Abstract
An ultrasonic audio system includes adaptive equalization techniques configured to adjust the overall output of the ultrasonic audio system. This can be done by adjusting the equalization of the electronic audio signal representing the audio content being reproduced by the ultrasonic audio system. For example, in various embodiments, systems and methods can be implemented to increase the gain of higher frequency portions of the electronic audio signal while making a corresponding decrease in the amount of gain at the lower frequency portions of the same signal.
