A recalculation of the values contained in Annex B of the new ISO standard R1999: “Determination of occupational noise exposure and the estimation of noise-induced hearing impairment,” utilizing procedures specified in the standard and in its supporting documentation was conducted. Three calculation errors, which occurred in the supporting document and were perseverated into the standard, were identified. These errors are explained and a corrected version of Annex B is presented.
