• Real time monitoring software(Windows)
* 1/1 Octave (optional)
* NC Level (optional)

Best Practice of International Standards
Sound Analyzer
ST-15D meets the most up-to-date IEC and ANSI certifications.
These certifications represent the only and the highest globally standardized approach to testing, inspection, and conformity assessment.

Real-Time
1/3 Octave Band
Analysis
Analyzing a sound source by frequency basis is really time-consuming, this is where one-third of octave bands make the difference.
ST15D applies 1/3 octave band analysis.
The 1/3 octave analysis is carried out using real-time band-pass filtering with decimation technique. This allows complex sound to be split into smaller sections or bands which then produce detailed filter shapes to accurately specify noise source.


Locate Noise Source with GPS
Measure sound level, detect sound frequency spectrum in real time, and locate the source of sound from one device. The integrated GPS shows start and end-point of sound location details.

初步決定是否需要噪音計作評估:
-
兩人相隔2米距離,需要大聲呼喊才可溝通
-
器材屬於勞工署的高噪音機械名單內
-
在工作環境下產生耳鳴及耳壓不適
-
密閉空間內的高噪音環境 ( 機房、生產器械廠房)

勞工署規例第3(3) 條, 噪音評估報告
評估完成後的28天內,將副本送交勞工署
