Across Acoustics

The manufacturing and production of concrete construction building materials creates roughly 10% of global carbon emissions. As a result, architectural engineers are trying to find new ways to reduce the amount of concrete used in their buildings. Less concrete, though, can lead to some major ramifications in terms of the acoustics of a built space. In this episode, we talk to Jonathan Michael Bro...

The sound environment of a classroom can significantly impact the experience of students, particularly for young learners. Yet most research on primary school classroom acoustics has focused solely on removing all sound, even though some sounds may be beneficial to young students’ experience. In this interview, we talk to Chiara Visentin (University of Ferrara) about her research into the soundsca...

Associated paper: Kent L. Gee,   Grant W. Hart, Carson F. Cunningham,...

Noise can damage hearing in numerous ways: hearing loss, tinnitus, difficulty hearing in noisy settings, as well as other sound detection or sound processing deficits. In this episode, we talk to Colleen LePrell (UT Dallas School of Behavioral and Brain Sciences) and Odile Clavier (Creare), two editors of the recent Noise-Induced Hearing Disorders Special Issue of JASA . Learn about current clinic...

Could moths’ hearing be the key to figuring out how to localize sound with tiny microphones?  How do we prevent rocket launch noise from damaging the ship’s payload? Is it possible for algorithms to account for microphone arrays that don’t stay in a rigid structure? These are some questions considered by Acoustical Society students who won the latest round of the POMA Student Paper Competition fro...

Is there an ideal level for lead vocals compared to accompaniment in popular music? Researchers at University of Oldenburg investigated this question by analyzing the Billboard Hot 100 year-end list from 1946 to 2020 as well as Grammy award nominees from 1990 to 2020.  In this interview, author Kai Siedenburg discusses what his group learned about an important aspect of music mixing and the impact...

As mobile technology has evolved, allowing people to carry music, movies, books, and a host of other types of infotainment in their pockets, headphones have become more prevalent. However, in the 2010s, as smartphones became ubiquitous, headphone technology remained stuck twenty years in the past. In this episode, we talk to Sean Olive of Harman International about his research regarding the perce...
