This new PCB Piezotronics microphone meets the IEC 61094-4 standard for test and measurement microphones with a frequency range up to 16 kHz (±2 dB), the hearing range for most adults. It is ideal for general room acoustics measurements as well as testing in aircraft cabins, automobile interiors and for calculating transmission loss with different materials.
Random Incidence microphones are commonly used for general omni-directional sound pressure level measurements. Performance venues such as music auditoriums or church halls use these microphones for measurements that aid in acoustic room design. Strategic placement of the sound source, furniture, sound absorbing materials, etc., are all factored into a venue’s design and help make the sound quality more pleasing to the audience.
PCB carries a full complement of externally polarized and prepolarized condenser microphones and preamplifiers. Prepolarized microphones use standard coaxial cables and are ICP compatible (ICP is registered trademark of PCB Group, which uniquely identifies PCB’s sensors which incorporate built-in electronics), allowing power supplies to be shared with other ICP compatible products such as accelerometers. This compatibility provides a significant per-channel cost savings as well as reduces test set-up time.
The 377C20 Random Incidence Microphone is A2LA and ILAC accredited. All PCB products come with a “Total Customer Satisfaction” guarantee. Microphone model 377C20 is in stock and available for immediate shipment.
