When 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.

Irvine, Calif., May 26, 2022 – When a driverless car is in motion, one faulty decision by its collision-avoidance system can lead to disaster, but researchers at the University of California, Irvine have identified another possible risk: Autonomous vehicles can be tricked into an abrupt halt or other undesired driving behavior by the placement of an ordinary object on the side of the road.

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.

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.

As part of the 182nd ASA Meeting, Luisa Still, of Sensor Data and Information Fusion, will discuss the important factors in determining shooter localization accuracy. In an urban setting, buildings or other obstacles can reflect, refract, and absorb sound waves, which can severely impact said accuracy. Preemptively predicting this is crucial for mission planning in urban environments. Still and her team used geometric considerations to model acoustic sensor measurements. This modeling, combined with information on sensor characteristics, the sensor-to-shooter geometry, and the urban environment, allowed them to calculate a prediction of localization accuracy.

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.

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.

Scientists from Washington University in St. Louis are helping to recover gases from a container of lunar soil that astronauts collected and sealed under vacuum on the surface of the Moon in 1972. The effort is part of NASA’s Apollo Next Generation Sample Analysis (ANGSA) initiative. Preliminary science results will be discussed during the Lunar and Planetary Science Conference, which will be held in Houston March 7-11.

University of Washington-led research suggests moon jellies are feasting on zooplankton, the various tiny animals that drift with the currents, in the bays they inhabit. This could affect other hungry marine life, like juvenile salmon or herring — especially if predictions are correct and climate change will favor fast-growing jellyfish.

New research shows turtles can experience temporary hearing loss from an excess of underwater noise. This phenomenon, previously noted in other marine animals such as dolphins and fish, was not widely understood for reptiles and underscores another potential risk for aquatic turtles. This high volume of sound, referred to as underwater noise pollution, can be caused by passing ships and offshore construction.
