Sound attenuating liquid-gas separation apparatus includes nested elements which are tuned to abate noise in general and at predetermined frequencies in particular in a screw compressor assembly. The apparatus includes a helical flow path defined internal of an outer shell. The shell is selectively perforated at its downstream end to allow for the egress of separate oil from it. The apparatus includes a columnar, open-ended cylindrical member internal of the outer separator shell and a discharge conduit which penetrates both the separator shell and the open end of the columnar cylindrical member disposed within the shell to create the nesting which both contributes to the oil separation proces and abates noise. By selectively dimensioning and therefore "tuning" the nested members in accordance with the characteristics of the particular compressor with which they are used, compressor assembly noise abatement at predetermined frequencies is accomplished.
