SensiBel has created a couple of evaluation kits for its tiny SBM100B laser-based microphones. Evaluation kit Aurora (right) has two microphones and is intended to be used for stereo recording ...

David Schwartz, who laid the foundation for MP3 with his undergraduate and Ph.D. work in the 80s, has another big idea: a microphone that uses lasers and smoke to detect the minute variations in air ...

Researchers at the National Institute of Standards and Technology (NIST) have conducted the first demonstration of a faster and more accurate way to calibrate certain kinds of microphones. The ...

Online conferences have become essential to work. However, these meetings become annoying if the audio quality is noisy due to poor performance of the microphones. This is also the daily experience of ...

Microphone calibration is an important issue for noise monitoring stations, sound power measurement systems and audiometric equipment, among other applications. Traditional calibration methods can ...

This tutorial wont be the most practical recording setup you have ever used, but it is an interesting bit of science and a great DIY project. It is a simple laser listening device that will allow you ...

This kind of sonic isolation is extremely difficult even for high-end audio microphones, so to be able to achieve it using nothing but two cameras and a laser? It feels a bit like black magic. But the ...

Laser microphones have been around since the Cold War. Back in those days, they were a favorite tool of the KGB – allowing spies to listen in on what was being said in a room from a safe distance.

This just may be the coolest way to eavesdrop on a conversation. You can now build your own Clear-and-Present-Danger-esque laser microphone using inexpensive materials: By reflecting any type of laser ...
