  • 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.

  • 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, despite Hinduism being the third largest religion in the world. Shashank Aswathanarayana and Braxton Boren (American University) share their efforts to fill this knowledge gap by studying the acoustics in Hindu temples from the 8th and 15th centuries. Associated paper: Shashank Aswathanarayana and Braxton Boren.

  • Student Paper Competition: Environmentally Friendly Acoustic Design, Spatial Impulse Response Measurements, and Acoustic Spectrometers
    This episode showcases the latest winners of the POMA Student Paper Competition: First, Jonathan Michael Broyles (University of Colorado, Boulder) discusses his database to help acoustical consultants design more environmentally friendly spaces. Next, John Latta (University of Nebraska - Lincoln) shares his work regarding spatial impulse response measurements. Finally, Michelle Ruth Crouse (California State University, Dominguez Hills) talks about the acoustic spectrometer she created using off-the-shelf parts. Associated papers:Jonathan Michael Broyles and Wil Srubar, III.

  • Large Venue Acoustics
    Large venues like amphitheaters and stadiums are used across the world for a variety of purposes, hosting everything from sporting events to concerts to large social gatherings and other events. The massive size of the spaces, alongside their multifaceted uses, however, mean their acoustic needs are quite different from those of smaller rooms or even concert halls. This episode, Gary W. Siebein (Siebein Associates, Inc.), Keely Siebein (Siebein Associates, Inc.), Jack Wrightson (Wrightson, Johnson, Haddon, & Williams, Inc.), and Joe Solway (Arup) discuss the unique considerations for designing these structures. Read the associated article: Gary W.

  • Things That Go Boom
    In this episode, we explore things that go boom: from volcanic eruptions to underwater ordinances to the (relatively) tiny explosions of gunshots. Thomas Blanford (University of New Hampshire) joins us as a cohost as we discuss the use of high-amplitude acoustic sources in research with three members of a special session on the topic from the Ottawa ASA meeting: Steve Beck (Beck Audio Forensics), Daniel Bowman (Pacific Northwest National Laboratories), and Andrew McNeese (University of Texas at Austin). Associated paper: Thomas E.
