- Abstract
This review presents airborne noise test results collected over the last eight years during the Auckland apartment boom and aims to improve the industry's information base when considering the difference between walls of known laboratory performance and the measured field performance for the same nominal wall construction. Statistical analysis of the field results collected for various drywall constructions is presented in STC, R'w and DnT, w criteria with subsequent guidance when establishing and negotiating suitable on-site project criterion for multi-level construction contracts. Probabilities of achievement of various ratings are provided based on four projects using three wall types. Given the desire within the New Zealand industry to offer an upgrade on the existing site rating of FSTC 50, the authors suggest an R'w rating in the low 50 dB range is appropriate and achievable.
