An example urine suction device suitable for extracting urine from a urine collection device is disclosed. The suction device can include a motor, a pump driven by the motor, a conduit, and an acoustic silencer. The pump can extract urine from a urine collection device. The acoustic silencer can be in fluid communication with the pump and conduit. The acoustic silencer can attenuate or reduce one or more acoustic waves generated by the pump and/or the motor. One or more components or structures within the acoustic silencer can at least partially attenuate the acoustic waves as they propagate along a non-linear airflow path defined by the acoustic silencer.
