Love to hear your recordings when you get them. I'm presently working on a =
project that involves collecting primate information, video and audio. Yes =
silica gel. It can be purchased in thin flat aluminum boxes with a color se=
nsor that changes color as it picks up humidity. They're more expensive tha=
n bulk but you can tell how far gone they are and the aluminum shell allow =
them to be toasted over a fire in a frying pan to restore them. I purchase =
them from the local hardware store which is also a locksmith. I think they'=
re sold to be put in safes to keep the contents dry. I use a Pelican case f=
or my laptop but they're pricey.
Are the speakers so that you can hear the recordings or so that you can pla=
y them back to the howlers? If it's to listen, then headphones are the best=
field solution. You should really be using headphones (the in-ear kind are=
less annoying in the field) for your recording anyway. If it's for playbac=
k, the main problem is the amplification. Will you have a source of power? =
Decent powerful amplified speakers that are battery operated are available =
but they're not great to hump into the field.
