Their approach is based on a mathematical analysis of the sound waves produced by the beating heart known as Empirical Mode Decomposition (EMD). ... Micro honeycomb materials enable new physics in aicraft sound reduction
... a honeycomb-like structure that traps sound regardless of frequency. Instead of resonating, sound waves plunge into the channels and dissipate through a process called viscous shear.
Viscous shear ... Making waves

... , it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important...St. Jude finds 'dancing' hair cells are key to humans' acute hearing
... would be far less sensitive, since sound waves entering the cochlea are severely diminished ... electrically stimulate an outer hair cell with a sound, the cell body spontaneously elongates and contracts ... UT Southwestern researcher: Supplemental breast ultrasound boosts cancer detection
... half had a personal history of breast cancer.
Breast ultrasound is a noninvasive procedure that uses sound waves to make a picture of the tissues inside the breast. It has traditionally been used ... Adding ultrasound screening to mammography brings benefits, risks
