Sound Wave Energy loss question

[QUOTE="Paul Colby, post: 5486258, member: 584221"] Great, a quick Google gives the range of sound speed in aluminum as 3100 to 6400 m/s. I assume that this is dependent on the alloy selected. The sound speed in water is 1484 m/s. As a general rule of thumb is to match as closely as possible the speed of sound in the two medium. I would select an aluminum closer to 3100 m/s. I would also neglect the tube for now. At 40kH the wavelength is 8ish cm. This is much larger than the aluminum thickness. So I would go with the thinner of the two to minimize losses which I'm guessing are small in aluminum. [/QUOTE]
