But if it just so happens that there are no creatures nearby to catch those waves with their auditory senses, and the energy merely propagates into nothing, does it make a sound at all? Our eyes see what’s happening because they receive the electromagnetic waves of the light reflected from the guitar string, so that we can recognize the beautiful sinusoidal waves on the string. A sound wave is an air pressure disturbance that results from vibration. For the next 16 years (1995-2011) I was a physics professor at Kettering . The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. It creates Unity instead of separation. In Scientific American Volume 50 Number 14 (April 1884) the question was asked “If a tree were to fall on an uninhabited island, would there be any sound?” And gave a more technical answer, “Sound is vibration, transmitted to our senses through the mechanism of the ear, and recognized as sound only at our nerve centers. Massachusetts Institute of Technology: MIT OpenCourseWare, https://ocw.mit.edu. From one perspective the only thing that makes sound exist are ears, human or otherwise, and nervous systems and brains (or ganglia) to interpret and decode those vibrations into meaningful data – i.e., sound. This is an example of resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion. Like waves of vibration that are eternally connected and influenced by one another, our understanding and appreciation of vibro-tactile healing has ebbed and flowed. One hertz equals one cycle (vibration, or sound wave) per second. Vibrations are known as: Vibration waves and sound DRAFT. When the waves reach your ear, your eardrum vibrates and your brain interprets that vibration as sound.
