Today’s growing concern about the effect of sound on human performance is leading to increased regulation. Consequently, accurate acoustical performance measurement is critical for certification of building products and materials. Sound control on the interior of buildings is also becoming more of a factor in building design for office buildings, manufacturing facilities, and multi-family housing.
Acoustical performance of building products, components, and systems is an important consideration for engineers, architects, and building owners. This is especially true in highly populated cities; the demand for efficient noise reduction in building products in these areas is on the rise.
QAI uses recognized methods for testing:
Sound Absorption- Measures a material’s ability to control reflected sound and reduce noise levels, control reverberation, and improve listening environments. Sound absorption is measured either in a reverberation room acoustic chamber for large objects wall panels, fenestration products, insulation, foam, and/or building materials.
Sound Transmission (STC) – The measured reduction in noise level after sound passes through a material. This measure is used to rate the effectiveness of a material to attenuate sound. These measurements either alone or in combination used to rate fenestration products and materials for comparing or modifying to meet sound specifications or requirements.
Founded in 1995 by a group of experienced certification and testing experts, QAI is an independent third-party testing, inspection and certification organization which serves the building industry, government and individuals with cost effective solutions through our global, in-house capabilities / services.
