Newswise: Air Bubbles Sound Climate Change's Impact on Glaciers #ASA181
23-Nov-2021 11:15 AM EST
Air Bubbles Sound Climate Change's Impact on Glaciers #ASA181
Acoustical Society of America (ASA)

Air trapped with ice below glacier surfaces becomes a compressed bubble-ice mixture that builds pressure during the long passage to the glacier terminus. The glacier ice holds ancient bubbles of air that can be up to 20 atmospheres of pressure and generate detectable sounds when they are released as the ice melts. Scientists can listen to the release of the air and potentially use the sounds to help them gauge the impact of climate change on the ice floes.

Killer Whales Lingering in Newly Melted Arctic Ocean #ASA181
Acoustical Society of America (ASA)

Killer whales will often travel to different areas to target varieties of prey. In a study including eight years of passive acoustic data, researchers monitored killer whale movements using acoustic tools, finding killer whales are spending more time than previously recorded in the Arctic Ocean, despite risks of ice entrapment there. Their readings indicate this change is directly following the decrease in sea ice in the area.

Lego Down! Focused Vibrations Knock Over Minifigures #ASA181
Acoustical Society of America (ASA)

To demonstrate the power of focused vibrations, researchers use speaker shakers to generate vibrations in a plate. They place Lego minifigures on the plate, choose a target, and measure the impulse response between each shaker and the target location. Playing that very response from the shakers, but reversed in time, creates sound waves that constructively interfere at the target minifigure. The focused energy knocks over the single Lego minifig without disrupting the surrounding minifigs.

During COVID-19 Lockdown, Emotional Well-Being Declined for Adults with Vision, Hearing Loss #ASA181
Acoustical Society of America (ASA)

During pandemic-induced isolation, researchers from the University of Minnesota surveyed older adults with vision loss, with hearing loss, or without either condition, asking the participants about their worries, well-being, and social isolation at six-week intervals. All three groups scored lower on a patient health questionnaire after the pandemic began; however, people with vision or hearing loss faced unique problems in lockdown. Disruptions to mobility systems affected people with low vision, and masks made conversations especially difficult for adults with hearing loss.

Newswise: Food Paradox Answer Shows How Ocean Life Survives #ASA181

Food Paradox Answer Shows How Ocean Life Survives #ASA181
Acoustical Society of America (ASA)

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways. Using active acoustics, researchers found the ocean is widely populated with narrow hotspots of activity. Traditionally, these hotspots are missed with conventional sampling tools, but locating them can provide dynamic layered maps of ocean life. The findings signify ocean food and biota as patchy, varying with depth and location, suggesting animals must find and exploit small-scale aggregations of resources.

Sing On: Certain Face Masks Don't Hinder Vocalists #ASA181
Acoustical Society of America (ASA)

Researchers observed a professional soprano singing with and without six types of masks and found masks effectively block aerosols, forcing the breath to exit at the sides. From there, the aerosols travel upward, rising with the upward flow of body heat from the singer. At low frequencies, masks reduced volume but did not have other effects on the singing. However, masks did reduce the power of higher frequencies, which made the enunciation of words less clear and altered the timbre. Masks had no effect on the pitch.

Dementia Creates Listening Issues in Quiet, Noisy Environments #ASA181
Acoustical Society of America (ASA)

Difficulty in understanding speech, especially in background noise, is a common concern for older adults. Using a word identification task in quiet and noisy conditions, researchers examined the impact of mild dementia on speech perception. They tested individuals with and without mild dementia and found that word identification scores of those without dementia were significantly better in all conditions, meaning people with mild dementia symptoms recalled fewer words in both quiet and noisy situations.

Stuttering Starts at Speech Initiation, Not Due to Impaired Motor Skills #ASA181
Acoustical Society of America (ASA)

Techniques in neuroimaging and neurocomputational modeling are leading to a much better understanding of brain function during speech and how stuttering arises. Inside the brain, one circuit initiates the desired speech in the basal ganglia, while another circuit coordinates the muscles needed to generate the speech. Stuttering stems from the initiation of speech, so only the first of the two circuits is impaired. This theory matches behavioral observations of stuttering.

Newswise: Echolocation Builds Prediction Models of Prey Movement

Echolocation Builds Prediction Models of Prey Movement
Acoustical Society of America (ASA)

Bats use their acoustical abilities to create discrete echo snapshots and build representations of their environments, producing sounds for echolocation through contracting the larynx or clicking their tongues before analyzing the returning echoes. This acoustic information facilitates navigation and foraging, often in total darkness. Echo snapshots provide interrupted sensory information about target insect trajectory to build prediction models of prey location, and by amalgamating representations of prey echoes, bats can determine prey distance, size, shape, and density.

Newswise: Adding Sound to Electric Vehicles Improves Pedestrian Safety #ASA181

Adding Sound to Electric Vehicles Improves Pedestrian Safety #ASA181
Acoustical Society of America (ASA)

Electric vehicles are so quiet they can create a safety concern. To address this, many governments have mandated artificial sounds be added. In the U.S., regulations require vehicle sounds to be detectable at certain distances for various speeds, and researchers have tested how well people detect electric vehicle sounds in terms of these requirements. Participants in the study were seated adjacent to a lane of the test facility and pressed a button upon hearing an approaching electric vehicle. This allowed the researchers to measure the probability of detection versus distance from the vehicle.

Build Your Own Office Podcast Studio #ASA181
Acoustical Society of America (ASA)

Converting newly emptied office spaces into podcast studios poses noise challenges not previously realized before hybrid offices began. Offices are less busy and less noisy, meaning recording spaces can be used more often, and newly empty private offices can become podcast studios. But existing spaces present multiple acoustic challenges -- single-glazed windows, nearby noise sources, and limited available surface area, to name a few. Experts recommend considering location, nearby noise sources, and ways to absorb sound to make a studio effective.

The Power of Peer influence: Harnessing Shifting Social Norms to Curb College Students’ Drinking
Research Society on Alcoholism

A pilot study at the University of Washington in Seattle has shown that messaging on shifting “drinking norms” could help curb intentions to use alcohol among college students. Young people’s drinking is known to be influenced by their (often erroneous) perceptions of how their peers drink. To date, social norms interventions on campuses have focused on correcting students’ overestimates of how much alcohol their peers are consuming. Such interventions reflect the current state of normative behavior, known as static norms. In contrast, dynamic norms emphasize that a behavioral norm is shifting over time. These norms could be important in health behavior interventions, given emerging evidence that people align their behavior with social norms that they anticipate being prevalent in the future, even more so than the current norm. The new study, reported in Alcoholism: Clinical and Experimental Research, tested the concept of integrating dynamic norms messaging into alcohol interventions.

Filtering Microplastics Trash from Water with Acoustic Waves #ASA181
Acoustical Society of America (ASA)

Filtering and removing the microplastics from water is a difficult task, but acoustic waves may provide a solution. Researchers have developed a filtration prototype that uses two speakers to create acoustic waves. The force produced by the waves separates the microplastics from the water by creating pressure on a tube of inflowing water. As the tube splits into three channels, the microplastic particles are pressed toward the center as the clean water flows toward the two outer channels.

Blood Bubbles Reveal Oxygen Levels #ASA181
Acoustical Society of America (ASA)

Researchers have developed microbubbles to acoustically detect blood oxygen levels, since the microbubble shells are altered by structural hemoglobin changes in response to oxygen. The gas filling of the microbubbles causes them to oscillate and vibrate when ultrasound is applied, scattering energy and generating an acoustic response that can be detected by a clinical ultrasound scanner. Preliminary results show a strong correlation between oxygen concentration and the acoustic bubble response.
