Abstract: A proposal of the Nordisk Film/TV Union (NFTU), document 1069-1969, is discussed in great detail. This document refers to the measurement of acoustic response in cinema theaters for optical 35-mm soundtracks. The instructions, procedures and equipment this proposal offers for consideration are described at length, for the benefit of the service engineer for whom this type of measurement may constitute a new field of activity. Also, the work carried out simultaneously in other countries and by ISO is described. Reference is made to test films and further developments of instrumentation in the recent past. Mention is made of the new possibilities opened up by an ISO Draft Proposal, calling for an “Y”-curve to cover films currently in production or exploitation, and for a “X”-curve for such new systems as the Dolby SVA and the Hue-Modulated Photographic Color Soundtrack. A hope for further research regarding roll-off or no roll-off is also expressed.
