Abstract: The invention generally pertains to enhancing a sensory perception of media. More particularly, the invention pertains to creating a composition having at least one frequency in the ultrasonic or infrasonic range. By way of example, the composition is inaudible in its preferred embodiment, but audible components are contemplated. One aspect of the invention relates to selecting a root frequency and then, via a mathematical operation or algorithm, calculating a single component frequency or a plurality of frequencies that lie in the infrasonic or ultrasonic range. Typically, infrasonic and ultrasonic frequencies lie outside the range of hearing for the average human being. The ultrasonic or infrasonic component frequency is not heard, yet its presence and its tonal characteristics may enhance a perception of the sensory content of a media conveyed through a media device.
