How is compression ratio determined
WebThe ratio answers the question — for every dB the sound goes above the threshold, how many dB should the compressor let through? Let’s say you set up a compressor with a … WebThe rapid compression or expansion of a gas in a plastic syringe is a poor approximation of an adiabatic process. Heat exchange with the walls of the syringe brings the gas to equilibrium in an amount of time that is not significantly greater than the length of the compression or expansion itself. Despite this limitation, it is still possible to measure the …
