| A man on shore would detonate a mine when he heard, thru the hydrophone, what he thought was a passing ship. |
| These units have been constructed in-house using commercial hydrophone and geophone elements. |
| The standoff distance between the hydrophone and polystyrene plate was 0.5 mm for the excimer and ruby lasers. |
| It was agreed that this would also be appropriate for hydrophone phase comparisons. |
| The hydrophone array detected an unusual shape, which, following data processing and analysis, was determined to be a shipwreck. |
| This combination is analogous to that of a hydrophone and endows these fishes with a remarkable sensitivity to sound. |
