EN 1793 Road Vehicle Interior Acoustic BSR Test
The EN 1793 Road Vehicle Interior Acoustic BSR (Buzz, Squeak & Rattle) test is a critical procedure aimed at ensuring the acoustic integrity and comfort of vehicle interiors. This test evaluates the sources of unwanted noises that can affect passenger satisfaction and drive the need for improvements in automotive design. The primary goal is to identify any potential issues such as buzzes, squeaks, rattles, or other sounds that could arise during the operation of a road vehicle.
The EN 1793 test method specifies the procedures and criteria required to assess the acoustics inside passenger cars, light commercial vehicles, motorcycles, and mopeds. It is an important step in ensuring compliance with European Union regulations on noise emissions from motor vehicles. This testing ensures that automotive components contribute positively to a quiet and comfortable driving experience.
The test involves the following key steps:
- Preparation of specimens
- Installation of microphones for sound measurement
- Conducting road tests under specified conditions
- Data analysis using specific acoustic instruments
- Evaluation against prescribed criteria to determine compliance with EN 1793 requirements
The scope and methodology of the test are designed to identify sources of noise that might affect vehicle performance. By adhering strictly to this standard, manufacturers can ensure their vehicles meet stringent acoustics standards set by regulatory bodies.
Scope and Methodology
| Aspect | Description |
|---|---|
| Test Specimens | The EN 1793 test applies to all road vehicles, including passenger cars, light commercial vehicles, motorcycles, and mopeds. Each specimen must be prepared according to the specified guidelines for the test. |
| Measurement Criteria | Data is collected using microphones placed at specific locations within the vehicle. Sound levels are measured in decibels (dB) under controlled road conditions. |
| Test Conditions | The tests are conducted on standard roads with varying speeds and terrains to simulate real-world driving scenarios. |
| Data Analysis | Acoustic data is analyzed using advanced instrumentation to identify any sources of noise that exceed acceptable limits as defined by EN 1793. |
The methodology ensures a comprehensive evaluation of the vehicle interior's acoustic environment, identifying areas where improvements are necessary. By adhering strictly to these procedures, manufacturers can ensure their vehicles meet the highest standards for passenger comfort and safety.
