| Abstract: | Adopts step wave method to measure the timeaverage sound level(equivalent continuous sound level) of the sound level meter.Comparing the experimental measure with theoretical analysis,the results show that experimental standard error is not more than 0.053 dB,the difference between the value of experimental measure and theoretical analysis is not more than 0.10 dB.It is seen that this method have a certain consistency and a high precision and could be used to measure Leq function of the sound level meter. |
