Stephen Ambrose describes how sealing a speaker in the ear canal boosts sound pressures.
Lead author and audio pioneer Stephen Ambrose of Asius Technologies describes the reserach from two papers presented at the 130th Audio Engineering Society convention in London. The papers describe how sealing a speaker in the ear canal dramatically boosts sound pressures and how a modified ear-tip can help alleviate, or even eliminate, that effect.
