India’s rapid growth brings community noise problems. One Acoustician in Bangalore offers some tips (alternate link) on reducing the noise:

The mistaken impression is that an acoustics expert is required only for special venues like cinemas, auditoria and studios. This is a myth. To realise the true potential of any built space the second sense of humankind - hearing - must be given its due importance.

..

Discotheques, pubs and nightclubs are sources of heavy doses of low-frequency soundwaves that are the most difficult to control. They have large wavelengths and need massive surfaces to control them.

..

The design community tends to confuse sound absorption and noise isolation. You require a porous material to absorb sound. Quite conversely, a porous material does not block noise.

..

Architects need to go back to the module on acoustics taught in architectural/civil courses or call in an acoustics expert.

This is good stuff. I might have to steal it.

(I’m kidding, please don’t sue me.)
