Spectral considerations on the tone burst method for measuring transient distortion in loudspeakers

Spectral considerations on the conventional method for measuring the transient distortion in loudspeakers (repeated tone burst method) show that the result of the measurement is proportional to a weighted sum of the values of the complex transfer characteristic of the loudspeaker at the discrete frequencies f
0
and (2m-1) f
0
/2n where f
0
is the frequency of the pure tone from which the tone burst is formed, n is the number of full periods in each burst, and m = 1, 2, 3, . . .
