Standing Waves

What are they? Why should we avoid them when designing a home cinema room? And, how do we avoid them?

Sound travels in waves. The length of the wave depends on the frequency of the sound (actually it’s the other way round but let’s not split hairs!), and when that wave hits a hard flat surface it is reflected. Speakers set up “in a field somewhere in Hampshire” offer direct sound from the speakers to ears. There are no reflections from walls, ceiling etc so no sound comes back to you a second time from a rear wall. The sound waves are clean and undisturbed. Place the speakers in a room and chaos is created.
