4. The Kinds Of Stuff We Hear
All about our amazing auditory system.
A List Of The Kinds Of Stuff We Hear
Let’s make a list.
We detect stuff happening around us, from all directions, all the time.
We quickly and easily identify the nature of the stuff happening, to a point where we can casually tell the difference between such small differences as the pressure-variations generated respectively by the footsteps of Igor and Samantha, as they walk around in the same room we are in.
We quickly (and mostly subconsciously) detect the presence of environmental features of our space, like walls, ceilings, etc., even though they don’t generate gas pressure variations. We do this by detecting the REFLECTIONS of the pressure variations generated by the footfalls of Igor and/or Samantha. Amazing!
And when either Igor or Samantha (not their real names, by the way) generates pressure-variations using the cute-looking orifice located at the center of their respective heads, we have learned to quickly come to understand that it is time to (a) put out the garbage, (b) get the car fixed, or perhaps on a good day (c) join Igor or Samantha in ingesting a liquid derived from fermented fruits and/or grains. We call this “communication through the use of spoken language.” It is a totally amazing trick!
And finally, in a truly remarkable and almost totally incomprehensible way for our alien visitor and new friend Zork-11, those of us called recording engineers spend our lives fooling around with all these tiny gas pressure-variations for fun, and on a few rare occasions, for precious metals as well! Like totally awesomely amazing! Really!!
