Abstract
Computer system and method for determining frequencies of various components of a volume choke volume dampener to be attached to a compressor. The method includes determining a sound spectrum of a cavity of the compressor without attaching the dampener to the compressor; calculating an acoustic wavelength of the cavity; receiving a length of a proximal nozzle of the dampener; and calculating, based on the acoustic wavelength of the cavity and the length of the proximal nozzle of the dampener, multiple order frequencies associated with the proximal nozzle of the dampener and the cavity of the compressor, wherein the proximal nozzle of the dampener is proximal to the cavity of the compressor when the dampener is attached to the compressor.
