请问一下，标准有如下叙述： 0 v+ v" X1 d; `0 uFor music where the average sound pressure (long term LAeq,T) measured over the duration of + K8 o( f; C) Athe song is lower than the average produced by the programme simulation noise, the warning # [$ o) m( y& Z9 G) tdoes not need to be given as long as the average sound pressure of the song is below the ; P- D% X# h% Q' z |# m7 Z9 Dbasic limit of 85 dBA. In this case T becomes the duration of the song. 3 ~* \) Z8 n. l0 B y2 g1 M 3 y1 Q% N% D ~& e8 i W# }( XNOTE 4 Classical music typically has an average sound pressure (long term LAeq,T) which is much lower than the average T" X: i9 [4 y* h% @

programme simulation noise这个是用来测试声压标准信号。在任何的模式情况下都不能超过限定值。
