I've been thinking about guitar noises again and have a question for the amp experts. If I were wearing sound proof headphones, blindfolded myself (for dramatic effect), and stood in front of an amp stack, would I be able to feel the sound as it came from the amp? Obviously if the amp volume were loud enough, I'd feel vibrations from the floor and everywhere else. (I'm not sure I'd feel it if I were floating off the ground ) Anyone who has lived above a bar with live music knows you can feel the vibrations. Here's my question. Would you still feel the sound if it were coming from the amp at high pitch (as in falsetto high pitch). In other words, do high pitch sounds have more or less, uh . . . hmm, sound force (for lack of a word to describe the feeling of sound)? Another way to put it, do you need more volume to physically feel high pitched tones?
