Diffraction The bending of a wave as it moves around an obstacle or passes through a narrow opening Refraction The bending of a wave as it passes at an angle from one medium to another Reverberation collection of reflected sounds in an enclosure, such as room. Early reverberation (good) the sound that reaches the listener after a small number of reflections. Enhances comprehension when listening with two ears. Late reverberation (bad) the sound reaching the listener after several reflections...
