It means that during the measurements the noise level 76.8 dB was exceeded in not more than 35% of the observation period. The cumulative density function for the exemplary data is presented in Figure on the right side.

    SVAN 979 User Manual - Appendixes APPENDIX E. REVERBERATION TIME CALCULATIONS E.1. I NTRODUCTION If an impulsive sound is generated in a room with reflecting boundaries, repeated reflections at the boundaries result in the rapid establishment of a more or less uniform sound field. This field then decays as the sound energy is absorbed by the bounding materials.
