Thanks for the help guys. Ok this make sense. But frequency isn't the only variable of a sound wave, how can we determine the amplitude at a specific time? Thanks for this, will take a look at the video

Apologies for the large gaps between my replies. The problem is I haven't figured out that frequency will be conserved, I just guessed it. I have no reason why that's the case! I want to understand the mechanism by which the waves on the string cause the waves in the air.

I obviously competely misunderstood the format of these forums. I can't deal with this style of answering where I'm being addressed like a stupid schoolboy, even if that is how I appear to you! I'm not able to figure this out. Obviously the wave speed is different, and wave speed depends on wave...

Well I don't know, that's what I'm asking.

Thanks for the recommendation - I'll look into it! I don't know, that's my question! As the wave on the string (and consequently the body) changes, the sound you hear changes. For example, what determines the amplitude of the pressure variations? I'm guessing it's related to the amplitude of...

Thanks for the reply. I understand this, but I was looking for something more explicit. If I'm explicitly given a mathematical expression describing the vibration of a guitar string (or body), I want the mathematical expression describing the generated sound wave. Ah ok, this simplfies things a...

I'm trying to understand how a vibrating body produces oscillations in sound pressure. I've been through derivations and solutions of the wave equation for a string, but I don't understand the transition from waves on a string to sound pressure waves. How are the waves on a string or drum...
