In human physiology and psychology, sound is the reception of sound waves and their perception by the brain. This is caused when the waves apply force to your eardrum, resulting in parts of your internal ear to move, leading your brain to process the movement as sound.
We, as humans, can only hear sound waves that have a frequency between 20 Hz and 20 kHz.
There are 6 separate ways in which sound waves are analyzed: Pitch, Loudness, Duration, Spatial Location, Sonic Texture, and Timbre. We will go into more detail on these in future posts, but for now, we want to start with the basics.
