ABSTRACT

The paper presents measurement-calculation procedure, which may be use for estimation of increase in sound pressure level in dwellings radiated from vibrating partitions. The procedure is based on simultaneously twin channel measurements of vibration velocity on partitions and sound pressure level in dwellings. This method using properties of coherence function between has measuring signals. The calculations of the sound radiated from vibrating walls induced by vibro-acoustic sources (e.g. heavy traffic), which has been made by new measure-computational procedure directly from two channel measurements are presented as well.
