It turns out modulating the input admittance of a standard sound diffuser allows energy to be scattered in frequency and wavenumber harmonics, which really improved diffusion. Great work by Janghoon Kang! aip.scitation.org/doi/10.1063/5.…

Born approximation can be used for calculating the acoustic radiation force for acoustofluidic separation: doi.org/10.1121/2.0001… UT Mech Engineering #acoustics #PhysicalAcoustics

ACOUSTICS TODAY These researchers want to trick acoustic and elastic waves propagating in finite-size laboratories into behaving exactly like they would if they were propagating in much larger, extended media. Learn how: doi.org/10.1121/AT.202…

Join us this Friday at 12:30pm for another Byron Short Seminar featuring Prof. Vincent Tournat!

What if the dimension of “time” could be introduced into material parameters? A new #SciencePerspective takes a closer look at four-dimensional optics using time-varying metamaterials—and the diverse applications they could have. scim.ag/27r

As part of phononics2023.org we have a General Interest talk in Acoustics by Trevor Cox on 14 June. Drinks reception 17:15-18:00 and talk at 18:00. Attendance at the talk is free! Please register attendance: eventbrite.co.uk/e/a-celebratio… Hope to see you there and please retweet!

ACOUSTICS TODAY Alan James Lomax was one of (if not) the foremost ethnomusicologists of the twentieth century. Read about his work, including his recordings of Huddie “Lead Belly” Ledbetter, in this Sound Perspective: ow.ly/4UMh50P7Wyf #acoustics #WorldListeningDay

The World Through Sound: Acoustic Medium The material that the sound travels through is what we call the “acoustic medium,” and without an appropriate medium, sound cannot travel at all acousticstoday.org/6-%e2%80%a2-th…
