Abstract:
1. A method for providing audio content to the hearing impaired, the method comprising: evaluating a hearing response profile of a listener to an audio modulated ultrasonic carrier signal; receiving audio content from an audio source; adjusting the audio content to generate equalized audio content based on the hearing response profile, the equalization being chosen to at least partially compensate for the listener's hearing based on the response profile; modulating the equalized audio content onto an ultrasonic carrier signal to generate an equalized audio modulated ultrasonic carrier signal, and converting the equalized audio modulated ultrasonic carrier signal into an ultrasonic pressure wave representing the equalized audio modulated ultrasonic carrier signal; and wherein the ultrasonic pressure wave is demodulated in air, causing audio content representing the equalized audio content to be created, enabling the listener to hear and recognize the audio content.
