Sound Transmission Testing  
ASTM E336

Pacific SBS provides expert acoustic sound transmission testing in general accordance with ASTM E336, a widely recognized standard for measuring airborne sound attenuation between rooms in both newly constructed and existing buildings. This testing is critical for ensuring that structures meet project-specific acoustic requirements and deliver the level of sound privacy and comfort expected by end-users. By evaluating how effectively walls, floors, and other assemblies prevent sound transmission, our testing services help architects, builders, and property owners verify compliance with design specifications, building codes, and occupant expectations, creating environments that enhance quality of life and functionality.

Our acoustic testing process involves the use of specialized equipment to measure sound transmission class (STC) ratings, which quantify the ability of a building assembly to reduce airborne sound transfer. Following ASTM E336 guidelines, Pacific SBS conducts field tests under controlled conditions, generating sound on one side of a partition and measuring its intensity on the other. This allows us to identify weaknesses in construction, such as gaps, poor sealing, or inadequate materials, that may compromise acoustic performance. For newly constructed buildings, our testing ensures that designs are executed correctly, while for existing structures, we help diagnose and address issues like excessive noise leakage that impact occupant satisfaction.

The benefits of acoustic sound transmission testing extend beyond compliance, contributing to occupant well-being and property value. At Pacific SBS, our experienced team delivers precise, reliable data to support architects and builders in optimizing acoustic performance. Whether it’s a residential complex, commercial office, or institutional facility, our testing ensures that spaces meet the acoustic standards required for their intended use, reducing noise complaints and enhancing user experience. By partnering with Pacific SBS for ASTM E336-compliant testing, clients can confidently create or maintain buildings that provide the sound isolation and comfort that end-users demand.
