Abstract (en)
[origin: WO2020186330A1] A pneumatic system includes a fluidic switching module having an air passage and a vent in fluid communication with the air passage. The pneumatic system also includes a sound attenuator coupled to the fluidic switching module, the sound attenuator having a first chamber in fluid communication with the vent, a first orifice in fluid communication with the vent via the first chamber, a second chamber in fluid communication with the first chamber via the first orifice, and a second orifice in fluid communication with the first orifice via the second chamber.
