LinkedIn +

A new 0.5in random incidence microphone for noise reduction testing has been introduced by PCB Piezotronics.

Random incidence microphones, also known as diffuse field microphones, accurately measure multiple sounds that come from different directions, or sounds in rooms that have reflective surfaces.

The new model 377C20 microphone meets the IEC 61094-4 standard for test and measurement microphones with a frequency range up to 16 kHz (±2dB), which is the hearing range of most adults.

It is ideal for the measurement of general room acoustics as well as testing carried out in auto interiors, and for calculating transmission loss with different materials. The 377C20 is A2LA and ILAC accredited.
