Has anyone looked into improving sound transmission/sensitivity with the underwater housing?
Lamont et al 2022 showed lower sensitivity in the HydroMoth compared to a Soundtrap, presumably at least in part due to the effect of the water/housing/air media interface.
I'm thinknig of applying a fluid or gel between the microphone and housing to improve transmission, e.g. silicone or silicone grease, or even trying to fill the housing with hydrophone oil. Obviously I wouldn't want to damage any components though. Would this be likely to cause any problems?
