'[OT]: Properties of Ceramic Ultrasonic Transducer'

Hello,

I am thinking of purchasing some ceramic ultrasonic transducers for use in a range measuring system.  Can anyone tell me or point me to a source explaining the advantages and disadvantages of using a given frequency (i.e. is 40kHz better or worse than a 500kHz transducer when trying to determine distance).  Also, what are the advantages/disadvantages between a ceramic and electostatic transducer?  The Polariod website indicates a electrostatic transducer is more sensitive, but does not elaborate.  How much more sensitive? will this matter for detecting objects between 3cm and 5m?

Regards,
Donovan
