Suitable for general room acoustics measurements as well as testing in aircraft cabins, automobile interiors, and calculating transmission loss with different materials, the model 377C20 random incidence microphone meets the IEC 61094-4 standard for test and measurement microphones with a frequency range up to 16 kHz (±2dB). 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. The 377C20 random incidence microphone is A2LA and ILAC accredited. A datasheet conveniently awaits at http://www.pcb.com/contentstore/docs/PCB_Corporate/Vibration/Products/Specsheets/377C20_NR.pdf
