The impulse measurement of acoustic impedance is based on the Fourier transforms of sound pressure pulses. The new type of the source of the acoustic volume-velocity pulses with a high internal acoustic impedance is described. A lot of practical horns were measured: exponential, multicellular, rectangular and folded horns. The power range of horns is 100 W to 3000 W. Complex and transfer acoustic impedance was measured for all types.
