ABSTRACT:
An aromatherapy air pump is damped and largely isolated against acoustic and mechanical transmission of vibrations in three dimensions by a combination of containment within multiple, nested housings and standoffs provided by elastomeric supports having anisotropic geometry. An elastomeric liner as well as unstable legs, physical separations, and hermetic seals combine to provide sound reduction for noise and vibration emanating from the pump and its drive motor.
