The distance from one compression to the next in a sound wave wavelength (longitud de onda)
Loudness of a sound, height of a sound wave amplitude (amplitud)
A measure of how high or low a sound is, the steepness of a sound wave pitch (echada)
The speed at which a sound wave travels through air in miles per hour about 768 miles per hour, much slower than light
A sound reflection echo (eco)

Why is there no sound in outer space? There is no matter for sound waves to vibrate
