contact mic

["faza.rm" faza.rm]

Hello..
I am new here...
I am doin this installation for a gallery. There will be a subwoofer inthe =
middle of the gallery
and a pile of sand around it.. the viewers are required to walk on the sand=
..
I am trying to buy contact mics and burry them in the sand so that the soun=
ds of their
footstep will be picked up and transmitted to the speaker...
However the contact mics that  i got does not seem to be as senstive as i t=
hought it would
be.. i am just fixing them onto the floor..
I was wonderin if anyone know of a good material to stick these contact mic=
s to get the audio
of the crushin noise of the sand..
hope this messege is not all too confusin..

thanks
