Acoustic analysis is the study of various acoustic phenomena in piping and structural systems
that can result in acoustic induced vibration due to
acoustic exciters such as valves, ducts, and cavities (shallow or deep). Acoustic analysis is necessary to identify any potential sources of acoustic induced vibration in a given system and design a solution to mitigate the potential effects, typically failure through fatigue.
Acoustic resonance is the main phenomenon of concern, and it is induced by a gaseous fluid flow, typically but not limited
to air or steam. Issues that result from acoustic phenomena have been observed in power (nuclear, fossil), oil and gas and industrial systems. Acoustic resonance can lead to flow induced vibration. Different acoustic phenomena often present themselves in systems and go unnoticed until there is a failure in the system. Examples of acoustic phenomena are column resonance, Helmholtz resonance and trapped mode acoustics.
