• Resumen

  • Airborne sound insulation testing by means of acoustic intensity is a versatile alternative to sound pressure classical methods. An extension of traditional p-p intensity-based method is used, assessing sound power in both sides of a sample under test. Direct particle velocity measurements let a proper estimation of walls transmission lost when having flanking contributions and complex sound fields. Pressure, velocity, and intensity mapping are provided to research sound power through a building element. Results are compared with ISO 10140 standard testing. An analysis of method benefits and drawbacks, and future research lines are presented.
