Measurements of the amplitude vac of the voltage oscillations (narrow-band noise) in NbSe3 as a function of sample length L (300 1/4m to 5 mm) and frequency (50 kHz to 10 MHz) show that vac varies as 1-exp(-L/3/4), where 3/4 is approximately 200 1/4m. For L exceeding 0.9 mm vac is practically L independent. Our data are consistent with the phase-slip model for the voltage oscillations.
