The analysis model then calculates the equivalency factors.

Table 47.1 Permissible exposure limits (PEL), exchange rates, and other requirements for noise exposure according to nation

The table below shows the criterion levels (i.e., maximum permitted exposure levels for 8 hours) and the exchange rates used in different Canadian jurisdictions.

Table 1 also shows the noise exposure limit for extended shifts using both 5dB and 3dB exchange rates.

These two exchange rates, with criterion levels of 85 dB(A) and 90 dB(A), give two different sets of exposure guidelines, as Table 1A and 1B show.
