Perhaps a bit off-topic, but has anyone had experience of using a hydrophone mounted on the underwater housing?

I've often wished I could record decent quality underwater audio along with video. Underwater sound scapes can be rich and it would up production value.

I came across a Housing Hydrophone w/ M14 Thread done by Ambient.de (link below) and would be interested to know if anyone has used it (or similar).
My main reservation: noise from camera operator (diver) would dominate more distant and actual environment sounds?

Thanks!

I don't have experience with housing mounting hydrophone but some with hydrophone hanging in the water. I am using an Aquarian hydrophone.

I suspect you can get easily interfering noises just by rubbing the housing, by the autofocus if it's in auto, even fan if your housing or camera has some. If the hydrophone is directional and let's say mounted forward; it could be better. When hanging the hydrophone in the water, I get noises of me rubbing the cable up to 1-2m from the hydrophone.

I shot only video and reviewing the footage my plain camera mic grabs all noise generated by me operating the camera. I clearly hear my clip banging on the housing, backfocus lever press, zoom or focus gear rotation and even shutter and other buttons.

Like @Davide DB I have to mute all the sound from my videos, since all I hear is mostly myself. It does make me more and more interested in rebreather diving, just to get rid of that part of the noise.

Thanks all, that would make sense.

Marelux make a hydrophone with a different housing mount to the Ambient one - it has an extension away from the housing. But judging from the short clip here, noises from the diver and camera operation are still going to dominate.

Ambient say: “With a frequency range of 70Hz-20kHz we designed a microphone able to capture the whole spectrum of sounds while effectively avoiding low frequency noise created by camera handling.” But I’m guessing you’re still going to have to be really careful with handling the housing during a take, as well as be on a rebreather / free diving.

Depending on what your are filming, you may consider - if that's possible for ypu - putting the housing on a tripod and step away by a few meters once you have framed your shot and started recording.
