A new sound-based laser could measure gravity with unprecedented precision and reshape navigation technology. Since their introduction in the 1960s, lasers have fueled major advances in science and everyday technology, from supermarket scanners to eye surgery. Traditional lasers operate by controlling photons, which are particles of light. Over the past two decades, researchers have expanded [...]

You can now hear what a 300-year-old violin sounds like if you alter its wood and other factors.

Sonic booms are expected along the Central California coast late Saturday as SpaceX launches its Falcon 9 rocket into orbit.

The 190th meeting of the Acoustical Society of America is coming up on May 11-15, and each day will feature a wide range of newsworthy sessions about the science of sound. We've highlighted a few standout sessions here, and press releases for an additional selection of topics will be shared under embargo during the week of May 4. Conference highlights can be found on social media by searching the…

Scientific Reports, Published online: 30 April 2026; doi:10.1038/s41598-026-50850-2 Effects of silicon dioxide nanoparticles on the mechanical, acoustic and vibration damping properties of kenaf-fibre polyester composite panels

Apple is presenting new research at the annual International Conference on Acoustics, Speech and Signal Processing (ICASSP) , which takes place in person in Barcelona, Spain, from May 4 to 8. We are proud to again sponsor the conference, which brings together the scientific and industrial research communities focused on signal processing and its applications. Below is an overview of Apple’s parti…

Scientists have created a new kind of quantum device that can turn electricity into something unusual: tiny packets of sound known as phonons. This breakthrough could one day lead to “phonon lasers,” a new type of technology with possible uses in communication, sensing, and even medicine. The research was led by a team at McGill […] The post Scientists turn electricity into sound in breakthrough …

TL;DR: Most "acoustic" panels were designed for offices, not studios. They target speech frequencies (250 Hz to 4 kHz) because that's what offices need. Your studio bass problems sit below 100 Hz. Completely different job. These panels will make your room feel nicer, but they won't change what your speakers are actually doing in the low end. Real studio treatment needs at least six inches of abso…

While hearing loss is preventable with earplugs, they can be uncomfortable, and users often remove them despite the risks. In the Journal of the Acoustical Society of America, researchers advance the state of "meta-earplugs" by using Helmholtz resonators to tune sound waves in the ear canal. The earplugs have multiple resonators, each tuned to a different frequency, which helps target a range of …

More comfortable earplugs mean increased use and lower rates of hearing loss. The post Meta-Earplugs Reduce Booming Voice Effect, Low-Frequency Rumbling Sounds first appeared on Acoustics.org .

Respiratory diseases are common on poultry farms during spring and autumn. Due to the high density of the farm environment, an epidemic can spread very quickly and cause large-scale biological infections. Therefore, developing software capable of monitoring or providing early warnings of respiratory disease in chickens is very important because it helps prevent the spread of diseases and enhances…

This conceptual poster presents the theoretical foundations of resonance in mechanical systems and structures, demonstrating the definition of resonance as a mechanical property associated with the vibration of an object, governed by modal properties, damping, and coupling. We review common applications and extensions to parametric and nonlinear resonance, where applications span vibration isolat…

Want to take the easy route? Check out our QRD Diffuser Well Depth Calculator What is a quadratic residue diffuser? The Quadratic Residue Diffuser (QRD) was developed by an OG scientist, Manfred Schroeder. He made significant contributions to the science of sound, particularly in how it behaves in rooms like auditoriums and studios. Schroeder created the QRD as a way to deal with common sound iss…

Can you just mix on headphones? Technically yes — but the mixes won't be as good and your ears will pay the price. Here's why proper speakers in an acoustically treated space produce better results, faster, with less listener fatigue. More

Only a few seconds of sampling is enough to create an AI copy of a person’s voice, and researchers are unsure why they are so intelligible. The post AI Voices Are Easier to Understand than Human Voices first appeared on Acoustics.org .

Your phone can measure the speed of sound in two ways — this app makes use of your phone's hidden sensors to do it.

Speaker: Carmen Rosas-Pérez, Heriot-Watt University Wed 15th April 12:00 – 13:00 UK time. This seminar will be held in person in Newton 241 and online via Microsoft Teams. Abstract In the work presented in this seminar, neurodiversity, auraldiversity, and diversity in noise sensitivity are considered as factors that can lead to differences in sensory experiences […]
