acoustic mine Meaning and Definition
acoustic mine
جَہاز کے اِنجَنوں دھُرے اور دھَکیلچوں وَغیرَہ سے زیرِ آب پھَٹ جانے والی سُرُنگ
An acoustic mine is a type of naval mine which monitors audio activity in its vicinity. Depending on its design, it will either actively send out audio pulses, not unlike a sonar, listening to the speed at which the echo returns to it or passively listen to its environment, depending only on the noise that is made without its interference.
