1. The problem statement, all variables and given/known data When two sound sources of the same amplitude but of slightly different frequencies n1 and n2 are sounded simultaneously, the sound one hears has a frequency equal to Ans: (n1+n2)/2 2. Relevant equations 3. The attempt at a solution I have virtually no clue how that's the answer. I thought maybe the problem was related to beats, but it's clearly not. Beyond this, I just don't know at all.
