ST-15D – Advanced Occupational Noise Measurements
Scarlet ST-15D integrates professional class-1 sound level monitoring with a GPS analyzer that meets IEC and ANSI international standards. It is fitted with one-third octave band filters for detailed sound analysis. Precisely measure sound level and detect noise source with one-device.
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.
Smart Software for Sound Data Management
Monitor real-time noise measurement data and export historical data for further analysis on your computer using Scarlet Sound software.
ScarletSound software is Windows PC-compatible. Install software on the computer and connect ST-15D to computer via USB cable.
Additional Features
• Audio Recording – Record Sound Data and Save it into “WAVE” format
• Instant Data Printout – Directly print data reports with portable high speed printer
• Class 1 Calibration – Calibrate device accurately on your own using ST-120 calibrator
