One could include the Harmonica indicator in a futur noisemap.

The Harmonica indicator needs the mid term L10 and L90. I think we will not be able to have this indicators until previous works on temporal interpolation and spatial classification.

Maybe other simpler perceptual indicators could be used with more confidence, such as a simple linear relationship between the noise level L50 or Leq and an estimated pleasantness score between 0 and 10 for example.
