Document Summary
Sound is the rhythmic changes in air pressure- things that vibrate generate these changes in pressure and our air transduces the sound energy- the change in air pressure is energy- it absorbs it. Converts this mechanical energy from air pressure fluctuations, into neural impulses. Things that vibrate change the air pressure around them. Depending on the amount and rate of change, we can hear these remote vibrations. We can basically hear all the richness around us by a function fo the varieties of sound pressure fluctuation rates- these frequencies. Waves. - how we look at them/interpret them, combine to make complex waves. How sound is ideally represented and how that representation helps us understand the way your ear and auditory system prosesses sound. An envelope of air pressure fluctuating in free space around us, it is emitting in multiple directions. In the actual case, it is fluctuating in multiple directions from one source.
