What do noise measurement metrics mean?
Thread Content
The main measurement parameters for noise are Leq,t, LFp, LSp, Leq,t, Lpeak, Leq,T, SEL, Lex8h, LAVG, TWA, DOSE, L5, L10, L50, L90, L95, and SD. What does it mean by having a friend provide guidance?
Leq: Equivalent continuous sound pressure level. LAeq: Equivalent continuous sound pressure level using the current frequency weighting A. LBeq: Equivalent continuous sound pressure level using the current frequency weighting B. LCeq: Equivalent continuous sound pressure level using the current frequency weighting C. LZeq: Equivalent continuous sound pressure level using the current frequency weighting Z. Weighting refers to the artificial adjustment of the current sound pressure level; weighting A is used to simulate the auditory characteristics of the human ear, while weights B and C are less commonly used. Weighting Z represents no weighting at all
