Understand The Physics of Open-Ear Directional Audio

simon — Wed, 10 Jun 2026 01:08:15 +0000

In the landscape of personal audio, the “Open-Ear” category is dominated by a struggle against a fundamental law of physics: the Inverse Square Law. Usually, to hear audio clearly, a transducer must be coupled to the ear canal (IEMs) or sealed against the pinna (Over-ears) to prevent sound energy from dissipating into the atmosphere. Open-ear […]
