Acoustical Measurements

Acoustical Measurements

1. Sensors an actors

  • air-borne, e.g.
    • microphones
    • hot-wire anemometry
    • sound intensity probes
  • structure borne, e.g.
    • acceleration sensors
    • vibrational velocity sensors
    • force-sensor
  • shaker

2. Methods for the assessment of sound

  • sound pressure level
  • sound intensity level
  • sound power level

3. Determination of selected acoustic values

  • measurements regarding the sound absorption
    • Kundts-Tube
    • Large and small Reverberation Rooms
  • measurements regarding the sound insulation
    • diffuse field
    • Kundts-Tube
  • Flow resistivity

4. Selected acoustic measurement techniques

  • measurements of room and building acoustics
  • modal analysis
  • „Power-Injection “-method
