Green design and smart technology for acoustic comfort

Buildings being made for people to live in and must take into account human comfort while being designed. As a matter of fact, comfortable indoor environments increase occupants’ productivity, health and overall well-being.

In a serie of four articles, we will look into different performance indicators, such as visual comfort, acoustic comfort, thermal comfort and air quality, that can be monitored in order to promote occupant's overall well being, health and performance in indoor spaces.

You can find our previous article about visual comfort here.

Today, half of the population lives in cities that are exhausted by noise-producing activities, equipments and transport. Meanwhile, our perception of sound is inherent to our capacity to interact with each other, communicate and our sense of space.

“ According to the World Health Organisation (WHO), noise-induced hearing impairment is the most prevalent irreversible occupational hazard and it is estimated that 120 million people worldwide have disabling hearing problems.”

So how can green design and smart technology improve acoustic comfort ?

The notion of acoustic comfort is subjective to the individual as well as on the quality and the intensity produced by the noise sources. This quality and the comfort of indoors have an influence on the quality of work, sleep and the relationships between people. When the acoustic comfort is poor, we can quickly observe negative effects such as decreased productivity, social conflicts and health issues.

There are three different types of noise sources in a building :

  • Airborne noise, sounds vehiculed by the air such as voices, music and transport.
