Does background noise affect the online test?
The online pure tone test should be taken in a relatively quiet room. A quiet room usually has noise levels below 45 dB. Noise levels above 55 dB depending can influence the results, more usually because you may be distracted by noise during the test and will take longer to get an accurate hearing threshold, but will not likely influence the test findings. The worst case is that background noise will cause a test result pattern to change from normal to conductive which means the findings will be classified as a medically treatable condition when none exists.
