Audio glasses have built-in speakers along their side arms and earpieces. The distance between the speakers and the ear canal depends on the user’s head size which can vary across individuals. It is therefore difficult to deliver a consistent audio performance across people with varying head sizes. This disclosure describes techniques that adapt the total sound energy incident upon the ear canal so that a consistent audio performance is delivered regardless of head size. The techniques work by varying the number of active sound ports, by incorporating a speaker mesh of variable sound resistivity, and by generating a uniform sound pressure at various speaker-to-ear-canal distances.
