Abstract: A method of simulating attenuation of an impulse signal of a reciprocating compressor includes providing a reciprocating compressor that includes a crank connected to a motor, a compression chamber, a reciprocating piston positioned in the compression chamber, and a connecting rod attached to the piston. The method also includes connecting the connecting rod to the crank with a first crank pin, mounting at least one transducer on the reciprocating compressor, running the compressor, measuring a first impulse signal with the at least one transducer, replacing the first crank pin with a second crank pin, the second crank pin having a diameter different than the diameter of the first crank pin, running the compressor, measuring a second impulse signal with the at least one transducer, and comparing the first impulse signal to the second impulse to determine an amount of attenuation between the first and second impulse signals.
