2. Imagine that you are cutting grass with a gas powered law mower. Your ear is 2 meters from the source of the engine noise. Your friend is standing neariby so that his/her ear is 10 meters from the source of the noise. a. If you ear is exposed to a sound pressure of 2.0 x 10^6 KA (Mircopascals), what is the amplitude of the noise to which your friend is exposed? Consider the equations presented in class, keeping in mind that further a sound travels, the less energy it will have. b. What is the ratio of the sound pressure on your ears as compared to the sound pressure on your friend's ears? (Of in other words, how many time more sound pressure is on your ears, than his/hers.) 2.
