BSR Observer is a software released from BSRTools series, designed to measure and represent the position of noises especially Buzz, Squeak, and Rattle (referred to BSR) which occur in the interior as well as exterior of a vehicle. It offers a real-time window demonstrating accelerometer data logger, quantification of noise sources, and noise cancellation (Noise Gate) in real-time for the data measured through DAQ and accelerometers. The recorded data can be viewed as localization of noise source analysis of Root Mean Square (RMS) and Time-frequency, and Displacement conversion. BSRTools is a set of different software and hardware tools, each focusing on measuring, evaluating, and identifying various aspects of Buzz, Squeak, and Rattle.
