Re: Dino Noises*

One important point frequently overlooked in the noise production of 
dinosaurs is the affects of soft tissue on sound. Tissue has its own 
resonating frequency and dampening effects that must be taken into 
account. Thus the PVC Parasaurolophus noise probably did not sound 
anything like the actual noise. Lining the PVC with a tissue-like 
material and increasing the volume of air to approximate the volume of 
the Parasaurolophus lungs - not Weishampels' puny lungs (by dinosaur 
standards) would be a start.
