In a sound wave, how do frequency and amplitude relate to perceptual qualities?

Explanation:
The main idea is how the basic properties of a sound wave map to what we hear. When the wave has more cycles per second, its frequency is higher, and we perceive that as a higher pitch. When the wave’s oscillations are larger in size, its amplitude is greater, and we perceive that as a louder sound. Wavelength and speed relate to physical propagation, not directly to how we hear a sound's quality, and brightness is a term used for light, not sound. So the frequency–pitch and amplitude–loudness relationship is the key mapping.
