| E3 REVERBERATION IN COMMON AREAS |
|
The Approved Document E 2003 Edition – Resistance to the passage of sound, introduced standards for reverberation in flats and rooms for residential purposes. By adopting the Rockfon ceiling or wall absorption solutions you can meet the required ADE standards for reverberation. No pre-completion site testing required.
Rooms with many hard surfaces may result in disturbing ‘echo’ which must be avoided. A reverberation time below 0.6 seconds is desirable, even in a quiet environment.
For all of your reverberation projects, browse the solutions below or simply select the solution you need on Rockfon website that will enable you to comply with Approved Document B, Part E3. You can also download in PDF E3 section of SoundPro brochure.
Rockfon ADE Part E3 sound absorption solutions can be grouped into the following categories:
1. Suspended acoustic ceilings with Classes C, B and A sound absorption (available in a wide variety of finishes, sizes and edge details)
2. Bonded acoustic ceilings with Class C sound absorption
3. Direct fix acoustic ceilings with Class C sound absorption (with no or minimal airspace behind)
4. Seamless acoustic ceilings with Class B sound absorption
5. Acoustic wall absorption solutions with Class B and better sound absorption. |
