Even with the ringer set on maximum volume, I tend not to hear my phone ringing when I'm out walking on a busy London street. I'd like a ringtone that will be audible over traffic noise, but not be earsplitting or annoying when I'm indoors. Are there any acoustic properties (other than sheer loudness) that I should look for in a ringtone to help it stand out against a background of car engines and other street noise?
Someone once told me that a lot of the distinctive "sound" of opera developed as a way to be heard without amplification. Two specific claims I remember: diphthongs are separated into multiple monophthonic syllables, and phonemes which are hard to sing loudly are replaced by easier ones (which sometimes don't even exist in that language). There were others relating to actual singing that I forgot. Does anyone know of a good discussion of this topic that talks about biomechanics and acoustics? Not to ignore artistic and historical considerations, but I'm looking for a somewhat technical discussion. In particular, I'd love to see a comparison with singing styles developed for amplification and recording.

If you take off a pair of headphones and lay them down somewhere, the music sounds like it's in a different pitch than when they're on your head. Why?

What, besides the volume, distinguishes the sound ("timbre") of a string quartet and chamber orchestra? Put another way, if I took a recording of myself singing, and overlaid 100 copies of the track on top of each other, would I sound like a choir section?

Heard an NPR story 7(ish) years ago about a guy who measures the pitch of various sources of barely-audible workspace/home background noise (eg. harddrive spinning, refrigerator compressor running, and the flyback transformer on your television) and seeing what chords they made. He contested that different chords would affect peoples' productivity, attitudes, etc. I have some questions about this. [more inside]

Electric/electronic accordions. What do they sound like? How's the volume control? Is there any recorded music they've been used it? Are they good for moderately experienced keyboardists who've never played accordion but think they're really cool (especially the auto-transpose stuff)? [more inside]
