✦ Synopsis

Noise measurements were performed in 27 air-conditioned landscaped offices in the present investigation. From the measured equivalent sound pressure levels, percentile levels and noise level cumulative distributions, it is found that linear relationships exist between percentile levels and the equivalent sound pressure level. A new distribution function is proposed in the present study to describe the cumulative distribution as well as the probability density function of noise in air-conditioned landscaped offices. Higher order moments of the noise statistics can then be found. Results also enable the estimation of the above noise statistics from equivalent sound pressure levels and will be beneficial to the evaluation of existing offices and the setup of specifications for new commercial offices.
