Morphology

hydroacoustic = acoustic (transparent) = hydro + acoust + ic

The word is a straightforward technical combination of hydro- 'water' and acoustic 'relating to sound'.

Etymology

The word hydroacoustic is made of hydro- 'water' and acoustic 'sound', as in an acoustic guitar. So it means 'sound in water', which is why it is used for the study or use of sound underwater.
