Neural Network Helps Detect Gunshots From Illegal Rainforest Poaching

Proposed model filters and verifies signals among a network of microphones to reduce false positives for gunshot detectors #ASA_ASJ2025 #ASA189

HONOLULU, Dec. 2, 2025 — Wildlife poaching remains a major conservation concern. Technological advancements have enabled webs of acoustic sensors to be deployed throughout rainforests, creating the possibility of real-time alerts to the sounds of gun-based poaching.

But the belly of the rainforest is loud, and sorting through a constant influx of sound data is computationally demanding. Detectors can distinguish a loud bang from the whistles, chirps, and rasps of birds and bugs. However, they often conflate the sounds of branches cracking, trees falling, or water dripping with gunshot noises, resulting in a high percentage of false positives for gunshot detectors.

Naveen Dhar, along with collaborators from Cornell University’s K. Lisa Yang Center for Conservation Bioacoustics and Elephant Listening Project, aimed to develop a lightweight gunshot detection neural network that can accompany sensors and process signals in real-time to minimize false positives.

Dhar will present his model Tuesday, Dec. 2, at 3 p.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

The model works with autonomous recording units (ARUs), which are power-efficient microphones that capture continuous, long-term soundscapes. The proposed system utilizes a web of ARUs deployed across the forest, each performing real-time detection, with a central hub that handles more complex processing.

An initial scan filters all audio for “gunshot likely” signals and sends them to the ARU’s microprocessor, where the lightweight gunshot detection model lives. If confirmed as a gunshot by the microprocessor, the ARU passes the information to the central hub, initiating data collection from other devices in the web.

By determining if other sensors also hear a “gunshot likely” noise, the central hub then decides whether the event was a true gunshot or a potential false positive. If it determines a true positive, the central hub collates audio files from each sensor, allowing it to pinpoint the location of the gunshot and alert rangers with coordinates for immediate poaching intervention.

“Down the road, the device can be used as a tool for rangers and conservation managers, providing accurate and verifiable alerts for on-the-ground intervention along with low-latency data on the spatiotemporal trends of poachers,” said Dhar.

He plans to expand the model to detect the type of gun that fires each gunshot and other anthropogenic activities, such as chainsaws or trucks, before field-testing the system, which is currently under development.

“I hope the device can coalesce with Internet of Things infrastructure innovations and cost reduction of materials to produce a low-cost, open-source framework for real-time detection usable in any part of the globe,” said Dhar.

To Bop or To Sway? The Music Will Tell You

Specific musical features have the power to make people bounce or sway. #ASA_ASJ2025 #ASA189

HONOLULU, Dec. 2, 2025 — Some music is for grooving: It evokes spontaneous dancing, like head bopping, jumping, or arm swinging. Other music is for swaying, or for crying, or for slow dancing. Music makes people move, but whether musicians intentionally induce specific movements with their compositions, such as vertical bouncing or horizontal swaying, or what musical features would contribute to these distinctions, is more complex.

Shimpei Ikegami, an associate professor at Showa Women’s University, sought to understand how musicians express intended bodily movement directions using specific acoustic features.

“It’s almost magical how something we hear with our ears can influence our entire body. In Japan, we even have terms to describe distinct rhythmic feelings to music,” Ikegami said.

Ikegami will present his musical results Tuesday, Dec. 2, at 2:55 p.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

Four professional pop musicians composed short musical excerpts intended to elicit either “tate-nori” (vertical, up-and-down movement), “yoko-nori” (horizontal, side-to-side movement), or neither movement type.

Ikegami quantified the acoustic characteristics of the excerpts, measuring features such as loudness, beat clarity, rhythm complexity, and timbre. By comparing the prominence of features across intended-movement conditions, he found that vertical “bop” music was characterized by a clearer beat and percussive sounds, fueling listeners with the rush of high-energy workout songs. In contrast, horizontal “sway” excerpts were smoother and included less percussive sounds, creating a mellow and atmospheric musical impression. In a listener-rating experiment, participants heard each excerpt and rated the extent to which it made them feel like moving vertically and horizontally. Ikegami found that the listeners’ directional dancing inclinations matched the musicians’ intended expressions.

Ikegami’s findings suggest that the way musicians express certain qualities of danceability is specific and quantifiable. He aims to further explore commonalities and differences between musical profiles that induce vertical versus horizontal bodily movement.

“In the immediate future, I am investigating the psychological impressions — how the music is perceived by listeners. I am also deeply interested in cultural differences in these phenomena,” said Ikegami. “I believe that advancing my understanding of how music influences our body movements could be beneficial in fields such as health care, rehabilitation, and education.”

Making Quieter Dental Drills to Reduce Dental Anxiety

By studying the aeroacoustics of a dental drill, researchers can pinpoint the anxiety-causing sounds and design drills to lessen them. #ASA_ASJ2025 #ASA189

HONOLULU, Dec. 2, 2025 — Dental anxiety, also known as odontophobia, prevents people from getting their regular cleanings and keeping up with necessary dental hygiene.

One aspect of the anxiety comes from the sound of the dental drill, which makes a high-pitched whining sound. As a dentist, Tomomi Yamada has witnessed discomfort and fear in her patients firsthand.

“Originally, I was doing research on dental materials, but I realized that almost no one — not even dentists — was tackling this sound problem scientifically,” Yamada said.

Yamada, an assistant professor at the University of Osaka’s graduate school of dentistry, will present her work Tuesday, Dec. 2, at 8:20 a.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

To understand the aerodynamics of the drill, Yamada and her collaborators from the University of Osaka, Kobe University, and National Cheng Kung University used Japan’s flagship supercomputer to conduct large-scale aeroacoustics simulations. They analyzed the internal and external airflow of the dental drill, which is powered by compressed air and rotates at about 320,000 revolutions per minute.

From these simulations, they were able to visualize how air moves through and around the drill to create the noise.

“Our research showed that just making the drill quieter isn’t enough to make the sound less unpleasant,” Yamada said. “What really matters is improving its sound quality.”

The researchers also tested the psychological effects of the dental drill, which can generate high-pitched sounds reaching nearly 20 kilohertz, with children and adults. They found that younger listeners had different reactions to the drill, perceiving the sounds as louder and more unpleasant.

“This indicates that children’s fear of dental sounds is not merely psychological but also physiological in nature,” said Yamada. “Children truly hear these sounds differently, so their fear of dental treatment is a genuine sensory response, not just imagination.”

To address this, Yamada and her colleagues are working on optimizing the blade geometry and exhaust port of the drill to minimize the noise while maintaining the performance.

To get the dental industry to adopt this new technology, achieving a balance between the device’s performance and safety is key, since a quieter drill won’t necessarily get the job done.

“Moving forward, we hope to work with dental manufacturers through industry–academia partnerships, progressing toward commercialization after completing the necessary regulatory and durability testing,” Yamada said.

Elephant Seals Recognize Their Rivals From Years Prior

Male elephant seals respond to recorded calls of their old rivals, demonstrating lasting familiarity. #ASA_ASJ2025 #ASA189

HONOLULU, Dec. 1, 2025 — How would you react if you overheard the voice of a long-lost friend or old co-worker? Chances are, just the sound of their voice will bring back memories of times you spent together. Humans are not the only animals that can remember the voices of their old acquaintances. Elephant seals, too, can remember the calls of their rivals even a year later.

Caroline Casey, research scientist and adjunct professor at the University of California, Santa Cruz, will present her team’s research on elephant seal memory Monday, Dec. 1, at 2:45 p.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

Casey and her team have spent over a decade studying the seals on Año Nuevo Island off the coast of California. They have observed male elephant seals engaging in dominance displays year after year, and it led them to wonder if the seals remembered their past bouts.

“Male elephant seals come back to the exact same breeding location year after year and engage in competitive interactions with a number of familiar individuals,” said Casey. “It would make sense, then, that they would retain some memory of past rivals over multiple seasons.”

To test this, the team would find a male seal returning to the island at the start of the mating season and play recorded calls from his old rivals.

“When males heard their most familiar dominant rival from last year, they tended to orient faster, exhibit a faster posture change, and often would retreat from the speaker,” said Casey. “Their responses were less severe when they were presented with their subordinate rival from the previous season, and sometimes they would even approach the speaker.”

They also played calls recorded at other colonies, observing that these unfamiliar calls elicited a much smaller response from the seals. This proved that the seals were not just responding to random strangers but actually recognizing and remembering individuals they had met the year prior.

The researchers are continuing to study elephant seal reproductive behaviors.

“Right now, we are working on a project evaluating the traits that lead to eventual reproductive success in male elephant seals,” said Casey. “Essentially, what does it take to become an alpha seal? We are measuring lots of different aspects of behavior and physiology and linking it to true reproductive success in this species.”

Developing a New Electric Vehicle Sound

Employing low-frequency noise can help electric vehicles stand out in busy environments. #ASA_ASJ2025 #ASA189

HONOLULU, Dec. 1, 2025 — One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design their vehicles so they emit sounds at low speeds to alert pedestrians to their presence.

However, aside from some basic regulations regarding volume, automakers are free to choose whatever noise they wish their vehicles to emit. This freedom gives researchers a unique opportunity to design custom sounds to maximize their effectiveness.

Graduate student Mei Suzuki will present her team’s efforts to design custom approach sounds for electric vehicles Monday, Dec. 1, at 2:35 p.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

To test their library of created sounds, the team played them to volunteers, both in a studio and in real road conditions. They then asked the volunteers to rate each based on criteria such as “The sound has a sense of urgency” and “The sound is easy to notice.” The noises were then ranked based on this feedback.

They found the best performer was a version of pink noise — a type of noise dominated by lower-frequency notes.

“The reason this sound stimulus was rated highest was its strong low-frequency components and its similarity to automotive running noise,” said Suzuki.

This low-frequency noise distribution was less susceptible to being drowned out by other sources of ambient noise, which meant that approaching vehicles could be heard clearly by the volunteers in all conditions.

The researchers are planning to introduce similar sounds for electric bicycles, e-scooters, and other small lightweight mobility devices.

“Starting this year, we are conducting research on the sound design of approach warning sounds specifically for micromobility devices,” said Suzuki. “Since research on approach warning sounds for micromobility devices is largely unexplored, we believe this could contribute to reducing collisions involving pedestrians and visually impaired individuals.”
