Setting your expected level of background noise affects which frequencies we recommend for testing. You can always override the recommendations.
For more information on test setup recommendations for different noise levels, see Test setup examples.

You have three choices of expected background noise level:
- Low background noise: For testing in environments such as a quiet room with a closed door, with expected noise levels of 0-40 dB SPL.
- Medium background noise: For testing in environments such as a doctor’s office, with expected noise levels of 40-60 dB SPL.
- High background noise: For testing in environments such as a trade show, with expected noise levels of 60-80 dB SPL.
