Hello,
This might be slightly off the course of normal conversation for this group=
,
but I need to harness the collective brainpower for some help with a
hydrophone conundrum.
First let me explain how I plan to use it. In October, I=B9ll be
participating in a group swim from Alcatraz to San Francisco. While
training for the swim, I couldn=B9t help but wonder what 250 swimmers
high-tailing it through the 62 degree water of San Francisco Bay would soun=
d
like, from just below the surface. Getting a hydrophone and attaching it t=
o
my wetsuit is the easy part, but I=B9m having trouble figuring out how to
record. I=B9d like to use my consumer minidisc recorder, which can easily =
be
kept dry in a pelican case, but the problem is how to get the cable from th=
e
hydrophone to the recorder. So my questions are:
1. Is there such a thing as a wireless hydrophone that would work with a
consumer MD recorder mounted nearby?
2. If not, any ideas as to how I might connect the hydrophone=B9s cable to
the MD recorder while keeping the recorder dry? (bearing in mind that both
items would probably be strapped or taped around my torso, and thus exposed
to the water for the whole hour or so I=B9ll be swimming)
3. Since I=B9ve never used a hydrophone before, is this even a worthwhile
thing to try? Or would the drag created by my swimming just make a lot of
noise and not capture anything else? I think I can rig it in such a way
that it won=B9t tangle in my feet and so forth, but I=B9m not sure how effe=
ctive
the hydrophone is if it=B9s constantly moving.
4. Any recommendations on a fairly cheap hydrophone?
Any other suggestions would be greatly appreciated. The recording might en=
d
up being just a bunch of swimmers breathing and arms slapping the surface,
but I thought it might be worth a shot anyway...
Thanks very much in advance,
Tony Cross
