A study by Spain’s Department of Thermal Engineering at the University of the Basque Country measured the sound absorption of living walls over a range of frequencies in an acoustic test chamber.

The study by Applied Acoustics concluded that :

  • Green walls provide a weighted sound reduction index of 15 db.
  • Green Walls gave a measure a sound absorption coefficient of 0.40.
  • Green wall have significant potential for sound insulation for vegetal architecture.
