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 technologies will impact the surrounding environments. In this episode, we talk with Joseph Haxel (Pacific Northwest National Laboratory), Christopher Bassett (University of Washington), Brian Polagye (University of Washington), and Kaus Raghukumar (Integral Consulting) about their research related to the noise produced by marine energy converters.Read the associated article: Joseph Haxel, Christopher Bassett, Brian Polagye, Kaustubha Raghukumar, and Cailene Gunn.

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 Trends and Challenges in Research and Practice, Francesco Aletta (University College London), Cynthia Tarlao (McGill University), Tin Oberman (University College London), and Andrew Mitchell (University College London), to discuss these changes, which range from developments in understanding indoor soundscapes, cultural dimensions of soundscape assessment, perceptual assessment tools, and the use of virtual technologies.

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 London) about their work to develop an ultrasonic tomography algorithm that can be used to assess fracture risk in bones, and, as a result, be used as a noninvasive way to diagnose osteoporosis.Associated paper:- Aaron Chung-Jukko and Peter Huthwaite.

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 relationship between words' sounds and their meanings. In this episode, we talk to two of the editors of the Special Issue on Iconicity and Sound Symbolism, Aleksandra Ćwiek and Susanne Fuchs (Leibniz-Centre General Linguistics), about research in the issue that examined these connections.

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 soundscapes. In this episode, we talk with Nima Zargarnezhad and Ingrid Johnsrude (Western University) about their research testing the accuracy of the "AudioDome," a device that using ambisonic panning to simulate soundscapes in the lab.Associated paper:- Nima Zargarnezhad, Bruno Mesquita, Ewan A Macpherson. and Ingrid Johnsrude.
