BSR Checker provides means to detect stick-slip noise on a vehicle assembly. The ergonomic design allows you to press down the part under test with sensitive thumb-down design while an embedded load cell records the applied force and an embedded microphone listens and analyses generated BSR signal. BSRTools is a set of different software and hardware tools, each focusing on measuring, evaluating, and identifying various stick-slip noise.
