Knowing your overall noise exposure is important, but it is not the only information you need when selecting the correct hearing protection.
To effectively protect hearing, it is essential to understand the noise levels across a range of specific frequencies. Noise energy should be measured at the following frequencies:
- 63Hz
- 125Hz
- 250Hz
- 500Hz
- 1000Hz
- 2000Hz
- 4000Hz
- 8000Hz
Once you have these measurements, you can use an Attenuation Chart to determine which ear defender will reduce the noise to below 80dB(A) at each of these frequencies. This ensures comprehensive protection across the full spectrum of potentially harmful noise.
Key points:
- Measuring overall noise levels is not enough to ensure adequate hearing protection.
- Noise energy must be assessed by a correct and proper risk assesment across a range of frequencies (63Hz to 8000Hz).
- Use the Attenuation Chart found in the User Instructions of hearing product alongside this frequency data to choose the correct ear defenders.
- The goal is to reduce noise exposure to below 80dB(A) at all measured frequencies.
