In the DOSE formula, what does C stand for?

• A. C = hours exposed
• B. C = concentration of sound
• C. C = cycles per second
• D. C = crew size

Answer: (A)

The essential idea is comparing how long you’re exposed to a given noise level with how long you’re allowed to be exposed at that level. The C in the DOSE formula represents the actual exposure time, measured in hours. It’s the duration of exposure during the work period. Dose is typically calculated as Dose (%) = (C / permissible exposure time) × 100, where the permissible time depends on the noise level. For example, if the permissible exposure at a certain level is 8 hours and you’re exposed for 4 hours, the dose is 50%. The other options don’t fit because they describe different aspects: the concentration of sound relates to intensity (dB), cycles per second is frequency, and crew size has no effect on noise dose.
