Prediction models for mean level of memory disturbance after mitigation.
| Situation | Model form | Prediction model | R 2 |
|---|---|---|---|
| No fountain sound added | No | MLMD=0.065L SM−1.402 | 0.944 |
| With fountain sound added | Independent effects model | MLMD=0.042L SM+0.029L FS−1.679 | 0.887 |
| With fountain sound added | Energy summation model | MLMD=0.072L T−1.969 | 0.883 |
| With fountain sound added | Perceptual model | MLMD=0.552MSLL+1.012 | 0.809 |
| With fountain sound added | Perceptual model | MLMD=0.573MDcL+1.116 | 0.741 |
Notes. MLMD: Mean level of memory disturbance; LSM: Binaural LAeq of metro sound; LFS: Binaural LAeq of fountain sound; LT: Binaural LAeq of combined sound; MSLL: Mean subjective loudness level; MDcL: Mean discomfort level; R2: Coefficient of determination.
