Psychoacoustic indicators of pass-by road traffic noise

<p>This dataset contains files related to a measurement campaign of&nbsp;pass-by road traffic noise using the Statistical Pass-By (SPB) method&nbsp;according to ISO 11819-1 (2023) on road surfaces in hot mix asphalt.&nbsp;&nbsp;</p> <p>The compressed folder &quot;Audio files, timestamps and calibration file&quot; is divided into subfolders per measurement day, named according to the measurement date and location. Each subfolder contains&nbsp;continuous recordings as .wav audio files and Excel files with timestamps at 2 seconds before (t0) and 2 s after (tf) the moment a vehicle passage produced the peak noise level in that audio file, besides the air temperature (Tair) and vehicle category (Category). The pass-bys are classified into&nbsp;four categories (Passenger cars, Vans, Dual-axle heavy vehicle - HD and&nbsp;Multiple-axle heavy vehicle - HM).</p> <p>The file &quot;Calibration file 1Hz 113.7 dB.wav&quot; is a pure-tone 113.7 dB calibration file recorded from the sound level meter and microphone used in the measurements.</p> <p>The Excel file &quot;Psychoacoustic indicators of pass-by road traffic noise.xlsx&quot; presents&nbsp;nine acoustic and psychoacoustic indicators calculated from the 4s audio excerpts of&nbsp;2199 pass-by vehicle noise obtained from this measurement campaign. Calculations were conducted using the algorithms implemented on PsySound3.&nbsp;The columns in this Excel file mean the following:</p> <ol> <li>L_A,max:&nbsp;average maximum A-weighted sound level, in dB</li> <li>&Delta;L: the difference between the peak L_A,maxand the L_A,max at 2 s before the peak was reached, in dB</li> <li>L_A,eq:&nbsp;A-weighted equivalent continuous sound level, in dB</li> <li>L10:&nbsp;10% percentile statistical noise level, in dB</li> <li>L90:&nbsp;90% percentile statistical noise level, in dB</li> <li>N50: 50% percentile loudness, in sone</li> <li>S50:&nbsp;50% percentile sharpness, in acum</li> <li>R50:&nbsp;50% percentile roughness,&nbsp;in asper</li> <li>FS50:&nbsp;50% percentile fluctuation strength, in vacil</li> </ol>
