"for true impact in quantitave terms you're better off with an ultrasound Source Transducer and measuring intensity via NTR Systems Acoustic Intensity Measurement System...I can get you a discount...only $35k...Water conditioner not included.... "

Like other people on this forum, I live large and well ... an ultrasound Source Transducer sounds like just what I am looking for. I already have the water container ... remember that dang in-ground pool I love so well?

Are these piezoelectric transducers or round transducers? What will the defraction effects in the Frenzel zone be? Any idea? &;-)

Transducers are typically constructed with Piezoceramic elements in either phased array or single high energy pulsed configuration...Of course with the increased use of Space age PVDF Materials, its possible to reverse the flow of current in a membrane hydrophone but precision is poor. And we've yet to discuss using high intensity lasers to produce supersonic shock waves from phase change and cavitation artifacts...you'll definitely want to use a rugged Piezoceramic... possibly a reflected as opposed to direct measure as well depending on your budget...I'm afraid your pool will have too much surface area and dissolved gasses will cause cavitation at higher Intensities...Of course if you're studying Sonoluminesence...all the better. A water conditioner would be a sound(pardon the pun) investment since I understand you have a considerable follicular deposition problem of the canine variety...
