Wireless, wearable sensors are all the rage with millions of people now sporting fitness trackers on their wrists. These devices can count footsteps, monitor heart rate and other vital signs. Now researchers report in the journal ACS Sensors that they have developed a 3-D printed sensor worn on the ear that measures one of the most basic medical indicators of health in real time: core body temperature.
Many attempts to explain how past people experienced their wider world have focused on sight at the expense of sound, but researchers from the University at Albany and the University at Buffalo have developed a tool that puts sound back into the ancient landscape.
Devoted runners suffer from a surprisingly high rate of injury. One reason for these injuries is that runners endure many shocks from the impact, and these cause vibrations that travel from the foot throughout the entire body. Delphine Chadefaux, a researcher who focuses on acoustics and biomechanics, studies these repetitive shocks and investigates how runners adapt their running patterns, and will share some of the insights from her research during Acoustics '17 Boston.
One popular theory about the Paleolithic cave paintings proposes that sites were chosen based on the acoustics in the caves. The originators of the theory reported a causal connection between the 'points of resonance' in three French caves and the position of Paleolithic cave paintings. David Lubman, an acoustic scientist and fellow of ASA, will share some of the insights from his research during Acoustics '17 Boston, held June 25-29, in Boston, Mass.
The technique enables the detection of gases, such as atmospheric pollutants, present in extremely small quantities that are otherwise difficult or impossible to detect.
Findings could transform treatment worldwide and enhance patient care.
A new strategy for sending acoustic waves through water could potentially open up the world of high-speed communications to divers, marine research vessels, remote ocean monitors, deep sea robots, and submarines. By taking advantage of the dynamic rotation generated as the acoustic wave travels, also known as its orbital angular momentum, Berkeley Lab researchers were able to pack more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.
In 22 years, Karin Heineman has been behind the camera for hundreds of scientific stories. By bringing a plethora of scientists into the world of media, she has garnered unique expertise in bridging the communication gap between those in and out of the lab. During Acoustics '17 Boston, Heineman, executive producer of Inside Science TV, will share some of her experience and highlight important elements of capturing the stories of science with video.
Ultrasound is commonly used in diagnostic imaging of the body's soft tissues, including muscles, joints, tendons and internal organs. A technology called high-intensity focused ultrasound is also being explored for therapeutic uses including the removal of uterine fibroids and the destruction of tumors. A suite of noninvasive, adaptive focusing techniques -- that allow ultrasonic beams to be focused through the rib cage and skull -- will be described during Acoustics '17 Boston.
The way you hear and interpret the sounds around you changes as you move. That's how sound in the real world works. Now imagine if it worked that way while you were listening to a recording of a concert or playing a video game in virtual reality. During Acoustics '17 Boston, Ivan J. Tashev and Hannes Gamper, with Microsoft's Audio and Acoustics Research Group, will explain how they are using head related transfer functions (HRTF) to create an immersive sound environment.
