A generalized description of community noises is studied to estimate its equivalent continuous sound pressure level L_<eq> on the basis of Weibull distribution. The goodness-of-fit is verified on the Weibull probability paper by the linearity of values of L_α which are exceeded α% of the time, and L_<eq> of a specified community noise is easily obtained through the parameter m and η of Weibull distribution. Differences between estimated and measured values of L_<eq> are found to be small and below 1. 0dB at most case of community noises, while parameters m and η exist within range of 1. 0<m<2. 5 and 5. 0<η<15. 0 respectively.
