A newly developed fiber-optic microphone demonstrates how light-based sensing can overcome the limitations of conventional electronics in extreme environments.

Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound ...

They developed a unique sound-sensing design that uses a vibration-sensitive membrane and an internal glass micro-beam ...

How piezoelectric fibers can be used for acoustic sensing and audio output. The test arrangements employed to assess performance from different perspectives. The results of some of the tests along ...

The trouble with microphones is that they don’t just hear — they have to listen. Powering the mic and its signal processor means using energy, and energy means a battery, and a battery means charging.

Condenser microphones are sensitive and capture a wide range of frequencies, making them ideal for studio settings where background noise can be controlled. Dynamic microphones are less sensitive to ...
