Acoustic Simulation - Pachyderm

Hi, @Arthur
Am having issues with calculation the STI (Speech Transmission Index) using pachyderm. I tried plugging in the noise level with the panel, But still it wouldn’t work. Any advise from your end would be greatly appreciated. Thanks

Hi,

The noise level is 8 numbers, one value for each octave band.
Try with a noise criterion spectrum.

Arthur

Can the values of SPL be considered as Noise levels for this auditorium model?

Follow-up Question?

Any recommendations for standards which I can refer to, for setting up materials for Absorption, scattering and transparency coefficients?

Thanks for your prompt reply.
