Transducers:
loudspeakers
Output
signal:
•Particle velocity over a surface (volume velocity Q, m3/s)
•The
sound field reacts with an acoustical pressure p
•Depending
on the phase relationship between pressure and particle velocity, a certain
amount of sound power is radiated:
From
electrical quantities (voltage, current) to acoustical radiation (volume velocity Q, sound power W)
