Table 1 is for noise levels between 75 and  \n105 dB(A) for durations between 15 minutes and 12 hours, and Table 2 is for noise levels between 95 and 125 dB(A) for durations between 5 seconds and 10 minutes.  \nFor example, a task producing a noise level at the worker’s ear of 93 dB(A) that is done for two lots of 30 minutes in a shift ( [i.e. one](i.e. one) hour total) produces 80 noise exposure points. Another task with a noise level of 120 dB(A) for one minute during the shift produces 670 points.  \nThese points can be added (in the normal arithmetic way) to give the total exposure points for the shift. Table 3 is then used to convert the total points to the LAeq,8h.  \nIn the example above, if these were the only noisy tasks carried out by the worker, the points total is 750 and (from Table 3, rounding to the nearest whole decibel) the LAeq,8h for the worker is 94 dB(A) .  \nThis calculated LAeq,8h value can be compared with the exposure standard for noise i.e. LAeq,8h = 85 dB(A) . Additionally, noise exposure points can be used to prioritise the noise control program by showing which tasks make the greatest contribution to the total noise exposure.  \nIn the example above the worker’s LAeq,8h is greater than the standard, so noise control action is needed. Although it only lasts for one minute, the 120 dB(A) task contributes more than eight times as much as the other task to the total exposure and so should be the first one addressed.  \nIn this scheme the exposure standard for noise (LAeq,8h of 85 dB(A)) is 100 points.  \nNoise exposure level ready-reckoner – INFORMATION SHEET | 1  \nTable 1 Exposure points for 75–105 dB(A)/15 minutes — 12 hours  \n\n|  | Duration of exposure per shift |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| Sound level LAeq,TdB(A) | 15 min | 30 min | 1 h | 2 h | 4 h | 8 h | 10 h* | 12 h* |\n| 105 | 320 | 640 | 1270 | 2530 | 5060 | 10120 | 12650 | 15180 |\n| 104 | 250 | 500 | 1000 | 2010 | 4020 | 8040 | 10050 | 12060 |\n| 103 | 200 | 400 | 800 | 1600 | 3200 | 6400 | 8000 | 9600 |\n| 102 | 160 | 320 | 640 | 1270 | 2540 | 5070 | 6340 | 7600 |\n| 101 | 130 | 250 | 500 | 1010 | 2010 | 4030 | 5040 | 6040 |\n| 100 | 100 | 200 | 400 | 800 | 1600 | 3200 | 4000 | 4800 |\n| 99 | 80 | 160 | 320 | 640 | 1270 | 2540 | 3180 | 3810 |\n| 98 | 63 | 130 | 250 | 500 | 1010 | 2020 | 2520 | 3030 |\n| 97 | 50 | 100 | 200 | 400 | 800 | 1600 | 2000 | 2410 |\n| 96 | 40 | 80 | 160 | 320 | 640 | 1270 | 1590 | 1910 |\n| 95 | 32 | 63 | 130 | 250 | 510 | 1010 | 1260 | 1520 |\n| 94 | 25 | 50 | 100 | 200 | 400 | 800 | 1000 | 1210 |\n| 93 | 20 | 40 | 80 | 160 | 320 | 640 | 800 | 960 |\n| 92 | 16 | 32 | 63 | 130 | 250 | 510 | 630 | 760 |\n| 91 | 13 | 25 | 50 | 100 | 200 | 400 | 500 | 600 |\n| 90 | 10 | 20 | 40 | 80 | 160 | 320 | 400 | 480 |\n| 89 | 7.9 | 16 | 32 | 64 | 130 | 250 | 320 | 380 |\n| 88 | 6.3 | 13 | 25 | 50 | 100 | 200 | 250 | 300 |\n| 87 | 5.0 | 10 | 20 | 40 | 80 | 160 | 200 | 240 |\n| 86 | 4.0 | 8.0 | 16 | 32 | 64 | 130 | 160 | 190 |\n| 85 | 3.2 | 6.3 | 13 | 25 | 50 | 100 | 130 | 150 |\n| 84 | 2.5 | 5.0 | 10 | 20 | 40 | 80 | 100 | 120 |\n| 83 | 2.0 | 4.0 | 8.0 | 16 | 32 | 64 | 80 | 96 |\n| 82 | 1.6 | 3.2 | 6.3 | 13 | 25 | 51 | 63 | 76 |\n| 81 | 1.3 | 2.5 | 5.0 | 10 | 20 | 40 | 50 | 60 |\n| 80 | 1.0 | 2.0 | 4.0 | 8.0 | 16 | 32 | 40 | 48 |\n| 79 | 0.8 | 1.6 | 3.","cbCaidySGop88yAe","https://ap.wps.com/l/cbCaidySGop88yAe","pdf",431837,"English","# Noise exposure level ready-reckoner\n## How exposure points are calculated\n## Comparison to the noise exposure standard\n## Table 1: 75–105 dB(A) / 15 minutes — 12 hours\n## Table 2: 95–125 dB(A) / 5 seconds — 10 minutes","[{\"question\":\"How do the tables help calculate a worker’s LAeq,8h?\",\"answer\":\"Use the worker’s measured noise level and the time spent on each noisy task to read corresponding noise exposure points from the tables.
