Noise System 4.5: Integrated Software for Professional Acoustic and Vibration Analysis
Noise System 4.5 is a comprehensive measurement and analysis software platform designed for engineers and technicians working in noise, vibration, and harshness (NVH) testing, environmental noise monitoring, and product sound quality evaluation. It turns a PC with compatible data acquisition hardware into a powerful, multi-channel real-time analyzer.
Core Function: Real-Time Signal Processing for Sound & Vibration
Its primary role is to acquire time-domain signals from microphones, accelerometers, and tachometers, and perform real-time frequency-domain analysis (FFT), order analysis, and sound level calculations to diagnose noise and vibration sources.
Key Functions:
-
Real-Time FFT & Octave Analysis: Performs fast Fourier transforms and fractional-octave band analysis in real-time for instant spectral visualization.
-
Sound Level & Statistical Metrics: Functions as a precision sound level meter, logging and reporting metrics like Leq, Lmax, Ln, and generating statistical distributions.
-
Order Tracking & Tachometer Processing: Isolates noise and vibration components related to rotational speed (orders) for analyzing motors, engines, and rotating machinery.
-
Advanced Post-Processing: Supports recording of time data for detailed off-line analysis, including sound quality metrics, spectrograms, and report generation.
