1. A head-mounted wearable device comprising:
a front frame;
a first temple connected to the front frame, wherein the first temple includes a first exterior wall and a first internal volume;
a first transducer within the first internal volume, wherein a first single layer of material that includes the first exterior wall separates the first transducer from an exterior of the head-mounted wearable device, and wherein the first transducer separates the first internal volume into a first portion on a first side of the first transducer and a second portion on a second side of the first transducer;
a first opening in the first single layer of material that permits passage of air between the first portion of the first internal volume and the exterior of the head-mounted wearable device;
a second opening in the first single layer of material that permits passage of air between the second portion of the first internal volume and the exterior of the head-mounted wearable device;
a third opening in the first single layer of material that permits passage of air between the second portion of the first internal volume and the exterior of the head-mounted wearable device;
a fourth opening extending through the first single layer of material, wherein the fourth opening permits passage of air between the first portion of the first internal volume and the exterior of the head-mounted wearable device;
a first layer of acoustic material positioned between the first opening and the exterior, wherein the first layer has a first thickness;
a second layer of acoustic material positioned between the second opening and the exterior, wherein the second layer has the first thickness;
a third layer of acoustic material positioned between the third opening and the exterior, wherein the third layer has the first thickness; and
a fourth layer of acoustic material positioned between the fourth opening and the exterior, wherein the fourth layer has the first thickness.
