How Nigerian Music Can Help You Choose a Ripe Watermelon

Acoustical Society of America (ASA)

The quickest way to decide if a watermelon is ripe or not is by tapping on it. And if you’re having trouble detecting the subtleties of the sound, listen to some Nigerian traditional music to get your ears attuned. Nigerian researcher Stephen Onwubiko has found a link between the sounds of drumming in traditional Nigerian music and the sound of fingers drumming on watermelons in the markets. His team will present the findings at the 177th ASA Meeting, May 13-17.

Want to Expand Your Toddler’s Vocabulary? Find Another Child

Acoustical Society of America (ASA)

Children glean all kinds of information from the people around them. In particular, children mimic and learn speech patterns from their family. Previous work has shown that infants attend selectively to their mother’s voice over another female’s voice. But new research suggests that children learn new words best from other children. Yuanyuan Wang will present research findings from a collaborative work with Amanda Seidl from Purdue University at the 177th ASA Meeting, May 13-17.

Signals to Noise in Acoustic Vehicles Alerting Systems

Acoustical Society of America (ASA)

If you’ve ever wished for a quieter commute, you may be in luck: The low-emission electric vehicles of tomorrow are expected to lower noise pollution as well as air pollution. The prospect of a future powered by environmentally friendly electric vehicles is leading experts to consider the benefits -- and the risks -- of quieter traffic. Two acoustics experts, Klaus Genuit and Rene Weinandy, will present their work studying acoustic vehicle alerting systems, or AVAS, at the 177th ASA Meeting, May 13-17.

Locating a Shooter from the First Shot via Cellphone

Acoustical Society of America (ASA)

Militaries have worked hard to develop technologies that simultaneously protect soldiers' hearing and aid in battlefield communication. However, these don’t help if a soldier takes it off to assess the location of incoming gunfire. A French researcher has developed a proof of concept that uses the microphones in a TCAPS system to capture a shooter’s acoustic information and transmit this to a soldier’s smartphone to display shooter location in real time. He will present his shooter location research at the 177th ASA Meeting, May 13-17.

Quieter Intensive Care Units May Translate to Better Outcomes for Infants in New Study

Acoustical Society of America (ASA)

Excessive noise is widely known to have negative effects on health, and children in neonatal intensive care units are among the most vulnerable. Researchers have conducted one of the first studies linking the quiet time soundscape inside NICUs with infant health. The study examined the effects of quiet time implementation in multiple NICUs on infants up to 18 months after implementation. They will present their findings at the 177th ASA Meeting, May 13-17.

How Acoustics Detected Artillery in WWI

Acoustical Society of America (ASA)

During WWI, William Lawrence Bragg led the development of an acoustic method to locate enemy artillery, work that was so successful that it was soon used widely throughout the British army. The method, known as sound ranging, was also adopted by the U.S. Army when they joined the war, and earned Bragg a military decoration from the British armed forces. Bragg's story will be presented at the 177th ASA Meeting, May 13-17.

Hummingbird robot uses AI to soon go where drones can't

Purdue University

Your friendly neighborhood hummingbirds. If drones had this combo, they would be able to maneuver better through collapsed buildings and other cluttered spaces to find trapped victims.

Schedule for the Acoustical Society of America Press Conferences with Live Webcasts from Louisville

Acoustical Society of America (ASA)

Press conferences for the 177th Meeting of the Acoustical Society of America will be held Tuesday, May 14 in the Laffoon Room at the Galt House. The morning and afternoon press conferences will focus on research into human sounds and language learning, protecting wildlife from man-made obstacles and potentially helping authorities respond faster in an active shooting situation, as well as other discoveries in acoustics.

VisiBlends, a New Approach to Disrupt Visual Messaging

Columbia University School of Engineering and Applied Science

To help non-professionals create visual blends for their news and PSAs, Columbia Engineering researchers have developed VisiBlends, a flexible, user-friendly platform that transforms the creative brainstorming activity into a search function, and enables a statistically higher output of visually blended images. The VisiBlends platform combines a series of human steps or “microtasks” with AI and computational techniques. Crowd-sourcing is a key component of the system enabling groups of people to collaborate, either together or off-site.
