PEI Vibration Monitoring
The ATB test bed characterizes the acoustic performance of a muffler measuring the Transmission Loss (TL). It can be done on aspiration and exhaust systems of vehicles.
The TL is an intrinsic feature of a muffler that describes how much the muffler can decrees the intensity of a waveform energy that goes through it. Depending on the design of the muffler, the attenuation of the noise is a function of frequency, therefore the TL is a key indicator for a correct design of the muffler.
Furthermore, the ATB test bed has a feature to estimate the noise that a specific muffler would generate if installed on an engine, with known excitations from experimental test analysis or models.
