Estimation of equivalent sound pressure levels of community noise and road traffic noise

Abstract

This study was aimed at making sure usefulness of assumption of Weibull distribution or Rayleigh distribution for estimating L_eq of community noise and road traffic noise from noise levels in L₅, L₅₀ and L₉₅. The results showed that Weibull distribution was very useful to estimate L_eq except few cases like the exponential distribution of noise levels and that Rayleigh distribution was also useful with permitting errors of about 1.5 dB (A) except such cases as distributions of noise levels were largely skewed to lower levels or higher levels.
