A study has found that playing a soundscape to a common, plant-promoting fungus found in soil caused it to grow more rapidly than fungi that weren’t exposed to sound. The novel ‘eco-acoustic’ approach has the potential to restore damaged ecosystems.Con… Continue reading Sound makes soil fungi bloom & could restore damaged ecosystems
Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would not only reduce battery waste but could also power m… Continue reading Battery-free sensor harnesses the power of speech
If you have multiple microphones in known locations, and can determine the time a sound arrives at each one, you can actually determine the location that sound is coming from. …read more Continue reading Localizing Fireworks Launches With A Raspberry Pi
When you’re out riding your bike, a horn can be a useful warning device to other road users and pedestrians alike. It can also be a source of fun and …read more Continue reading Digital Bike Horn Will Play Custom Sounds, Please Be Tasteful
The search for survivors at disaster sites is one of the most commonly suggested uses for drones. If those people are buried under debris, however, they won’t be visible from the air. That’s where LUCY comes in, as it could let drones locate survivors … Continue reading Drone-mounted LUCY tech has an ear for hidden disaster-site survivors
Table tennis is one of those sports that most people would likely assume is simply unplayable by the blind. An Australian student, however, is now using cameras and speakers to get unsighted individuals in on the ping pong action.Continue ReadingCatego… Continue reading Student-designed system could allow the blind to play table tennis
Who along with me, is not a fan of the DING sound that Windows makes when changing the Volume using the slider? The sound can be jarring to the ears of the listener, especially if they have attached an earphone. In this post, we will discuss how you ca… Continue reading Turn off DING sound when changing Volume in Windows 11
Noise-cancelling headphones are great for blocking out the loud talkers and chaotic coffee shops of the world, but what if there are certain sounds that you want to hear? That’s where the experimental new “semantic hearing” system could soon come in.Co… Continue reading “Semantic hearing” headphone tech keeps certain sounds from being blocked
Whisper Aero wants to revolutionize electric aviation with propulsion systems 100x quieter and 20% more efficient than anything else on the market. While it’s working on that, it’s thrown together a quiet, powerful, efficient leaf blower as a demo.Cont… Continue reading Ultra-quiet leaf blower uses electric aircraft technology
Before the invention of microelectromechanical system (MEMS) microphones, almost all microphones in cell phones and other electronics were a type of condenser microphone called the electret microphone. The fact that …read more Continue reading Low-Cost Electret Microphone Preamplifiers
