There seems to be a trend (at least here on the HB and, therefore, no doubt in the real world) for bizarrely loud musical instruments. Turbojet-powered woodwind, metal- shredding pipe organs and the like.
But much music was written for vocal accompaniment, and these ideas leave the human voice trailing quietly behind. True, one can use a microphone and amplification, but where's the fun in that?
Proposed, therefore, is a turbo-augmented vocalist. Relatively modest surgery can provide a port connected to the lower part of the trachea, and opening onto the front of the chest. This port, in turn, can be connected to a chest-mounted power- driven fan. (A small jet engine would be ideal, but only if thermal issues can be managed; for the time being, an electrically-driven fan will have to do.)
Thus enhanced, the vocalist will be able to belt out a tune with a phenomenal volume. Moreover, said vocalist should be able to sustain a fantastically long note - they will simply breath in and out normally, causing only a very minor fluctuation in the airflow over the vocal cords.-- MaxwellBuchanan, Nov 06 2019 Beat frequency https://en.wikipedi...ki/Beat_(acoustics)Two different frequencies, dancing together [neutrinos_shadow, Nov 07 2019] <Contemplates connecting up Justin Bieber to a 5 Bar air line/>
Bunbunbunbunbunbunbun ..... [+]-- 8th of 7, Nov 06 2019 Option: use a positive-displacement compressor (piston type) instead of a fan. Then you can get fluctuating airflow at a controllable frequency as well.-- neutrinos_shadow, Nov 06 2019 Only if the piston operates at a few hundred hertz, though.-- MaxwellBuchanan, Nov 06 2019 No no, controllable frequency. To work WITH the vocal chords, not instead of. So you can get interference effects (beat frequency) and stuff. Maybe a fan AND a piston (like "AC over DC" electrical signal) in parallel.-- neutrinos_shadow, Nov 06 2019 Our porpoises might be crossed here. The vocal cords (specifically the tension in them) determine the frequency, but maybe that's what you meant.-- MaxwellBuchanan, Nov 06 2019 [MaxwellBuchanan], see linky. The vocal chords provide one freq., the piston the other. As the air flows and stops/reverses, sound happens, or not (in particular, air flowing backwards through the vocal chords (and mouth etc) sounds really weird).-- neutrinos_shadow, Nov 07 2019 <Clippy> Sounds like you're designing a a mouth organ... </Clippy>-- Dub, Nov 07 2019 Initial estimates are suggesting that to inflate Justin Bieber's body to the same size as his ego will require more than 80% of your planet's atmospheric gases.
That's OK with you, is it ?
We may have to boil a proportion of the oceans as well if the gas alone proves insufficient; usefully, water has an excellent coefficient of expansion.-- 8th of 7, Nov 07 2019 Can we use him as a CO2 sink?-- MaxwellBuchanan, Nov 07 2019 random, halfbakery
