AI Thread Summary
The discussion revolves around the confusion regarding the combination of sound wave intensities within one critical bandwidth. The user seeks clarity on whether to sum or average the intensities of two sounds that fall within this bandwidth. There is a misconception that summing the intensities leads to an excessively high value, conflicting with the understanding that combined intensity should be lower. Ultimately, the user resolves the confusion by realizing that the correct approach is to sum the intensities, correcting a previous misunderstanding related to logarithmic calculations. This highlights the importance of accurately applying mathematical principles when evaluating sound intensity.

Hello!

I'm getting a bit confused with how to deal with sound waves that are within one critical bandwidth of each other.

I do not fully understand how you are meant to combine the intensities of sound waves when they lie within one critical bandwidth?! I would really appreciate some clarity as I am getting very muddled!

I understand that separately (out with a critical band) the sum of the individual intensities would be more than that of the combined (within one critical bandwidth) intensities. This is where my confusion arises, I don't understand how exactly you can combine these intensities to get the overall result (from which I could evaluate the intensity level) ...the material online seems to conflict...

Basically, if I have two sounds, in one critical bandwidth, I can separately deduce their intensities, but then to evaluate the total intensity, am I meant to sum them, or take an average? By summing them I get an enormous value, which doesn't seem to correlate with the idea that the overall intensity should be smaller. But this is the approach that I have been finding online.


Any ideas/help?!?


Thank you in advance

Hannah :-D :-D :-D

Solved it! It must be a sum, was mistaking my logs for lns :-(
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
