Are there any standard methods to calculate near field sound pressure levels from vib/acc measurements?
The application I am looking at is an exahust duct (HRSG or SCR) from a combustion turbine generator. Need to seperate out the duct noise from the balance of plant noise - this was one...
Is anyone aware of any studies conducted to determine the effect of wind direction on far field noise levels (distances greater than 1,000 feet from the wind turbine generator). Generally, I would expect downwind to be slighly louder than upwind, but would like to confirm with published...
