The Noise Measurement’s Uncertainty is ±1.18 dB. The reported expanded uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%.
The reported noise measurement’s level is the mean of 10 repeated measurements at an environment with a temperature deviation of ±2 degrees Celsius. The uncertainty was estimated according to the method in UKAS Publication M 3003.
