Transducers:
microphones
Output
signal:
voltage
(Volts), current (Amperes) or charge (Coulombs)
From
acoustic pressure and particle velocity to physical (electrical) quantities
Pressure
microphones (related with acoustic
pressure)
Velocity
microphones (related with particle velocity)
Hybrid microphones (a proper combination of both
quantities)
From omnidirectional (100 p and 0
v) to figure of eight (0 p and 100 v)
