Unveiling new strategies to improve future wireless underwater sensing networks for marine research and communication.
Through extensive listening and analysis of whale calls--which were recorded by a large collaboration of scientists over the past two decades-- Syracuse University researchers were able to pick up the slow gradual changes in sound production in the marine giants as they age. Looking at spectrograms of the calls, which provide visual representations of the sound, the research team could see the progression of vocal characteristics of the animals from calf throughout adulthood.
Sound waves generated by burbling lakes of lava atop some volcanoes point to greater odds of magmatic outbursts. This finding could provide advance warning to people who live near active volcanoes.
Bird-human actions can end in tragedy -- for bird as well as human. William & Mary professor John Swaddle believes technology and a solid understanding of bird behavior can make those tragedies less frequent, and is working on a pair of initiatives designed to minimize unpleasant results of bird-human interactions.
High-speed recordings of Egyptian fruit bats in flight show that instead of using a primitive form of echolocation, these animals actually use a technique recently developed by humans for surveillance and navigation.
Kyoto University Researcher find that some mechanosensitive genes are suppressed when subjected to audible sound.
NOAA scientists studying sounds made by Atlantic cod and haddock at spawning sites in the Gulf of Maine have found that vessel traffic noise is reducing the distance over which these animals can communicate with each other. As a result, daily behavior, feeding, mating, and socializing during critical biological periods for these commercially and ecologically important fish may be altered, according to a study published in Nature Scientific Reports.
Vocoded speech, or distorted speech that imitates voice transduction by a cochlear implant, is used throughout acoustic and auditory research to explore speech comprehension under various conditions. Researchers evaluated whether musicians had an advantage in understanding and reciting degraded speech as compared to nonmusicians, and they will present their work on the effect of musical experience on the ability to understand vocoded speech at the 174th ASA Meeting, Dec. 4-8, 2017.
Listening requires sensitive hearing and the ability to process information into cohesive meaning. Add everyday background noise and constant interruptions, and the ability to comprehend what is heard becomes that much more difficult. Audiology researchers at Auburn University have found that in such demanding environments, both children and adults depend more on their right ear for processing and retaining what they hear. They will present their work at the 174th ASA Meeting, Dec. 4-8.
The hauntingly beautiful 'wailing' sounds of early New Orleans jazz clarinets, often featured in brass bands or jazz funerals, are one of the most distinctive instrument styles in American music. The unique sound begs the question: what's behind incredible their range of sound and tonal variety? During the 174th ASA Meeting, Dec. 4-8, 2017, Michael G. White will deliver a special presentation about the distinguishing characteristics of the clarinet in early New Orleans jazz.
