I'm very excited over the successful test Tuesday of a locomotive whistle designed by Cary Atkinson, using interactive spreadsheets based on the formulas from my research in Flue Pipe Acoustics! Successful whistle design never need be the result of trial and error again! There was no tweaking involved here. Turn up the volume and give it a listen!! I love the echoes!!

One could also use these spreadsheets to design a whistle for a riverboat.
