Acoustic properties

Hard materials with a short reverberation time sound hard—while softer, more absorbent materials, such as wood, give a “warmer” sound. This is most noticeable in enclosed spaces such as streets, squares, and town gardens. Loose fastenings tend to rattle, and noise is one of the challenges of designing in towns. However, gardens and squares can provide a refuge from the sound of city streets (but not so much from aircraft noise).
