You are trying to overhear a juicy conversation, but from your distance of 15.0 , it sounds like only an average whisper of 35.0 . So you decide to move closer to give the conversation a sound level of 60.0 instead. How close should you come? (in cm)

Answers

The sound level of the conversation you are trying to overhear is determined by the ratio between the sound level at the source (the speakers) and your distance from the source. The sound level of the conversation you are trying to overhear is 60.0 and the initial distance you were at was 15.0 . So, we can calculate the ratio of your distance from the speaker to be 60/15 = 4. This means that in order to get a sound level of 60.0 , you need to move 4 times closer to the speaker; this would mean you should move to a distance of 15/4 = 3.75 cm from the speakers to get a sound level of 60.0 .
