MEETING CURRENT APPROVED DOCUMENT E (2003) (ENGLAND & WALES) REQUIREMENTS
To achieve these requirements two options are available:
1. PRE-COMPLETION TESTING or
2. ROBUST DETAILS FOR WHICH NO PCT IS REQUIRED
For dwelling-houses, flats and rooms for residential
purposes, the site acoustic performance requirements are: |
|
Robust detail requirements, using laboratory testing
over specified structural floors, are: |

| GLOSSARY: |
| Rw = IMPROVEMENT IN AIRBORNE SOUND |
DnT,w = AIRBORNE SOUND INSULATION BETWEEN TWO ROOMS |
| Lw = IMPROVEMENT IN IMPACT SOUND |
L'nT,w = IMPACT SOUND INSULATION OF FLOORS |
| Ctr = LOW FREQUENCY CORRECTION FACTOR |
