Yes but what I don't know is the location of the tap. Note that the tap does not occur at a fixed location but varies in time. I need the amplitudes to probe the position of the tap. Otherwise how else?
Hi all,
I was wondering whether someone can help/guide me. I am doing a project that involves sound propagation in solids. Basically, I have two microphones placed on a surface (say a piece of wood). Then, when a person taps on the surface I can detect the tap and determine the amplitude of tap...

Thanks for the reply. Yeah I probably could use an ultrasonic emitter and it could probably work. But I don't want to go that way. That's been done. And you already get commercial devices that use that principle. What I want is the intelligence of the device to be in the software rather than the...
Hi,
I wasn't really sure whether to put this post under Physics or Engineering. I was just wondering whether someone can gimme some help or info or guidance... I am currently working on a project in which I am using the FFT (Fast Fourier transform) algorithm.
In a nutshell, I am trying to use...
