- AV-A-10 Speech Reinforcement Speaker Polarity Speech reinforcement systems shall be polarized such that a positive acoustic pressure on a microphone results in a positive acoustic pressure at all loudspeakers.
- AV-A-11 Alignment of Multiple Audio Sources Calibrate audio system inputs so there is zero or minimal difference between any input signal level.
- AV-A-12 Audio Buzz and Rattles There shall be no audible vibration caused by improper mechanical installation. Perform buzzes and rattles test, using continuous sweep signal (from generator or test CD) pass/ fail result or which device at what frequencies.
- AV-A-13 Audio System Gain Before Feedback The speech reinforcement system shall be stable and operate without feedback.
- AV-A-14 Conferencing System Microphone Sensitivity and Gain Structure Alignment For conference systems, adjust microphone input gain to demonstrate that "standard talker," positioned at each talker position in the room, produces a 0 dBu level at the output of the output bus of the audio conference DSP device. Verify signal levels for both transmit and receive using normal speech.
- AV-A-15 Audio System Equalization for Speech Intelligibility Equalizers shall be adjusted for best intelligibility, and in accordance with the preferred acoustic level response curves. For systems with equalizers, document the “house curve” before equalization, as well as after the equalizers have been tuned, with and without microphone input filters. If requested by the Consultant, produce this documentation for systems without equalizers, as this test may apply to the preamp filter settings in cases where intelligibility can be improved.
