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.
The acoustics of political speech are known to be a powerful influencer of voter preferences, but vocal disorders can change the qualities of a person's speech, and voice scientists have found that this alters politicians' perceived charisma. The researchers examined two cases of politicians with vocal disorders -- Umberto Bossi and Luiz Inácio Lula da Silva -- and will present the findings at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, La.
Spending a night in the hospital is not only stressful, but also loud. The constant beeps, whirrs and alarms ascend to a cacophony that produces anything but a relaxing, restful environment. Researchers will summarize the limited number of studies available on hospital noise and discuss the different approaches health care facilities are taking to bring restful repose to patients across the country during the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, La.
Marine invertebrates are impacted by the rising levels of underwater noise produced by humans, but the production of underwater noise is not only difficult to control, but the direct effect on marine invertebrates can be challenging to observe or measure. Researchers will present results on the use of a standing wave tube to simulate and measure the effects of anthropogenic noise on marine invertebrates at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans.
If you have looked closely at a microwave's warnings or have experienced an accidental explosion, you know that certain foods pose a risk due to an increase in their internal pressure, and potatoes and hard-boiled eggs are among the most common culprits. Researchers from Charles M. Salter Associates will present their research on the sound pressures generated by exploding eggs at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, Louisiana.
An interdisciplinary team is using a covert sound-based approach, worthy of an avian CSI, to study the link between crows' calls and their behavior.
Low-emission vehicles are considered too quiet for hearing-impaired pedestrians, so the European Union is mandating that they be equipped with acoustic vehicle alerting systems. With these alert systems would come a marked increase in the amount of noise on the roads across Europe. During the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, researchers will present their work assessing the effectiveness of acoustic vehicle alerting systems and their downsides.
