Why are squeaks and rattles considered an annoyance?
Squeaks and rattles are perceived by customers as an annoyance and/or a lack of quality in a vehicle. In today’s cost competitive environment, engineers must be sure to prevent all squeak and rattle issues that would be perceived by customers as an annoyance, without spending money on those issues only detected by the experts.
What causes a rattle, Buzz and squeak noise?
More precisely, buzz originates from the structure or part itself, squeak is caused by friction between parts, and rattle is caused by impact. Buzz, squeak and rattle is a well-known source of extreme annoyance to the driver and the reason for many customer complaints and is an important part of the overall perception of a vehicle.
What’s the difference between a rattle and a squeak?
Squeak is one unexpected unacceptable noise, and rattle is another noise resulting from an impact/contact event between two hard surfaces. It has been shown that a comprehensive postprocessing of experimental results helps to reliably detect and identify friction-induced sounds that may be masked by unavoidable background noise.
What causes a car cover to squeak and rattle?
The stick-slip risk is the higher, the more readily the material deforms. Cover materials with high static friction are subject to a higher stick-slip risk; back-filling—which increases deformation—almost invariably leads to squeaking.
How to avoid problems with Squeak and rattle?
To avoid problems with squeak and rattle, the parts must be sufficiently attached so that no relative motion can occur. The stiffness of the attachment area is an important parameter to consider. High stiffness gives high first resonant frequency and avoids resonance with the major engine idle frequencies and road excitation, which is good for
What does Buzz Squeak and rattle stand for?
Buzz, squeak, and rattle (BSR) is the automotive industry term for the audible engineering challenges faced by all vehicle and component engineers. Minimizing BSR is of paramount i read full description

Why does my car Squeak and Rattle all the time?
Squeak and rattle is a high frequency audible phenomenon resulting from two distinct forms of Noise, those caused by elements in friction under forced road surface excitation and those caused by loose or overly flexible elements with the potential for impact with other elements.
