 Hi Tom,

 I would first try common earphones or headphones. It is unlikely that they=
 also have a dip at exactly 30.0 kHz. I think this is what Peter already wa=
nted to do.

 I see no big advantage in using a piezo transducer for this purpose. Their=
 frequency response is also far from perfect - there are usually numerous d=
ips and peaks as well...
