Hello All

I am in the market for some acouistic modelling software. I would need
this to do barrier attenuatiin calculations for barriers along the
edge of roads etc. Also for noise affecting housing developments etc.
I know of two systems. These are SoundPlan and Cadna. Does anybody
know of any other systems as these seem to be a little all singing all
dancing for my requirements. Does anyone know of a lite version where
extra modules can be bolted on?

Look forward to hearing your views.

Cheers

Scott
