  • This paper proposes acceptance limits for the nosie dose ratio of noise dosimeters. The ratio of the noise dose of a sound burst signal to the noise dose of the steady-state signal under the same amplitude, frequency, measurement duration and judgment standard sound level, i.e. the noise dose ratio, of a noise dosimeter is studied. The dependence of the noise dose ratio on the time average sound level (i.e. equivalent continuous sound level), repetitive tone burst response, repetition time, and the duration of a single tone burst is also studied. The acceptance limits were used as criteria to evaluate the performance of several noise dosimeters and the test results lay within the limits.
