Teaching ultrasound in air

The use of ultrasonics sensors in laboratory exercises and robotics has become popular in recent years. That is, however, only one avenue for exploring the world of inaudible sound that is around us. This talk discusses exercises to interact with the ultrasonic world surrounding us using smartphones, computers, and tablets. Messages can be sent through analog or digital means and the very concept of what is inaudible varies significantly from one person to another. The use of ultrasound is not limited to range finding but also spans communication and art.
