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.
