A simple method to measure structure-borne sound transmission is described. Measurement is made of the level difference in the acceleration between two structural elements using a plastic headed hammer as a noise source. The method is at least as accurate as conventional measurements made under stea

The aim of the work presented in this paper is to test, in the field, a method for the prediction of structure-borne sound emission from resiliently mounted machines. The vibrational power injected into the machine seating is the structure-borne equivalent of the (airborne) sound power. Initially, a

The paper deals with methods of independently characterizing sources of structure-borne sound. The concept of mirror power is introduced, which is the power delivered by a vibration source when connected to a passive receiver structure that is a mirror image of itself. A second quantity, the charact

Structural waves in a cylindrical shell can be decomposed into di!erent circumferential modes. The energies carried by these modes usually need to be quanti"ed and ranked for the purposes of noise and vibration control. In this paper, a theoretical basis is outlined for a method to measure the energ

For the characterization of structure-borne sound sources with multi-point or continuous interfaces, the concept of source descriptor and coupling function can be reformulated by incorporating the interface mobilities. The applicability of this approach, however, depends on the admissibility of negl

Differences among readings on different sound level meters when measuring the same signal have been studied with the object of specifying the measuring accuracy in in situ measurements. Three sound level meters of different origins have been used, and five kinds of noises have been measured in five
