room harmonics

One thing I often like to do when I’m alone is to find one of the sound harmonics of the room I’m in. I achieve this by humming in a variety of frequencies until I find one that sounds louder than all the others (without actually humming any louder). For those that have not done A-level physics, this is basicly caused by the sound wave of your voice and the sound wave of the resulting echo interfering with each other. Most of the time, this interference doesn’t have any percievable effect, but if you pick just the right frequency, Bingo! the whole room resonates to the sound of your voice. Try it! Bathrooms are paticularly good because of the echo. So are empty lecture theatres.
