Question

The loudest sound produced by a living organism on Earth is made by the bowhead whale (Balaena mysticetus). These whales can produce a sound that, if heard in air at a distance of 3.50 m , would have an intensity level of 157 dB . This is roughly the equivalent of 5000 trumpeting elephants.

Question: How far away can you be from a 157 dB sound and still just barely hear it?(Assume a point source, and ignore reflections and absorption.)
