Marché des tests de bruit au passage – Taille, part, tendances de l’industrie et prévisions (2025-2032)

By Component:

Based on component, the pass-by noise testing market is segmented into hardware and software.

Trends in the component:

• The development of more compact and portable noise testing systems offers greater flexibility for on-site or less specialized testing environments.
• Consumers increasingly prioritize a quiet and comfortable driving experience, contributing to the perceived quality and luxury of a vehicle, that would further drive the pass-by noise testing market growth.
• Thus, based on the above analysis, these factors are driving the pass-by noise testing market demand and trends.

The hardware segment accounted for the largest revenue in the year 2024.

• These devices are extensively used in automotive, industrial, and environmental noise assessments. Technological enhancements have made sound level meters more accurate and easier to use, thereby driving their need.
• Vibration meters play a vital role in measuring and analyzing vibrations within machinery and equipment. These devices are crucial in predictive maintenance and condition monitoring across various industries. The increasing focus on minimizing machine downtime and enhancing operational efficiency has driven the adoption of vibration meters.
• For instance, m+p’s vibration control system offers precise closed-loop control of vibration test systems, primarily electrodynamic and hydraulic shakers. Their frequency ranges from 12.8 kHz to 40 kHz, depending on the measurement hardware.
• Thus, based on the above analysis, these factors are further driving the pass-by noise testing market growth and trends.

The software segment is anticipated to register the fastest CAGR growth during the forecast period.

• The software solutions are designed to handle the intricacies of various international standards (ISO 362, ECE R41, R51, R117, R138, US EPA, and others) and provide comprehensive insights.
• Software is increasingly integrating with CAE (computer-aided engineering) and simulation tools. This allows engineers to build virtual prototypes (digital twins) and predict pass-by noise levels early in the design cycle.
• Cloud-based platforms allow test data to be accessed and analyzed from anywhere, facilitating collaboration among geographically dispersed teams.
• Thus, the above factors are expected to drive the pass-by noise testing market share and trends during the forecast period.

By Testing Type:

Based on testing type, the pass-by noise testing market is segmented into indoor and outdoor.

Trends in the testing type:

• The shift from mechanical to electric powertrains fundamentally changes noise characteristics, necessitating new testing methodologies and research & development (R&D) efforts.
• The development of more accurate microphones, high-channel data acquisition systems, and sophisticated analysis software makes precise and efficient pass-by noise testing more feasible.
• Based on the above analysis, these factors are anticipated to further drive the pass-by noise testing market trends during the forecast period.

The outdoor segment accounted for the largest revenue in the year 2024 and it is expected to register the highest CAGR growth during the forecast period.

• The implementation and evolution of Additional Sound Emission Provisions (ASEP) and Real-Driving Additional Sound Emission Provisions (RD-ASEP) have significantly altered outdoor vehicle noise testing. This extends track time, increases the need for driver precision, and necessitates more sophisticated real-time feedback systems in the vehicle.
• With the shift to electric vehicles (EVs), engine noise is reduced, making tire-road noise the dominant source at typical urban speeds. Outdoor testing offers a unique advantage as it can accurately capture how a vehicle's sound emissions are affected by real road surfaces.
• Thus, the aforementioned factors would further supplement the pass-by noise testing market trends.

By End Use:

Based on end use, the pass-by noise testing market is segmented into automotive and transportation, aerospace and defense, power generation, consumer electronics, construction, industrial equipment, mining and metallurgy, and others.

Trends in the end use:

• Residential noise control systems are a vital part of creating peaceful homes. They provide solutions to reduce unwanted sounds from sources, such as neighbors, traffic, and even home appliances while improving comfort and residents' well-being.
• The continuous advancements in NVH testing technologies and the growing emphasis on innovation and research are driving the adoption of NVH testing devices in research institutes.
• Thus, the above factors are driving the global market.

The automotive and transportation segment accounted for the largest revenue share of 23.46% in the year 2024, and it is expected to register the highest CAGR growth during the forecast period.

• The automotive industry is the largest consumer of NVH testing devices, driven by the need to enhance vehicle comfort, performance, and compliance with stringent noise and vibration regulations.
• NVH testing is critical in the automotive industry for identifying and mitigating sources of noise and vibration in vehicles, thereby improving overall product quality and customer satisfaction.
• The continuous advancements in automotive technology, such as the development of electric and hybrid vehicles, have further amplified the need for sophisticated NVH testing solutions.
• Thus, the above factors and developments are driving the global market.
