This paper addresses the fundamental mechanisms associated with Buzz, Squeak and Rattle (BSR) sounds and the analysis of their acoustic signatures. These sounds will be generated and analyzed individually with a conventional popular metric in the presence of typical background sound. Baseline computations of the background will be performed for comparison. This paper will present a look at the sensitivity of the current popular metrics ability to identify BSR specific sounds in the presence of background noise levels. This understanding of the measurement and quantification of the specific BSR sound signatures can be the basis for design target setting with respect to specific BSR phenomena. As well, this can lead to a better understanding of whether or not it is appropriate to quantify these phenomena together or if there is a need for a “Rattle Trap” metric, a “Buzz Trap” metric or a “Squeak Trap” metric.
