I made it clear that this was not a sound recording of the Hum. It has been known for many years that not everybody hears the same sound and there is no reason why they should. The perception of noise is generated inside the body and will depend upon the individual. Some perceive it as a low rumble others at a much higher frequency. Some hear it as a continuous note and some as a pulse which they describe as Morse Code . The purpose of this exercise is measurement, for without measurement you have nothing, what it sounds like is irrelevant.
