Data measured by NoiseCapture app [6]. Minimum (Min), maximum (Max), mean (Mean) values of fast sound level, percentile noise levels in dB(A) over the whole measurement duration: LA90, A-weighted noise level that is exceeded for 90% of the measurement period; LA50, A-weighted noise level that is exceeded for 50% of the measurement period; LA10, A-weighted noise level that is exceeded for 10% of the measurement period; repartition of the noise exposure (RNE), used for percentile categorization of noise distribution over the whole recording period into 5 groups: group 1, ˂ 45 dB(A); group 2, 45–55 dB(A); group 3, 55–65 dB(A); group 4, 65–75 dB(A); and group 5, ˃ 75 dB(A)
