How is sound used in medicine?

Sound waves can assess potentially dangerous atherosclerotic plaques, monitor chronic liver disease, and help deliver drugs to particular locations within the body. Ultrasound devices can image tumors deep inside the body, and acoustical energy can be focused upon those tumors as a way of treating cancer.

Is sound analog or digital?

Sound itself is a continuous wave; it is an analog signal. This means that one cannot detect the precise moment the pitch changes.
