SJ/T 11522-2015 The main performance testing methods for cinema speaker systems are: 1. Sound pressure level measurement: This method measures the sound pressure level at different locations in the auditorium using a sound level meter. 2. Frequency response measurement: This method measures the frequency response of the speaker system by recording the sound pressure at different frequencies using a sound level meter and analyzing the data. 3. Stereo imaging: This method measures the ability of the speaker system to create a three-dimensional sound field by recording the sound pressure and a
