Table 1 Descriptive statistics for overall and festival-specified LAeqcomp, LCeq, LZeq, 63Hz, along with the corresponding counts exceeding WHO- and Belgian guidelines. Data are presented for both compensated (comp) and non-compensated (non-comp) levels, accounting for the use or non-use of hearing protection devices.
From: Large-scale music events can cause subclinical hearing damage
