-Sound level
-.1 Loudspeaker reproduction
-When using a wanted signal of high peak level, the sound level should be measured with a sound level meter with no weighting and the “slow” time constant standardized by the IEC (Publication 123). For other signals, and for measuring room noise, the level should be measured with a sound level meter with weighting A and the “slow” time constant standardized by the IEC (Publication 123). For measurement of the sound level of a programme sequence in the special conditions of the test and at a given position in the listening room, the sound level will be taken by definition as equal to the maximum value shown by the sound level meter during each sequence. **In case of assessments of high-quality high-level signals, a listening sound level of 80 to 90 dB should be used.**
