ASTM E90 Laboratory Sound Transmission Loss Testing
The ASTM E90 Standard Test Method is a critical component in assessing sound insulation properties of building materials and assemblies. This method evaluates the ability of a material or assembly to reduce the amount of airborne sound that passes through it, quantified as sound transmission loss (STL). STL testing is essential for ensuring compliance with various international standards such as ISO 140-4 and ASHRAE 53.
The ASTM E90 procedure involves placing a test specimen between two chambers within a controlled environment. One chamber, the receiving room, is exposed to sound from an external source while the other, the source chamber, contains the noise generator. The specimens are typically made of materials used in construction, such as walls, partitions, and doors.
The testing setup consists of a three-room configuration: two test chambers separated by the specimen under test and a third room that serves as an ambient reference point. The sound field is generated using a random incidence noise source, which ensures uniformity across the entire surface area of the specimen being tested. This setup allows for precise measurement of STL over specific frequency ranges.
The primary goal of ASTM E90 testing is to determine how effectively materials and assemblies block sound transmission from one room to another. The results provide critical insights into the acoustic performance of building elements, helping architects, engineers, and construction professionals design spaces that meet stringent noise control requirements. By employing this standard test method, organizations can ensure their products are compliant with relevant regulations while also enhancing user comfort by minimizing unwanted noise penetration.
Key aspects of ASTM E90 include:
- The use of a three-room setup for accurate STL measurement
- A random incidence noise source to simulate real-world conditions
- Detailed frequency analysis for comprehensive data interpretation
- Compliance with international standards such as ISO 140-4 and ASHRAE 53
This testing is particularly important in sectors like residential construction, commercial buildings, healthcare facilities, and educational institutions where soundproofing is crucial. By leveraging ASTM E90, businesses can significantly improve the acoustical performance of their products, thereby enhancing customer satisfaction and operational efficiency.
