Title: On the use of acoustic particle velocity to face airborne sound insulation
Abstract: 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.
