An investigation into the relationship between distance and sound

The aim of the experiment is to find the relationship between the distance and the sound, produced between an elastic band and a wall. The will be done by pulling back an elastic band at a different distance each time and shooting it at the wall and then recording the sound it produced using a speed level meter.

Pulling back an elastic band with an increasing distance each time and then shooting it at the wall will result in increasing speed in which the elastic band would go. This would mean that the kinetic energy would increase too because the theory of the kinetic energy states that the kinetic energy is proportional to the speed squared. But as the elastic band hits the wall all the kinetic energy gets lost either in the form of heat or sound. So, the more kinetic energy there is the more sound would occur. Thus, it can be predicted that as distance increases the kinetic energy increases.

Calculating Average sound

Avg.= (80 + 81 + 80) / 3 = 80.3 dB

Calculating errors for the average sound:

Eavg = (.05+0.05+0.05) /3 = 0.5

Presented data: Average sound recorded for each distance pulled back

Length of rubber band pulled back from 15 cm( + 0.1cm)

There were not any other errors caused by the apparatus. It was stable enough for the experiment. Therefore, there is no need to change the apparatus if this experiment would be done again. However, a protractor could be used to measure the angle so that there could be no problem with the angles in which the elastic band is shot at.

Another improvement would be to do this experiment in a quiet place such as a quiet room, so that there would not be any other sound captured by the sound level meter than the elastic band’s when hitting the wall.
