We spend 80 – 90% of our time indoors, making the quality of indoor environments crucial to our health and well-being. Building regulations specify minimum acoustic performance requirements for new dwellings, however these often fall short in ensuring an adequate living environment. Many residents still experience high levels of disruptive noise, especially in multi-dwelling buildings - for example hearing footfall from upstairs neighbours.

We spend 80 – 90 of our time indoors, making the quality of indoor environments crucial to our health and well-being. Many residents still experience high levels of disruptive noise, especially in multi-dwelling buildings. Therefore, there is growing recognition of the need for a more detailed acoustic classification system that addresses these shortcomings and promotes higher standards of acoustic comfort.
