Noise Inspector is a portable/fixed dual-purpose environmental noise inspection instrument that integrates "precise measurement - intelligent recognition - remote control - law enforcement and evidence collection". Specially designed for environmental protection bureaus, urban management, housing and construction, transportation, industrial parks, and third-party testing agencies to help users quickly identify, locate, and dispose of excessive noise sources. 360 ° omnidirectional acoustic radar, combined with beamforming algorithm, provides sound source azimuth and sound pressure level within 1 second. Typical application scenarios: Mobile inspection of urban expressways and rail transit corridors; Continuous monitoring of construction at night; Track the noise trajectory of flights around the airport; Online monitoring of factory boundary noise in industrial parks.
