Fact or Fiction on low frequency sound waves? In a 22' X 14' listening room playing a frequency at 20 Hz will you hear a true 20 Hz frequency. OK here is the scenario. This room is acoustically tight and there are no openings in the room for sound to escape. Given the fact that the tighter the sound-wave the higher the frequency. Does the wave compress in this room? If the wave does compress then would it be safe to say that the frequency is then modified and what you really hear is say beefed up 35 Hz or so? This has nothing to do with any ones sub-woofer, or specs, or independent reviews, etc.. I would like an opinion based solely on physics of sound.
