Answer 1

Answer:

It is a myth, they will announce today, that a duck's quack has no echo. But they will also add, a trifle sheepishly, that the echo of a duck's quack is very difficult to hear. Trevor Cox, of the acoustics research centre at the University of Salford, is an expert in techniques used to diffuse echoes.
