3.1
Time average sound pressure level time-averagedsoundpressurelevel
Lpeq, T
A continuous steady sound pressure level in the measurement time interval T, it measured the sound changes over time with the same mean-square sound pressure, also known as
Equivalent sound pressure level.
Time average sound pressure level according to equation (1).
Lpeq, T = 10l [g 1T∫
100.1Lp (t) d] t

Where.
T --- measurement interval in seconds (s);
p --- instantaneous sound pressure units Pa (Pa);
p0 --- reference sound pressure (20μPa).
Note. The average time for the A-weighted sound pressure level is generally used LAeq, T represents.
