- Pass-by noise testing is a standardized method used to measure the external noise levels emitted by vehicles under specific conditions, ensuring compliance with regulatory thresholds set by bodies such as the UNECE and ISO
- The market is witnessing strong momentum due to growing environmental concerns, expanding vehicle fleets, and technological advancements in sensor systems, data acquisition, and edge AI analytics, which enable more accurate, real-time acoustic assessments across diverse vehicle types
- North America dominated the pass-by noise testing market with a share of 40.5% in 2024, due to stringent vehicle noise regulations and high investment in automotive testing infrastructure
- Middle East and Africa is expected to be the fastest growing region in the pass-by noise testing market during the forecast period due to gradual enforcement of noise regulations and the modernization of transportation infrastructure in the Gulf Cooperation Council (GCC) region
- Hardware segment dominated the market with a market share of 58.8% in 2024, due to the high demand for precise sound measurement equipment such as microphones, sound level meters, accelerometers, and data acquisition systems. Automotive and aerospace manufacturers rely heavily on robust hardware setups for in-field and laboratory noise testing, ensuring compliance with regulatory noise emission standards. The rising stringency of pass-by noise regulations across various regions is further reinforcing the need for advanced hardware solutions that can deliver real-time, high-fidelity acoustic data during vehicle testing
