calculate resonant frequency

Hello all...

I'm trying to find information on how to calculate the resonant frequency of a "sandwich" of materials like plywood and sheet rock for a panel to be used for a drum riser.

Is there an equation for this that anybody would like to share?

I don't yet know what the final sandwich will be - I have some left over construction material that I would like to use.

Thanks in advance,
Rick

Thanks,

I looked over it quickly yesterday. Hopefully one of those equations fits my application...

Best regards,
Rick
