โœฆ Synopsis

Some typical data are given for structure-borne sound excited by train traffic. They show that the dominant frequency range is between 40 Hz and 100 Hz, where the wheel/track resonance lies. Three possible generating mechanisms are qualitatively described; their dependence on the most important parameters is discussed. Only a few remarks are made on structure-borne sound propagation in the ground, and nothing is said about building vibrations. These phenomena depend very strongly on details (inhomogeneities, special constructions, etc.) that are extremely hard to specify. Therefore reliable predictions are very difficult unless a large amount of empirical data is available.

Noise from machinery in buildings is caused by a mixture of air-borne and structure-borne sound. Relations are given for the estimation of sound levels in rooms due to air-borne and structure-borne sound transmission. For air-borne noise well-known quantities can be used to describe the source stren

A method for calculating the structure-borne sound power emission through the resilient mounts of machines is investigated by comparing calculated power with in situ measured power for a range of fans on concrete floors. The structure-borne sound power is the structure-borne equivalent of the airbor
