After demonstrating a super-efficient, ultra-quiet leaf blower, Whisper Aero has secured funding to fit its WhisperDrive propulsion technology to a glider and begin test flights. Its innovative ducted fans promise extreme efficiency and low noise.

You may not think of fish as being noisy, but they can actually be a pretty vocal bunch. A new AI system is able to quickly identify specific fish calls within general reef noise, allowing scientists to better track local populations.

Electricity is chaotic, and we normally need to constrain it to wires and circuits to make use of it. Scientists in Europe and Canada have now managed to guide sparks through thin air and even around obstacles using ultrasound waves.

Way back in 2016, Yamaha built an actuator into its new TransAcoustic line of acoustic guitars that produced reverb and chorus through the sound hole. The second generation has just launched, and now includes a built-in looper.

A little over 10 years ago, a Phoenix-based startup treated acoustic pickers to a bunch of effects directly through the sound hole courtesy of the smartphone-sized ToneWoodAmp. Now the much-improved second generation device has launched.

John Lennon's 1964 Framus 5/024 Hootenanny famously played on the title track of The Beatles' 1965 album Help! – and believed lost for more than 50 years – is heading to auction next month, where it's expected to break records.

Because GPS doesn't work underwater, divers usually can't track their real-time position on a digital map. The new Diver Navigation System (DNS) gets around that problem, however, using both floating and wearable acoustic transponders.

Around this time last year, as part of its 50-year celebrations, California's Drum Workshop announced the upcoming release of an acoustic/electronic drum set featuring wireless triggering tech. Now the DWe convertible kits have officially launched.

Fender has pulled back the stage curtain on the Highway Series acoustic guitars in dreadnought or parlor guises, each slimmed down for a more comfortable playing experience and "finely tuned for performance on and off the stage."

Guiding lasers where they need to go is a key part of optics systems, and now engineers at DESY have developed a way to bend laser beams without anything touching them. The light is deflected using an invisible grating made of air shaped by acoustics.

We first got our hands on Lava's oddball carbon-fiber Me 2 smart guitar back in 2021, which was followed by a new model later that year. Now the company has announced the fourth generation, adding a spruce option plus a more affordable Play flavor.

Boss has added an interesting new amplifier to its acoustic range. The AC-22LX battery-powered compact amplifier for acoustic instruments rocks Air Feel processing for faithful natural tones at performance volumes.
