Acoustical Testing

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.

Typical Products Tested

• Windows
• Doors
• Skylights
• Tiles

Frequent Standards we test against:

• ASTM E90 – Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements
• AAMA 1801 – Sound Transmission Loss Measurement Procedure for Windows, Doors, Skylights and Glazed Wall Sections
