Hello
I just wanted to make sure I have these ideas right before I right them up in my physics coursework! I recently did some tests and got these relationships out, but didn't really have enough time to double-check them.
Ok. I took a simple test involving sound and distance. Is the distance proportional to the inverse square of sound intensity? So, as the distance increases a bit the intensity decreases by a lot?
Also, if I had a case around a speaker (say made from cardboard), but it still had the speaker exposed, would it increase the volume as opposed to no case? (I got this shown in my results - I think the case was called a "baffle" by my teacher)
I'm not too good around this area of physics as you may be able to tell!
Thanks!
