I feel like a little philosophy tonight. When that tree falls in the
forest, it generates a wave front in the air. That wave can be measured by
a pressure sensitive device. That wave exists whether anyone is there or
not. However, that is not sound. Sound occurs in the brain when our
special pressure sensitive device called the ear translates that pressure
energy into something the brain can process and assign meaning to.

One might even compare it to radio. The radio waves, generated either
naturally or artificially, exist whether or not we have a device to sense
them. Just because you turn off your radio doesn't mean the local radio
station stops transmitting it merely means that you have no way of sensing
whether or not they are indeed still transmitting.
