ASTM E90 Laboratory Measurement of Airborne Sound Insulation
The ASTM E90 standard method is widely recognized in the construction and acoustics sectors as a critical tool for evaluating the sound insulation performance of various building materials. This laboratory-based test assesses how effectively different materials, such as partitions, floors, or doors, block airborne sound transmission. The primary goal is to ensure compliance with regulatory requirements while also enhancing the acoustic comfort within buildings.
The ASTM E90 procedure involves placing a specimen between two spaces in which controlled noise levels are established. One space acts as the source of noise, typically using a broadband white noise generator, while the receiving room remains quiet. The sound pressure level difference is measured across the specimen under test conditions to determine its airborne sound insulation performance.
The accuracy and reliability of ASTM E90 depend significantly on several factors including the correct preparation of specimens, precise instrumentation, and appropriate environmental controls within the laboratory. Specimens must be cut with precision to standard dimensions ensuring that only the intended material is tested. The test setup includes specialized chambers designed to minimize reflections and ensure accurate measurement.
The acceptance criteria for ASTM E90 are based on the sound reduction index (SRI), which quantifies the effectiveness of a partition in reducing noise transmission from one room to another. The SRI value is derived by comparing the actual transmitted noise level with a reference value determined by the thickness and type of material used.
Understanding the significance of ASTM E90 extends beyond mere compliance; it plays a crucial role in improving the overall sound environment within buildings, contributing to healthier living spaces and more productive working environments. In sectors like healthcare, education, or residential construction, ensuring high levels of airborne sound insulation is essential for maintaining privacy and reducing noise pollution.
Accurate measurement according to ASTM E90 not only meets regulatory standards but also supports the development of innovative materials that can enhance acoustic performance further. By adhering strictly to this protocol, laboratories can provide reliable data that informs design decisions and contributes to a better understanding of material behavior under specific acoustic conditions.
The process involves several key steps from sample preparation through final analysis:
- Specimen preparation ensuring correct dimensions
- Setting up the test chamber with appropriate controls
- Generating controlled noise in one space while keeping another silent
- Measuring sound pressure levels across the specimen
- Analyzing results to calculate SRI
This method ensures that any discrepancies or anomalies are captured early, allowing for adjustments before final testing. The precision of ASTM E90 makes it an indispensable tool in both research and commercial applications.
With increasing focus on sustainable architecture and green building practices, the importance of effective sound insulation cannot be overstated. Proper implementation of ASTM E90 helps architects and engineers design spaces that not only meet regulatory requirements but also enhance user experience by creating quieter, more comfortable environments.

Quality and Reliability Assurance
The quality and reliability of acoustic tests conducted per ASTM E90 are paramount for ensuring accurate results that can be trusted by architects, engineers, and building owners alike. At Eurolab, we employ rigorous quality assurance measures throughout the testing process to maintain high standards.
Firstly, our laboratories are equipped with precision instruments calibrated according to international guidelines such as ISO 9614-2 for sound level meters. This ensures that all measurements are accurate and consistent across multiple tests. Secondly, our staff undergo continuous training to stay updated on the latest techniques and best practices in acoustics testing.
Every test begins with meticulous specimen preparation following ASTM E90 specifications. Specimens must be cut precisely to ensure only the intended material is tested, which is crucial for accurate results. Once prepared, specimens are carefully placed into specially designed chambers that minimize reflections, further enhancing measurement accuracy.
The testing procedure itself follows strict protocols outlined in ASTM E90. Controlled noise is generated in one chamber while another remains silent, allowing precise measurements of sound pressure levels across the specimen. These readings are then used to calculate the SRI value, which determines the effectiveness of the material at blocking airborne sound.
Data collected during the test undergoes thorough scrutiny by our experienced analysts who ensure that all results comply with ASTM E90 criteria before finalizing reports. This comprehensive approach guarantees that clients receive reliable and actionable insights from their acoustic tests.
Our commitment to quality does not end here; we also maintain robust records of all testing activities, including calibration certificates for instruments and documentation of specimen preparation procedures. These records are available upon request and serve as additional assurance of our adherence to best practices in acoustics testing.
