EN 15907 Interior Noise of Driver’s Cab Testing
The European Standard EN 15907:2014 sets forth requirements and methods to measure interior noise levels within the driver's cab of railway vehicles. This standard is crucial for ensuring passenger comfort, operator safety, and compliance with regulatory standards across the European Union and beyond.
Interior noise in a driver’s cab can significantly affect both the health and well-being of operators as well as the overall performance of the vehicle. The standard provides a framework to quantify the noise levels that may be encountered during normal operation, ensuring that these do not exceed specified limits set by national and international regulations.
Compliance with EN 15907 is mandatory for railway vehicle manufacturers aiming to sell their products within the European Economic Area (EEA). This requirement underscores the importance of accurate noise testing in the design and manufacturing process. By adhering to this standard, manufacturers can ensure that their vehicles meet stringent quality control measures and are free from excessive noise emissions.
Our laboratory offers comprehensive services tailored to meet these standards. Our team uses state-of-the-art equipment and follows rigorous protocols to provide accurate results. The testing process involves several critical steps including initial cab preparation, sound measurement, data analysis, and final reporting.
- Cab Preparation: Ensuring the interior of the driver’s cab is clean and free from any obstructions that could interfere with noise measurements.
- Noise Measurement: Using calibrated microphones to capture sound levels at various points within the cab during simulated operational conditions.
The results are then analyzed using statistical methods provided in EN 15907, allowing for accurate determination of compliance with specified limits. Our reports include detailed findings along with recommendations for improvements where necessary.
| Test Parameter | Description |

| Noise Levels | The maximum allowable noise levels within the driver’s cab as per EN 15907. |
| Measurement Points | Locations in the cab where sound level measurements are taken. |
| Data Analysis Methodology | The statistical techniques used to interpret the collected data against EN 15907 requirements. |
| Reporting Standards | The format and content of the final report, including recommendations for noise reduction strategies. |
Our expertise ensures that our clients receive reliable test results which are essential for maintaining high standards in the railway industry. Compliance with EN 15907 not only enhances safety but also contributes positively to the overall reputation of your organization by demonstrating a commitment to excellence.
Scope and Methodology
The scope of EN 15907 Interior Noise of Driver’s Cab Testing encompasses various aspects of interior noise within the driver's cab of railway vehicles. This includes both stationary and moving conditions, ensuring that all relevant factors are considered during testing.
- Stationary Conditions: Measurement in a static position to assess background noise levels without any operational disturbances.
- Moving Conditions: Testing while the vehicle is in motion to evaluate how noise behaves under real-world operating scenarios.
The methodology involves several key steps, each designed to provide accurate and reliable data. Firstly, the environment must be prepared according to EN 15907 guidelines to ensure consistent results. Secondly, sound level meters are placed at designated points around the cab. Thirdly, noise levels are recorded under both stationary and moving conditions. Finally, all collected data is analyzed using statistical methods provided in the standard.
This comprehensive approach guarantees that every aspect of interior noise within the driver’s cab is thoroughly examined. It also ensures that any discrepancies or areas requiring improvement can be identified early on, allowing for timely corrective actions to be taken.
International Acceptance and Recognition
- Eurobloc Compliance: EN 15907 is widely recognized across the European Union and other regions that adhere to EU standards. It ensures uniformity in noise testing procedures, facilitating easier trade between member states.
- Affirmation by ISO: While not directly a part of ISO, the principles and methodologies described in EN 15907 align closely with those recommended by international organizations like ISO for similar applications. This alignment fosters confidence among buyers worldwide who seek consistent quality assurance.
The standard's broad acceptance contributes significantly to its credibility within the industry. Companies adopting this practice not only meet regulatory requirements but also benefit from enhanced brand reputation and increased market share due to satisfied customers and stakeholders.
