Sound Power — Intensity Method (Discrete Points)

This test uses a sound intensity probe to measure acoustic intensity at discrete points on a measurement surface, allowing determination of sound power levels without requiring a fully anechoic environment. The intensity-based approach is effective for characterizing noise sources in semi-reverberant or field conditions where traditional pressure-based methods are unreliable. It provides directional acoustic information and is valuable for source localization and acoustic modification assessment. Accreditation ensures proper probe calibration, measurement procedures, and data processing are maintained to standards.

What it measures

  • Sound intensity magnitude and direction (vector)
  • Sound power level by surface integration
  • A-weighted and frequency-weighted acoustic power
  • Sound radiation patterns from complex sources
