i've found kits for self-build hydrophones but so far i've tried using 
a simple boundary mic and rolling of all high frequencies whilst adding 
gain around 20hz
but there is alot of inherent noise within my dirty mac's mini jack 
input (i'm now looking at the m-audio firewire 410)

through the headphones, amongst all the sub bass, i could hear cars 
driving up my road before hearing them with my naked ears

i was also thinking if the effect air-pressure had on another object 
(maybe a balloon?) could be recorded
