Time-interval equivalent-continous sound level

p(t) – measured sound pressure [Pa]
p0- reference sound pressure 20uPa
 


Sound exposure level LAE (ASEL)

ASEL is continous sound level containing the same energy as measured level during t2-t1 time, but last for
a one second.
 


Normalized equivalent continous A-weighted sound pressure level to a nominal 8h working day, LAEP,d

TE – noise exposure time ,
