An introduction to acoustic thermometry
An air filled olive jar teaches signal conditioning
Jim Williams and Omar Sanchez-Felipe
We occasionally lecture to university engineering students. A goal of these lectures is to present technology in a novel, even charming, way. This hopefully entices the student towards the topic; an aroused curiosity is fertile ground for education. One such lecture investigates acoustic thermometry as an example of signal conditioning techniques. This subject has drawn enough interest that it is presented here for wider dissemination and as supplementary material for future acoustic thermometry lectures.
Acoustic thermometry is an arcane, elegant temperature measurement technique. ...
