1. An ultrasound transducer comprising:
a plurality of capacitive ultrasound transducer elements; and
a base having a largest dimension sized and shaped to be disposed with an external ear canal, wherein the plurality of capacitive ultrasound transducer elements is mounted on the base;
wherein the plurality of capacitive ultrasound transducer elements is configured to form an ultrasound waveform having an angular beam spread through a gaseous medium of greater than 15 degrees and an attenuation loss through the gaseous medium of greater than 10 dB measured at a distance from 12.5 mm to 25 mm along a primary transmission axis.
