HI people....


does anyone know any type of formula that relates pressure with amplitude?????

ehh im not too far into physics, but if I recall theres a few when you can combine. There are equations that deal with frequency and amplitude and there are also equations that deal with frequency and pressure so just put some equations together.

 

[physics junkie]

Pressure = Force/Area. For an ideal gas Pressure = nRT/V.

Amplitude is a feature of waves that tells you "how tall they are." Amplitude^2 is intensity. Intensity mostly comes up when you are dealing with the loudness of certain sounds...

Start here: http://hyperphysics.phy-astr.gsu.edu/hbase/sound/intens.html#c2

http://hyperphysics.phy-astr.gsu.edu/hbase/sound/soucon.html is the main link for looking at their sound resources. Hyperphysics is a great site for physics basics. My guess is you need a review of sound physics and not of the relation between pressure and amplitude.

Intensity is force per time unit area
I is proportional to Amplitude ^2

Using the Formulas: Pressure= Force/ Area, Intensity=1/2*density*A^2*V*angular freq, Acc=V/T, Angular freq= 2*pi/T

A^2= (Intensity*Time*Volume)/Area*pi*Pressure

Complicated!!!!
