WebThe noise exposure expressed as a percentage (%) of a fixed level for 8 hours. For example, if the noise limit is 85 dB and a person is exposed to a constant or equivalent sound pressure level of 85 dB for eight hours, then the result is a 100% noise dose. In the UK a 3dB Exchange Rate, or Q, is used. This means that a noise level WebNoise dose is an important matter that needs to be figured out based on (TWA) for 8 hours per day as tabulated in Table 2. From Fig 5, almost 38% of samples obtained 100% of noise dose, where TWA have reached permissible noise exposure limit, is 90 dB (A).
