Through experience in T&D applications, Amorim Cork Composites has implemented a priority 4 step system approach in analysis and treatment of “noisy” equipment. Our 4 step approach focuses on the need to control vibration before it reaches the tank structure (and therefore closer to the source of vibration), impeding that structural vibrations on the tank are transformed into airborne noise through the amplitude vibration of the tank walls acting as “speakers”. Typical noise reduction gains (cumulative gains) can also be observed when designing with ACC methodology (values based on project statistics).
