Pitch Human perception of the frequency of sound.
Refraction Change direction of a wave when it changes speed as it travels from one material into another.
Reverberation Repeated echoes of sound waves.
Transverse Waves Mechanical wave that causes particles in matter to move at right angles to the direction the wave travels.
