Frequency Band Averaged Data for Prediction of Structure-borne Sound Power from Mechanical Installations in Buildings

Structure-borne sound transmission is a more complicated process than airborne sound transmission, but practitioners seek methods of prediction for the former, which are as straightforward as for the latter. In this paper a description is given of measurement and calculation procedures where the source activity (the velocity of the source when resiliently supported) and the mobility, and receiv...

Sound transmission of cavity walls due to structure borne transmission via point and line connections.

The author has published equations for predicting the air borne sound transmission of double leaf cavity walls due to the structure borne sound transmission across the air cavity via (possibly resilient) line connections, but has never published the full derivation of these equations. The author also derived equations for the case when the connections are rigid point connections but has never u...
