Noise monitoring system
Harmony NM73
A system that consists of an automatic noise measuring device, a transmission device,
a computer system, and operation analysis software, and provides information such as noise level, location,
and device status for each branch in real time to provide accurate data necessary for establishing environmental noise-related policies.
Aircraft noise continuous measuring equipment(Addition of automatic aircraft identifying function)
Environmental noise continuous measuring equipment
IoT-based environmental noise continuous measuring equipment
Helicopter noise continuous measuring equipment
Analysis Software
Analysis processing of equivalent noise level of Leq, Lmax and Lmin every 5 minutes for measured data
Noise level management for each center frequency of 1/3 octave
When the noise exceeds the set value, it is saved as an actual noise file.
Can support charge injection calibration device
Frequency correction circuit setting: A, C and Z (Linear)
Measurement frequency band: 20 ~ 20kHz
Noise measurement range: 35dB ~ 135dB
