Find the sensitivity rating level (dB V/µbar) of a microphone with an output voltage of 11.25 mV and a sound pressure level of 85 dB. Sensitivity constitutes one of the principal characteristics of a ...

A sensor developed by scientists at SINTEF’s MiNaLab, Trondheim, Norway, incorporates infrared optical technology to make audio microphones hypersensitive and more directional, reducing the impact of ...

A MEMS microphone IC is unique among Analog Devices, Inc., products in that its input is an acoustic pressure wave. For this reason, some specifications included in the data sheets for these parts may ...

Forbes contributors publish independent expert analyses and insights. Technology journalist specializing in audio, computing and Apple Macs. The new RØDE Video Mic GO II is a brilliant little shotgun ...

Scientists have developed a graphene-based microphone which is nearly 32 times more sensitive than microphones of standard nickel-based construction. "We wanted to show that graphene, although a ...

Graphene's ever-growing list of remarkable properties has seen many wide-reaching potential applications for the wonder material proposed, but actual demonstrations of real-world uses are still thin ...

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.

Maybe you, like any red-blooded American man, still harbor some rock star dreams. Or maybe your friends have grown tired of your impassioned, point-by-point tirades about how Game of Thrones books are ...

Understanding microphone specifications can help in selecting a model suitable for any particular application. One of these specs is sensitivity. This the open circuit voltage at the output of the mic ...
