A refrigerating compressor includes a compressing element and a hermetic container accommodating the compressing element, which includes a compressing chamber where refrigerant gas is compressed, and a suction muffler ( 118 ) having a sound deadening space ( 119 ) and communicating with the compressing chamber. The suction muffler ( 118 ) includes a tail tube ( 121 ) having a first end open into the hermetic container and a second end open into the sound deadening space ( 119 ), and a resonating chamber ( 122 ) formed attached to the tail tube ( 121 ) and having a resonance frequency substantially agreeing with a specific resonance frequency of the hermetic container. This structure allows the resonating chamber ( 122 ) to deaden the noises coming from vibration sounds of a suction valve or ripple sounds of refrigerant gas.
