The mechanical process by which sound waves are received & perceived is a fascinating real-time look into how we are fundamentally and ceaselessly connected with our threedimensional environment via the realm of the five senses, and how we interface this information to produce, enhance, or alter different states of consciousness. This process begins as sound waves move through the air and interact with the canal of the outer ear. The canal channels the sound waves, and due to its length of roughly two centimeters, it is capable of amplifying sounds approximating the frequency of 3000Hz. As sound travels through this canal, it is in the form of a wave with alternating patterns of high and low pressure regions, and then as it meets the eardrum, it is converted into the vibrations of the inner bone structure.
