How to export and analyze the time-domain noise data of a personal sound exposure meter?
التاريخ:2025-12-19اقرأ:46
　　Personal sound exposure meterNot only can the equivalent sound level (LEX, 8h) be recorded, but high-resolution time-domain noise data can also be saved for in-depth analysis of noise exposure patterns.
1、 Data export steps:
Connecting devices: Pair the sound exposure meter with a computer/phone via USB, Bluetooth, or Wi Fi;
Launch supporting software such as Bruel&Kjaer's Noise Partner, Casella's CapSure, etc;
Synchronize data: The software automatically identifies the device and downloads the original file (usually in. csv or. xlsx format) containing parameters such as timestamp, instantaneous LAeq, peak LCpeak, etc.
2、 Key points of data analysis:
Time distribution chart: Draw the noise variation curve over time and identify high noise periods (such as the start stop of the press machine and forklift operations);
Statistics of exceedance events: Screen time periods exceeding 85 dB (A) or 140 dB (C peak) to assess the risk of hearing loss;
Task correlation analysis: Based on workers' work logs, correspond the peak noise level with specific operations (such as polishing, loading and unloading);
Compliance report generation: The software can automatically generate compliance reports that comply with OSHA 29 CFR 1910.95 or GBZ/T 189.8.


3、 Advanced applications:
Some devices support 1-second interval data recording, which can be used for spectrum analysis or machine fault diagnosis. It is recommended to import the data into Excel, MATLAB, or professional acoustic software (such as SoundCheck) for further processing.
Through systematic export and analysis, enterprises can not only meet regulatory requirements, but also accurately locate noise sources, develop targeted engineering control measures, and truly achieve a closed-loop occupational health management from monitoring to improvement.
