Does the material or shape of the sonic tank impact their effectiveness?
Tank materials play a large part in the absorption and dispersion of ultrasonics. As mentioned previously soft materials such as plastics will absorb the ultrasonics. They can however be used if the ultrasonic power is boosted to overcome the absorption. Tanks shape plays less of a part in design but needs to be considered. Ultrasonic power does reflect from not only tank walls but also from the water surface.
