Propagation and attenuation Sound in Air

[moussadjenane]

Hello all ;

  I have sources of sound (Db and Frequency) I want to see the propagation and attenuation in the air (graph 2 D) (Intensity Db = F (x, y));
I have sound and vibration toolkit i can note find solution.

Best regards

Hi,

It sounds like you want to model how sound travels through space. You have a source of sound with magnitude and frequency and you want to make a 'top down' 2D plot to show how sound travels from that source around your space. Is that correct?

First think about what assumptions you want to make. Is the propergation just in 2D or can it go up and down as well? What happens when sound reaches the edge of your space? Does it reflect? Do you have any objects in space that might cause absorption/reflection/refraction?

How do you want to model it? You could have a finite element approach, the sound and vibration toolkit might provide you some vi's to achieve this.

The problem is this: we have a stamping workshop contains large mechanical presses each press generates a noise,
we measure every noise of each press separately (Db, Hz)
  now I would like to do a simulation (total noise), noise intensity in each zone of the ateleir (Db = f (workshop area) = F (X, Y));
