Abstract

A housing for receiving an electrically operated apparatus may include an inner housing part at least partially defining a housing interior. The inner housing part may include an inner passage opening. The housing may also include an outer housing part disposed on a side of the inner housing part facing away from the housing interior. The outer housing part may include an outer passage opening. The outer passage opening and the inner passage opening may at least partially define an acoustic duct for discharging airborne noise from the housing interior. The acoustic duct may be closed by a fluid-tight and airborne noise-permeable membrane. Further, the housing may include a porous member disposed within the acoustic duct configured to prevent an ignition breakthrough from the housing interior into an external environment outside of the outer housing part.
