This dose limit uses a 3-dB time-intensity tradeoff commonly referred to as the exchange rate or equal-energy rule: for every 3-dB increase in averaged noise exposure, the allowable exposure time is reduced by half.
- Understand Noise Exposure | Noise and Hearing Loss | CDCSound level is the noise level measurement at a given point in time. Time Weighted Average (TWA) is sound level averaged over an eight-hour period. Noise dose is the percent of allowable noise exposure a worker can have. A noise dose of 100% or more means that a worker has exceeded their daily limit for noise exposure.

- Noise-Induced Hearing Loss | Noise | CDC - Centers for Disease Control ...For each 3 dBA increase in noise level, NIOSH recommends reducing the exposure duration by half. This is called the exchange rate. Similarly, if the daily exposure is longer than 8 hours, the allowable noise level is lower. To learn more, see Table 1-1 of the Occupational noise exposure; criteria for a recommended standard.
- NIOSH Sound Level Meter App | Noise and Hearing Loss | CDCThe NIOSH Sound Level Meter (SLM) app measures workplace noise to determine if workers are exposed to hazardous noise. The free app combines the best features of professional sound levels meters and noise dosimeters into one simple tool.
