Understanding Source Differentiation in Sound Wave Superposition

AI Thread Summary
Sound waves can be distinguished by their unique wave shapes, even when playing the same note, due to differences in timbre. When multiple sound sources, like a flute and a guitar, superimpose, their distinct waveforms combine, creating a complex sound that retains identifiable characteristics of each instrument. This differentiation allows listeners to recognize and separate the sounds despite their simultaneous occurrence. The amplitude of the combined sound is the sum of the individual amplitudes, but the unique wave shapes play a crucial role in perception. Understanding these principles clarifies how audiences can discern between different musical instruments.

Homework Statement



If sound waves superimpose, why is a person in the audience able to distinguish different sources of sound eg flute and guitar.

Homework Equations



Amplitude (A+B) = Amplitude (A) + Amplitude (B)


The Attempt at a Solution

What's the difference between the sound of a flute and guitar?
 
The wave shape would be different, and they could be playing different notes at different times (assuming they are both playing together in a band for example).
How does this help?

That's right. So if the wave shapes are different (even for the same note), what would happen when the two waves are added? Intuitively, if the two wave shapes are different (even for the same note), can you distinguish the sounds coming from flute and a guitar?
 
Sorry that doesn't make any sense to me ?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
