Architecture characterized by hard surfaces and materials puts the good acoustics under pressure and can result in noise nuisances and poor speech intelligibility.
When it is difficult to lead a conversation or understand what is being said in a room, it can influence the well-being - whether at home, at work or in public spaces.
Acoustics regulation is an important factor when designing and building. Short reverberation times and good acoustics can with advantage be achieved with sound absorbing ceiling cladding.
