Abstract: Sound insulated stages are required for the production of sound pictures. Stages required to house a number of sets should be made acoustically dead. Stages consisting of only one set, such as scoring stages used for recording music, should have acoustical characteristics comparable to those of the concert hall. A scoring stage should not only have the proper reverberation time-frequency characteristic but, in addition, the wall and ceiling surfaces should be broken up in order to diffuse the sound. Measurements made on a stage where sound reflection from the floor was not prevented indicated the effect upon the frequency characteristic of a prominent first reflection. The use of more than one microphone for pick-up may lead to difficulties comparable to those experienced with stages having prominent reflection. Characteristic charts showing these effects are discussed in the paper. Rules, based upon the preliminary experimental work described, are given for avoiding poor quality where it is deemed necessary to use more than one microphone for pick-up.
