In fact, it is our ability to create and comprehend sounds in the form of speech that is integral to our human development. As physicians we assess heart sounds, breath sounds, and bowel sounds, but few will contemplate the nature of sound. Without understanding the physical properties of sound and their interactions with the surrounding medium, it is difficult to understand the images produced in clinical ultrasound. The critical care practitioner also often acts as a sonographer, whose responsibility is to operate the equipment, obtain images, distinguish between real structures and artifacts, and manipulate the transducer. Without a solid knowledge of basic sound principles, these tasks are virtually impossible.
