- Data presented as mean (± SD). Max, maximum values in dB of A-weighting on fast response time mode recorded by both devices during the study period; Min, minimum values in dB of A-weighting on fast response time mode recorded by both devices during the study period; LA 90, the A-weighted noise level that is exceeded for 90% of the measurement period (a useful descriptor to quantify the background noise level); LA50, the A-weighted noise level that is exceeded for 50% of the measurement period
- *Significant statistical difference
