Earplugs That Block Out All Sounds
A new 3D-printed earplug can absorb physiological sounds made by the body, potentially making it more acoustically comfortable to use than some commercially available earplugs. Continue reading
Identifying the Source of a Sound
Torben Pastore had careers in rock n’ roll, furniture design, and construction before beginning a research career in psychoacoustics. Now he investigates how humans perceive their acoustical surroundings. Continue reading
Ricocheting Waves Pinpoint an Object’s Location
An echo chamber captures small-scale information about an object without the need for up-close probing. Read more in APS Physics…
Tracking Forces with Sound
Acoustic emission from a ruptured liquid film reveals the forces that drive the liquid’s flow. Continue reading
A broad acoustic bandwidth helps listeners understand fragmented speech
High-frequency audibility is critical for understanding speech in crowded social settings. Continue reading
