Noise Emission Testing​

Supporting a Quieter, Safer Environment Through Comprehensive Acoustic Testing

DEKRA's noise emission testing services ensure that outdoor machinery manufacturers and operators comply with all legal noise limits, contributing to a quieter environment while meeting regulatory requirements across global markets.

About Noise Emission Testing​

At DEKRA, we prioritize safety, security, and sustainability in all areas of life—on the road, at work, and at home. We are committed to reducing harmful noise emissions that affect our well-being. ​
Noise pollution is a significant environmental challenge, stemming from heavy machinery, construction sites, and road traffic, leading to health issues and community disruption. For manufacturers and operators of outdoor machinery, complying with legal noise limits is necessary for regulatory compliance and a significant step towards a quieter, healthier, and more sustainable future.
To help you meet your compliance and quality objectives, DEKRA offers internationally accredited acoustic testing services tailored for outdoor machinery and equipment. We operate under key directives, including the Outdoor Noise Directive 2000/14/EC and the Machinery Directive 2006/42/EC. Our comprehensive testing approach ensures that your products meet regulatory requirements and contribute to a more sustainable acoustic environment.​
Our services include precise sound power level measurements in real or simulated outdoor conditions, CE compliance testing for market access within the EU and globally, noise emission assessments for electrical and non-electrical machinery, and calibration and verification of acoustic testing instruments. We offer flexible testing options at our accredited laboratories in Germany and China or directly at your site, providing minimal disruption to your operations.
