    It depends on how loud the sound is and where the whale is positioned.
    There are layers in the sea which reflect sound amazingly well and
    would allow a humpback to hear a sound travelling across an entire
    ocean basin, up to 5,000 miles. However, in their normal activities on
    the mating grounds, when the males sing, we believe that they may be
    heard by other humpbacks for several miles away (probably less than 10
    miles).
