A device and method for alleviating the effects of alternating or changing pneumatic pressures when sound is transmitted through an audio device into a substantially trapped volume to the tympanic membrane. Alternating or changing pneumatic pressures are partially or fully alleviated and allowed to remain as normal sound waves. The audio device and method could be any number of audio devices including ear buds, over-ear headphones or hearing aids. A passageway from the substantially trapped volume to an unsealed space at ambient pressure is blocked by a flexible compliant member.
