Psychoacoustic indicators of pass-by road traffic noise

This dataset contains nine acoustic and psychoacoustic indicators calculated from 4s audio excerpts of 2199 pass-by vehicle noise of four categories (Passenger cars, Vans, Dual-axle heavy vehicle - HD and Multiple-axle heavy vehicle - HM), besides the air temperatures and speed registered during each passage. The calculations were conducted using the algorithms implemented on PsySound3. These records were obtained by following the Statistical Pass-By (SPB) method as per ISO 11819-1 (2023) on road surfaces in dense asphalt concrete.  

1. L_A,max: average maximum A-weighted sound level, in dB
2. ΔL: the difference between the peak L_A,max and the L_A,max at 2 s before the peak was reached, in dB
3. L_A,eq: A-weighted equivalent continuous sound level, in dB
4. L10: 10% percentile statistical noise level, in dB
5. L90: 90% percentile statistical noise level, in dB
6. N50: 50% percentile loudness, in sone
7. S50: 50% percentile sharpness, in acum
8. R50: 50% percentile roughness, in asper
9. FS50: 50% percentile fluctuation strength, in vacil
