Standard audiometry programme after first two tests. While these first two years of testing are clearly defined in L108, the subsequent programme is a little less well specified, however there is a standard system used for workplace screening audiometry. From now on the standard re-test frequency depends on the category of result:

Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.
