Acoustics

Knauf Acoustic solutions not only improve the auditory experience but also contribute to a building’s overall performance by enhancing ambient comfort levels. This can lead to increased productivity and wellbeing for occupants, and meet standards required in various sectors.

Sound absorption controls sound reflections within a room, while sound attenuation controls sound transmission between rooms through a continuous suspended ceiling.

Sound absorption is measured using the sound absorption coefficient alpha (α). This value ranges from 0 (no absorption, total reflection) to 1.00 (total absorption).

Reverberation time is how long it takes for sound in a room to fade away. It's measured in seconds. Essentially, it's the time it takes for a sound to become very quiet.

Two things affect reverberation time: the size of the room, and the sound absorption qualities of the materials used in its construction. Our solutions can significantly change a room's reverberation time because they cover a large surface area and offer different levels of sound absorption. Choosing the right product can help achieve the desired reverberation time for a space.

Insulation products alone will not give a specific sound reduction value, only systems or construction elements will give this value. Therefore, any sound reduction numbers quoted will be in reference to a built system, e.g. partition wall or separating floor, not a slab or roll of insulation.
