I realise this is probably not the kind of request you get everyday and
would like to say thanks in advance for any advise you folks might be
able to offer.
Im a multimedia artist working here in ireland. I have an installation
which will be part of a music festival here in september.
For the installation i have proposed to capture the sound of 10000 or
so people all jumnping in unison to the music and play it out through
small speakers situated at the far end of the festival from the main
stages. i also anticipate picking up some of the music as it is
transmitted into the ground via the mainstage (if he had ears) would
hear under the festival.
I was thinking a geophone would be the right device to capture the
sound with. Im most interested in the 20 to 1200Hz range of
I have no experience with this type of equipment and was hoping you
might be able to advise me on a suitable device for this project? Also
what type of amplification would i need to bring the output signal up
to a line level, (around 100mV).
Any advise such as whether a geophone would be sensitive across this
frequency range, where i might get one, how much they cost etc that
could be offered would be really great.
