Frequency responses and RTA measurement results of cinema screen systems are presented for a small selection of cinemas sizes and shapes in Australia. Measurements have been made using time gated techniques (MLSSA) and the traditional pink noise Real Time Analyser (RTA) process with a microphone array. Results from these methods will be compared with the manufacturer’s quasi anechoic measurements, and probable reasons for the differences will be discussed.
