Active and Tunable Acoustic Metamaterials
As the study of acoustic metamaterials has progressed over the past couple of decades, research has shifted from focusing on the creation of materials with fixed structures to ones that are active or…
A Call for Diversity and Inclusion in Soundscape Research
One of the key components of soundscape research is the focus on the perspective of the listener. However, that perspective may shift depending on the listener's personal characteristics, their…
How Intelligible Are Cloned Voices?
You may have heard of deepfakes—AI clones of people used to create lifelike video and audio to manipulate an audience. AI cloning technology, however, has much broader applications than just…
Acoustic Thermometry to Assess Climate Change
How is climate change impacting the Arctic Ocean? It can be hard to track these changes, but researchers have been using acoustic signals transmitted beneath the ice to learn more. In this episode,…
Assessing Sediment Heterogeneity on Continental Shelves and Slopes
As anyone in ocean acoustics will tell you, sound is essential for much of the work done underwater, whether that be navigation, sensing objects, or passively monitoring wildlife. While much research…
Should AI tell you how to talk?
With the development of automatic speech recognition has come a new type of technology, designed to give the user advice on how to speak better. In this episode, we talk with Nicole Holliday…
Slurping, Snuffling, and Crunching: Assessing Misophonia Symptoms
Do you find the sound of people chewing unbearably annoying? Or perhaps you can't stand to be near folks who are typing on noisy keyboards, fidgeting with their pens, or rustling a plastic bag of…
Wave Phenomena in Vibroacoustic Systems
Manipulating the scattering of waves can allow engineers to achieve numerous goals, like reducing unwanted noise or eliminating potentially destructive vibrations in structures. In this episode, we…
POMA Student Paper Competition: New Orleans
In this episode, find out what the next generation of acousticians is researching! In this episode, we talk to the latest round of POMA Student Paper Competition winners, from the joint 188th meeting…
A New Way to Measure Bat Hearing
Studying bats' hearing can be tricky due to their small size, making certain styles of measurement used for larger echolocating mammals unavailable to researchers. In this episode, we talk to…
Sonic Deception in World War II
You may have heard of the "ghost army" of World War II—a set of rubber tanks used by the US Army to mimic active battlefields in Europe. What you may not know was the tanks were accompanied by an…
The Unique Acoustics of Traditional Chinese Interlocked Timber-Arched Covered Bridges
The traditional Chinese structure of the interlocked timber-arched covered bridge serves multiple purposes within Chinese culture—both as a physical connection between communities, but also as a…
The Eras of Taylor Swift's Changing Dialect
Longitudinal studies of how an individual's accent changes over the course of their life are hard to come by. Fortunately, Taylor Swift's decade-plus career-- and the numerous interviews she's given…
The Acoustic Impacts of Marine Energy Converters
In an effort to develop renewable energy, scientists have turned to the sun, the wind, and now the ocean. With these new forms of energy harvesting, considerations need to be made about how the new…
Advances in Soundscape
A lot has changed in the twelve years since JASA's first special issue on soundscape research. This episode, we talk to the editors of the recent special issue on Advances in Soundscape: Emerging…
A New Way to Diagnose Osteoporosis
Ultrasonic tomography has been applied in many fields, from geophysics to engineering, and now to medicine. In this episode, we talk with Aaron Chung-Jukko and Peter Huthwaite (Imperial College…
Iconicity and Sound Symbolism
For a long time, it was believed that words were mostly arbitrary symbols. However, with advances in our ability to study speech, it has become clear that we must reconsider the fundamental…
Reproducing Soundscapes with the AudioDome
Recreating the natural hearing experience has long challenged researchers who study auditory perception. Recently, ambisonic panning has been developed as a method to accurately reproduce…
An Archeoacoustic Look at Two Hindu Temples
Much of the research into the historical acoustics of worship spaces has focused on Christian churches or Islamic mosques. However, little is known about the acoustic history of Hindu worship spaces,…
Student Paper Competition: Environmentally Friendly Acoustic Design, Spatial Impulse Response Measurements, and Acoustic Spectrometers
