NEW ORLEANS, May 23, 2025 – When children are dropped off at a school or day care for the first time, there can be a lot of feelings and sometimes meltdowns caused by being separated from parents, meeting new people, and hearing new noises. Could the architecture of the room help to soothe at least some of the children’s concerns?

“Classrooms without any sound absorption are the majority in Japan,” said Ikuri Matsuoka, a master’s student at Kumamoto University in Japan. “My motivation was to make people aware of the importance of acoustics in classrooms because in Japan, there are no standards or guidelines for acoustic design of preschool and school classrooms.”

Children in the process of developing language and speech can have a hard time listening, and so a classroom with lots of noise and reverberation can disturb communication and cause them to talk louder.

“We expect that preschool children entering school for the first time normally feel stressed by the difficulty of verbal communication,” Matsuoka said. “Therefore, this study examined whether sound absorption could mitigate such adverse effects.”

To test the effect of sound absorption on children’s noise, Matsuoka installed polyester fiberboard, a type of sound-absorbing material, onto one classroom’s ceiling and compared it to another without any.

Matsuoka will present their findings Friday, May 23, at 1:40 p.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

Matsuoka analyzed the indoor activities using video and audio to determine noise levels and the number of times the children cried. After six months, Matsuoka found that children were louder in the room without the insulation.

“During the experiment, I interviewed the four teachers in the four classes several times,” Matsuoka said. “Three of the four teachers answered that they felt the reverberation had changed, and one of them, a veteran teacher with 25 years of experience, answered that she felt clearly more comfortable talking to the children.”

To complement their results, Matsuoka and their professor also used artificial intelligence and machine learning to analyze the data automatically. They used an acoustic event detection method to identify children’s crying instead of manually scrubbing through the data. This work will also be presented during a session on “Materials for Sound Absorption, Diffusion, and Transmission Loss” on Friday, May 23, at 1:00 p.m. CT.

“We expect that machine learning will be necessary for long-term observations,” Matsuoka said. “From our research, we hope that those involved in both the child care and architectural fields recognize how important it is to have reduced reverberation that mitigate noisy atmosphere and promote clear verbal communication for children.”

NEW ORLEANS, May 22, 2025 – Coral reefs are vital to marine biodiversity, but their livelihood is under threat due to climate instability and the impacts of human activities.

Rehabilitating marine environments requires innovative solutions. Océane Boulais, a doctoral student at the Scripps Institution of Oceanography, studies one of these potential solutions: the impacts of acoustics on coral larval recruitment and settlement.

After spawning, coral larvae drift or swim through the water column, seeking suitable sites to find a home to attach to along the ocean floor.

“Multiple chemical compounds have already been identified as environmental cues that stimulate this settling behavior, presumably by indicating to the larvae when other successful-settled coral structures are nearby,” said Boulais. “A growing body of evidence over the past 20 years is also finding that sound may be another such cue.”

Healthy reefs are acoustically rich environments, filled with fish croaks and shrimp snaps. Boulais and their collaborators mimicked these sound environments to study the effects of sounds on 19 artificial coral settlement modules placed in Kāneʻohe Bay, Oahu, Hawaii. The researchers recorded audio near a vibrant reef, which they replayed at various distances from their artificial microhabitats. The artificial microhabitats were coated with a bacteria designed to induce larval settlement, creating a suitable habitat for attracting coral larvae.

Boulais will present details on their findings about the impacts sound has on coral larvae Thursday, May 22, at 9:20 a.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23. Notably, there were significant increases in coral settlement close to the speakers.

The researchers are planning an additional data deployment in the summer of 2025. Boulais said they hope to ultimately develop scalable strategies to study larger reef structures with audiovisual remote sensing tools, using low-cost cameras for continuously monitoring the reef’s biodiversity.

“Innovative, interdisciplinary approaches — combining science, technology, and creativity — can offer powerful solutions to pressing environmental challenges like coral reef degradation,” Boulais said. “Ultimately, I hope this research inspires both urgency and hope for the future of coral reefs.”

Re-Creating the Sounds of an Underground City #ASA188

Simulating the soundscape of an ancient city can provide useful historical information for scholars.

NEW ORLEANS, May 21, 2025 – Have you ever walked through the ruins of an ancient city and wondered what life sounded like back then? So has Sezin Nas, a researcher of interior architecture and acoustics at Istanbul Galata University.

The ancient, underground city of Derinkuyu caught Nas’s eye early on. Located in modern-day Turkey, Derinkuyu was built underground to defend against invasion, protect its citizens from harsh weather, and safely store agricultural products. At its peak, it could hold up to 20,000 people. The city spanned seven levels underground, with four main ventilation channels and over 50,000 other smaller shafts

“There is a notable gap in the literature regarding the acoustic environment and soundscape of underground cities,” Nas said. “Studying the Derinkuyu underground city aimed to contribute both to the preservation of cultural heritage and to provide data that could inform the design of future underground urban spaces.”

“The integration of ventilation and communication functions within the same architectural elements is considered one of Derinkuyu’s most unique features,” Nas said. “This multifunctional use of the ventilation system strongly highlights the exceptional construction process of the site and plays a central role in shaping its soundscape.”

To re-create the ancient soundscape, Nas studied both the history of the city as well as its architecture. She analyzed three types of spaces — a church, a living area, and a kitchen. The room functions, sources of sounds, and even reverberations were considered when creating a 3D virtual soundscape that will eventually allow a listener to experience the sounds of the city.

Nas will present work on the soundscape of the ancient city of Derinkuyu on Wednesday, May 21, at 11:20 a.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

“Derinkuyu underground city is considered an interior environment on an urban scale, which distinguishes it from the open-space urban soundscapes,” Nas said. “Listening to the reconstructed soundscape provides insights into how sound influenced spatial experience, communication practices, and social organization within the underground city.”

Nas said Derinkuyu’s soundscape can inspire the design of future underground urban spaces. She hopes that, in general, soundscapes will be used in the future as systematic tools for studying history.

“This research also highlights the role of historical sound environments as an important and often overlooked component of cultural heritage,” Nas said.

Can Plants Hear Their Pollinators? #ASA188

Research suggests pollinator buzzing sounds lead plants to increase their nectar production.

media@aip.org

NEW ORLEANS, May 21, 2025 – When pollinators visit flowers, they produce a variety of characteristic sounds, from wing flapping during hovering, to landing and takeoff. However, these sounds are extremely small compared to other vibrations and acoustics of insect life, causing researchers to overlook these insects’ acoustic signals often related to wing and body buzzing.

Francesca Barbero, a professor of zoology at the University of Turin, and her collaborators — an interdisciplinary mix of entomologists, sound engineers, and plant physiologists from Spain and Australia — studied these signals to develop noninvasive and efficient methods for monitoring pollinator communities and their influences on plant biology and ecology.

Barbero will present her findings and their impacts on Wednesday, May 21, at 9 a.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

“Plant-pollinator coevolution has been studied primarily by assessing the production and perception of visual and olfactory cues, even though there is growing evidence that both insects and plants can sense and produce, or transmit, vibroacoustic signals,” said Barbero.

Barbero and her collaborators played recordings near growing snapdragons of the buzzing sounds produced by a Rhodanthidium sticticum bee (sometimes called a snail-shell bee) to monitor the flowers’ reactions. The researchers found that the sounds of bees, which are efficient snapdragon pollinators, led the snapdragons to increase their sugar and nectar volume, and even alter their gene expression that governs sugar transport and nectar production.

The flowers’ response may be a survival and coevolution strategy, especially if the plants can affect the time pollinators spend within their flowers to increase their fidelity.

“The ability to discriminate approaching pollinators based on their distinctive vibroacoustic signals could be an adaptive strategy for plants,” said Barbero. “By replying to their proper vibroacoustic signal — for instance, an efficient pollinator’s — plants could improve their reproductive success if their responses drive modifications in pollinator behavior.”

While it’s clear that buzzing sounds can trigger plants’ responses, it’s less clear whether plant acoustics can also influence insect behavior — for example, whether sounds from plants can draw in a suitable pollinator.

“If this response from insects is confirmed, sounds could be used to treat economically relevant plants and crops, and increase their pollinators’ attraction,” said Barbero.

The team is conducting ongoing analyses comparing snapdragon responses to other pollinators and nectar robbers.

“The multitude of ways plants can perceive both biotic factors — such as beneficial and harmful insects, other neighboring plants — and abiotic cues, like temperature, drought, and wind in their surroundings, is truly astonishing,” Barbero said.

The project, “Good Vibes: How do plants recognise and respond to pollinator vibroacoustic signals?” (grant RGP0003/2022), is funded by the Human Frontier Science Program and is a collaborative effort between the University of Turin, I²SysBio in Valencia, and the Centre for Audio, Acoustics and Vibration at the University of Technology Sydney.

Remotely Moving Objects Underwater Using Sound #ASA188

Acoustic metamaterial enables pushing, rotating, and more complex movements in 3D.

NEW ORLEANS, May 20, 2025 – Sound can do more than just provide a nice beat. Sound waves have been used for everything from mapping the seafloor to breaking apart kidney stones. Thanks to a unique material structure, researchers can now move and position objects underwater without ever touching them directly.

Dajun Zhang, a doctoral student at the University of Wisconsin-Madison, will present his work on developing a metamaterial for underwater acoustic manipulation Tuesday, May 20, at 3:20 p.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

A metamaterial is a composite material that exhibits unique properties due to its structure. Zhang’s metamaterial features a small sawtooth pattern on its surface, which allows adjacent speakers to exert different forces on the material based on how the sound waves reflect off it. By carefully targeting the floating or submerged metamaterial with precise sound waves, Zhang can push and rotate any object attached to it exactly as much as he wants.

Manipulating objects in water without touching them could make a lot of underwater work easier. It could also be used inside the human body, which is mostly water, for applications like remote surgery or drug delivery.

“Our metamaterial offers a method to apply different acoustic radiation forces on objects in liquid media, such as underwater robots and vehicles, parts for assembly, or medical devices and drugs,” said Zhang.

However, manufacturing underwater metamaterials with the correct properties for object manipulation is difficult, especially with conventional methods.

“Current fabrication methods for underwater metamaterials do not provide the resolution or material properties required and are usually very expensive,” said Zhang. “To solve this issue, I developed a new fabrication method. This method is not only low cost and easy to implement but also achieves high fabrication resolution and large acoustic impedance contrast with water, which are keys to underwater metamaterials.”

In tests, Zhang used his metamaterial to manipulate floating objects, such as wood, wax, and plastic foam, along with objects completely submerged underwater. He attached his metamaterial to each object and used acoustic waves to push, pull, and rotate them. With submerged objects, this technique gave him the ability to manipulate them in three dimensions.

Zhang plans to continue his work, developing a metamaterial patch that is smaller and more flexible. He hopes his work will lead to new uses in medicine and underwater robotics.

“Our research opens new opportunities for both underwater acoustic metamaterials and remote manipulation,” said Zhang. “Acoustic metamaterials and metasurfaces can now be used to generate forces remotely for underwater or in-body levitation, actuation, and manipulation applications.”

Reducing Underwater Noise When Installing Subsea Structures #ASA188

Constructing offshore windfarms is loud and disruptive to marine life.

NEW ORLEANS, May 20, 2025 – Offshore wind farms have the potential for large impacts on clean energy generation, as wind speeds are higher at sea than on land. However, this benefit comes at a high cost for marine life, which can suffer greatly during the installation of offshore wind foundations.

Junfei Li, from Purdue University, will present work on mitigating the noise pollution during monopile offshore wind farm installation Tuesday, May 20, at 1:00 p.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

“To build offshore wind farms, monopile foundations are commonly driven into the seabed with hydraulic impact hammers, generating strong noises that propagate 50 kilometers or more from the installation site, potentially inducing auditory injury and behavioral change in marine species,” said Li.

These deep foundations are crucial for physically supporting wind farms — and other structures — above the sea. Most current mitigation techniques are limited by high energy demands or challenges with transportation and deployment.

Li and his colleagues instead developed a metamaterial comprising of carefully arranged plates that trap air within and act as guides for the sound. With their metamaterial in place, sound from monopile installation can be reduced by 40 decibels, an improvement over the 25-decibel reduction of other methods. The material is modular and foldable, making its transport and deployment easy and inexpensive.

Li said the sounds created during these processes have wide-reaching impacts.

“The high-intensity, impulsive noise generated by pile driving has the potential to affect a range of wildlife — including marine and freshwater fish, sea turtles, and marine mammals,” said Li. “It may lead to a range of behavioral changes in marine mammals and may lead to auditory or physical injury in some species of fish.”

The researchers hope to scale up their technology for deployment in future offshore wind far constructions, as well as for monopiles used in bridge construction and oil drilling platforms.

“Human-generated underwater noise is a critical — yet often hidden — environmental stressor. It’s not just background sound; it actively harms marine life, affecting their ability to survive and thrive,” said Li. “We must acknowledge the severity of our acoustic impact on the underwater world and work toward reducing it.”
