, in Tokyo, Sam Toyoshima was designing studios for some of the major recording companies, and these rooms were beginning to be noticed in Europe and the USA. In 1986, he presented a paper on control room acoustic design. In the top-level control rooms it is general practice to build the monitor loudspeakers into the front walls.
