Scientists and engineers are constantly looking at ways to either increase or decrease an echo. What recommendations would you make to increase or decrease the echo at your school, at home or a stadium? Why do you think the echo noise should be increased or decreased? How else could the science and technology of echos be used? (Answer: Sound reflection, or echos, occur best on hard and flat surfaces. Soft and uneven surfaces absorb the
