Prehistoric hunter-gatherers heard the elks painted on rocks talking

Researchers found that ancient rock painting sites by water generated strong echoes that could be heard by people approaching the site. The echoes allowed prehistoric hunter-gatherers to perceive their surroundings in a unique sensory environment. This discovery sheds light on the importance of sound reflections in past societies.

Cultivating a music studio to sound like an indoor forest #ASA183

Blackbird Studio C's ambient-anechoic portmanteau, ambichoic, reduces sound reflections, creating a balanced and immersive space for musicians and engineers. The studio's unique design utilizes primitive root diffusers to diffuse sound energy, resulting in a comfortable and engaging environment.

Davis Instruments Vantage Pro2 Weather Station

Davis Instruments Vantage Pro2 Weather Station offers research-grade local weather data for networked stations, campuses, and community observatories.

Optical microphone developed by CMU researchers sees sound like never before

A new camera system developed by Carnegie Mellon University researchers can reconstruct sound vibrations with extraordinary accuracy, capturing isolated audio without inference or a microphone. The dual-shutter vibration-sensing system uses two cameras and a laser to detect high-speed, low-amplitude surface vibrations.

Navigating the shallows

A team of researchers from the University of Tsukuba has developed a new approach for accurate underwater acoustic positioning in multipath environments. By using a database of signals and selectively removing reflected waves, they achieve centimeter-scale accuracy in object location, even in shallow waters.

The Rule of Two helps make spaces sound better

The Rule of Two method uses multiple measurements to collect reliable data, overcoming the limitations of single sine sweep techniques. This new approach will make it easier and faster to design rooms with optimal acoustic combinations, leading to better sound quality in various spaces.
