2. Have a look here: Weber
I have a couple of questions that i need help withh :
1. Suppose a radio is playing loudly at a sound level of 80 decibels. What decibel level would make the radio sound one-fourth as loud?
how are you suppose to start this question? you don't use the decibel scale do you?
2. Show that a sound with d decibels has intensity E0(10)^(d/10), where E0 is the intensity of a sound with 0 decibels.
I have no idea what that question is asking for. D:
thanks in advance (:
