UrduWhen an offshore wind farm pops up, there is a period of noisy but well-studied and in most cases regulated construction. Once the turbines are operational, they provide a valuable source of renewable energy while emitting a constant lower level of sound.

On Mars, NASA’s Perseverance Rover’s Playlist Like No Other #ASA182
After more than a year of recording on the surface, the team reduced the data to a Martian playlist that features about five hours of sounds.
Turning Hearing Aids into Noise-Canceling Devices #ASA182
For someone using an assistive listening device in a crowded place, it might make little difference whether the device is on or off. Nearby conversation directed at the user might be drowned out by distant conversation between other people, ambient noise from the environment, or music or speech piped through a loudspeaker system.
Corey and his colleagues worked to eliminate at least one source of noise, the one emanating from loudspeakers or other broadcast systems.
Snap, Crackle, Pop: Healthy Coral Reefs Brimming with Noise #ASA182
Altogether, the hundreds of thousands of animals living in the reef sound like static on the radio, or the snap, crackle, and pop of a bowl of Rice Krispies as you pour milk on the cereal, when the coral reef is healthy. The sound changes for reefs that are not healthy, becoming quieter and less diverse.
Explosions Help Probe Elusive Atmospheric Waves #ASA182
Infrasound waves can probe some of the most complex weather patterns hidden to normal observations, but finding a powerful enough source of infrasound waves can be a challenge unless there is a munitions factory nearby.
Ultrasound-Assisted Laser Technique Vaporizes Artery Plaque #ASA182
Atherosclerosis, a buildup of plaque, can lead to heart disease, artery disease, and chronic kidney disease and is traditionally treated by inserting and inflating a balloon to expand the artery. During the 182nd ASA Meeting, Rohit Singh, of the University of Kansas, will present a method that combines a low-power laser with ultrasound to remove arterial plaque safely and efficiently.
Going Virtual Hurts Student Career Prospects #ASA182
As in-person scientific meetings and gathering have been replaced by virtual meetings during the pandemic, students and young professionals are seeing career fairs and networking events transition into remote experiences that simply lack the same impact as getting together.
Listening Can Be Exhausting for Older Cochlear Implant Users #ASA182
In her presentation, “Aging effects on listening effort in cochlear-implant users,” Kristina DeRoy Milvae will discuss the results of two experiments that examined impacts on listening effort. The session will take place May 24 at 12:50 p.m. Eastern U.S. at the 182nd Meeting of the Acoustical Society of America at the Sheraton Denver Downtown Hotel.
Diverse Social Networks Reduce Accent Judgments #ASA182
Everyone has an accent. But the intelligibility of speech doesn’t just depend on that accent; it also depends on the listener. Visual cues and the diversity of the listener’s social network can impact their ability to understand and transcribe sentences after listening to the spoken word.
Sidekick Microbubbles Carry Anti-Cancer Drugs, Damage Tumor Vessels #ASA182
Naomi Matsuura, of the University of Toronto, and her team are adapting microbubbles to become more potent tools for cancer therapy. By shrinking the bubbles and directly loading them with anti-cancer drugs, the bubbles can lower the dose of free drug that is injected and diffuses into nontumor tissue in the body. This results in more targeted treatment and fewer side effects for the patient. Matsuura will discuss her team’s results in her presentation, “Ultrasound-stimulated, drug-loaded bubbles for cancer therapy,” as part of the 182nd Meeting of the Acoustical Society of America at the Sheraton Denver Downtown Hotel. The session will take place May 24 at 11:30 a.m. Eastern U.S.
DeepSqueak Tool Identifies Marine Mammal Calls #ASA182
As the size and number of acoustic datasets increase, accurately and quickly matching the bioacoustics signals to their corresponding sources becomes more challenging and important. This is especially difficult in noisy, natural acoustic environments. At the 182nd ASA Meeting, Elizabeth Ferguson, from Ocean Science Analytics, will describe how DeepSqueak, a deep learning tool, can classify underwater acoustic signals. It uses deep neural network image recognition and classification methods to determine the important features within spectrograms, then match those features to specific sources.
Making Racetrack Noise Bearable with Physics #ASA182
Raceways can produce noise from many kinds of vehicles, such as race cars, street race cars, racing motorcycles, go-karts, monster trucks, and cheering spectators. During the 182nd ASA Meeting, Bonnie Schnitta, from SoundSense LLC, will discuss her efforts to reduce the noise in a Michigan neighborhood from a nearby raceway. She and her team examined several different types of barriers, including berms, acoustic barriers, or dense foliage, to block that noise from reaching surrounding houses and businesses.
