F1 V10 "singing"
#4
Here's how the magic was achieved (technical/musical details via F1
Racing
> magazine):
>
> As we all know, a V10 engine produces five combustions per revolution
at a
> frequency per second of 60/(5 x revs per minute), which equals
12/rpm.
> Therefore, to work out the revs you need to hit a particular musical
note,
> you multiply the note's frequency by 12. To play a 440Hz 'A', for
example,
> you need 5,280rpm. For 'C', use 3,139rpm, for 'F' 4,191rpm, and so
on.
>
> Asiatech's French technicians (the engine, despite its name, is
derived
from
> a Peugeot design) simply programmed their engine to run through the
various
> rev/note ranges in the correct sequence. The result is delightful.
And

be

5,238rpm,
etc.

how do they do that !? seems like it would be similar to playing a trombone.. with your foot
Pretty cool idea nonetheless.
