M2 hourly Sound Pressure Levels 2019-2020
Quality
Root Mean Squared (RMS) Sound Pressure Levels (SPL) were calculated for the one-Third Octave Level (TOL) bands centered at 63 Hz, 125 Hz and 250 Hz; and for the broadband 50-1000 Hz using PAMGuide package (Merchant et al. 2015) and custom-made MATLAB code. One RMS SPL value per file was obtained, averaging 12 min of recording in M2.
Variables: time: datetime TOL63HZ: Sound Pressure Level for the third-octave level band centered at 63 Hz TOL125HZ: Sound Pressure Level for the third-octave level band centered at 125 Hz TOL250HZ: Sound Pressure Level for the third-octave level band centered at 250 Hz BB501000: Sound Pressure Level for the broadband 50-1000 Hz
