EN 14351 Acoustic Performance Testing of Automotive Glass Materials
The European Standard EN 14351 defines the requirements and methods for measuring acoustic performance of automotive glass materials. This standard ensures that the glass used in vehicles meets stringent sound insulation criteria, which is critical for maintaining a comfortable interior environment and reducing noise pollution.
Automotive glass plays a pivotal role in the overall design and functionality of vehicles. It not only provides structural integrity but also contributes to sound management within the cabin. The acoustic performance testing specified by EN 14351 aims to quantify how effectively the glass blocks unwanted sounds, such as road noise, engine noise, and external noises like wind or traffic.
The standard is particularly important for electric vehicles (EVs) where the absence of traditional engine sounds necessitates advanced sound management strategies. By adhering to EN 14351, manufacturers can ensure that their glass products contribute effectively to a quieter cabin experience, which is increasingly valued by consumers.
Testing acoustic performance involves measuring the transmission loss of sound through the glass under various conditions. This includes frequency-specific measurements at different sound pressure levels and durations. The testing setup typically consists of anechoic chambers equipped with appropriate sensors and transducers capable of capturing precise acoustic data.
The methodology for this test is standardized to ensure consistency across laboratories. Specimen preparation involves cutting glass samples to specific dimensions, which are then mounted in a controlled environment to simulate real-world vehicle conditions. The testing apparatus includes sound sources that generate known sound pressures, and receivers positioned on the opposite side of the glass sample to measure transmitted sound.
Acceptance criteria for passing this test are based on specified transmission loss values at various frequencies. Compliance with these standards ensures that the glass used in vehicles meets the necessary acoustic performance requirements set forth by EN 14351. This not only enhances passenger comfort but also contributes to the overall environmental and regulatory compliance of automotive manufacturers.
Our laboratory uses state-of-the-art equipment and adheres strictly to the procedures outlined in EN 14351, ensuring accurate and reliable results. By partnering with Eurolab for acoustic performance testing, you can be assured that your glass materials will undergo rigorous evaluation to meet international standards.

Scope and Methodology
The scope of EN 14351 encompasses various aspects of acoustic performance testing for automotive glass. The standard specifies the requirements for measuring transmission loss at specified frequencies across different sound pressure levels. It also outlines the methodology for preparing specimens, conducting tests, and evaluating results.
Specimen preparation involves cutting glass samples to specific dimensions that are representative of real-world applications in vehicles. These specimens are then mounted in a controlled environment to simulate the conditions they will encounter during use. The testing apparatus includes sound sources capable of generating known sound pressures at various frequencies, along with receivers positioned on the opposite side of the glass sample.
The test setup is designed to minimize external noise interference and ensure accurate measurement of transmitted sound. Testing parameters include frequency-specific measurements over a range of sound pressure levels and durations. The results are recorded using high-precision instruments and analyzed according to predefined criteria outlined in EN 14351.
Acceptance criteria for passing this test are based on specified transmission loss values at various frequencies. Compliance with these standards ensures that the glass used in vehicles meets the necessary acoustic performance requirements set forth by EN 14351. This not only enhances passenger comfort but also contributes to the overall environmental and regulatory compliance of automotive manufacturers.
