Noizam App, IDOM Audio Recorder and Data Collection Application.
Squeak and rattle (S&R) noise are important in-cabin sources of annoyance for occupants. Buzz, squeak and rattle are all noises produced by parts installed in such a way that they create annoying sounds. Buzz, squeak and rattle is thus caused by the relative motion between installed parts, which make them interact, sometimes only at certain environmental conditions. Chassis and structural design, material selection and controlled tolerance chains are all important elements to consider in order to avoid buzz, squeak and rattle noise. This must be specified in the design targets and design guidelines all the way from prototype to production and should constantly be measured with reliable measurement microphones. Noizam App identifies squeak and rattle type mechanical noise.
