EN 1793-3 Devices for Reducing Road Traffic Noise, Part 3: Normalized Traffic Noise Spectrum

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1793-3 testing. This part of EN 1793 gives a normalized traffic noise spectrum for evaluating the acoustic performance of devices designed to reduce traffic noise near roads.

EN 1793-3 Devices for Reducing Road Traffic Noise, Part 3: Normalized Traffic Noise Spectrum

Since the main acoustic characteristics of road traffic noise reduction devices, transmission loss and absorption are frequency dependent, a traffic noise spectrum needs to be defined for testing purposes. This standard defines the main characteristics of the measured traffic noise.

Defines the spectrum used for calculating the acoustic performance of traffic noise attenuating devices near roads in terms of odd-numbered ratings of sound absorption and airborne sound insulation.

This standard is not concerned with the determination of insertion loss (external performance), which is additionally dependent on factors unrelated to the product itself. The test is designed to allow measurement of the internal airborne sound insulation performance of the device; The resulting rating should aid in the selection of devices for resonant roadside applications.

EUROLAB assists manufacturers with EN 1793-3 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
