De amplitude is de hoogte van de trilling en zegt iets over hoe hard het geluid is (geluidssterkte). Dit wordt gemeten in decibel.
De trillingstijd is de tijd van één trilling, hoe groter de trillingstijd, hoe kleiner de frequentie.
Frequentie geeft informatie over de toonhoogte (hoe groter, hoe hoger) en wordt gemeten in Hertz.
The higher the frequency, the                    the pitch
The higher the frequency, the                    the wavelength
