By Component, testing equipment dominated the market, while noise measurement software fastest-growing segment.

The testing equipment segment had the share of revenue at 42.00% in 2025. This is because companies need to measure noise accurately to meet the rules for vehicle noise. Automotive manufacturers and testing facilities are spending money on equipment like microphones and data systems to make sure their products are good and meet the rules. They want to be sure that their vehicles are quiet enough. Testing Equipment is used for passenger vehicles, commercial vehicles and electric vehicles. From 2025 to 2026 HBK made its Testing Equipment better. Now it can measure noise of vehicles automatically and check the noise of vehicles digitally.

The noise measurement software segment is going to grow fast at 7.08% per year. Automotive manufacturers are using software that can do a lot of things automatically like check the noise of vehicles and make reports. This software uses intelligence to help engineers. It can even make copies of vehicles and check if they meet the noise rules. This makes it easier for engineers to test vehicles and make them quieter. As more vehicles become electric it is getting harder to check the noise of vehicles. With this software it is becoming easier to find the sources of noise like the tires or the wind.

By Vehicle Type, passenger vehicles dominated the market, while electric vehicles are the fastest-growing segment.

The passenger vehicles segment had the part of the market with 46.00% in 2025. This is because many passenger cars are being made all over the world and the rules for vehicle certification are getting stricter in all the major automotive markets. The companies that make vehicles are spending a lot of money to make sure the noise outside the vehicle is as low as possible when they are developing vehicles. They want to follow the rules set by UNECE and other regional groups. They also want to make their customers more comfortable and make the vehicles overall. New passenger vehicle models are being introduced quickly and old models are being updated all the time.

The electric vehicles segment is expected to grow the fastest with a rate of 9.40% during the time we are looking at. Electric vehicles are very quiet when they move so the people who design them are now focusing on the noise made by the tires on the road the noise made by the air moving around the vehicle and the noise made by systems in the vehicle. This means they need advanced ways to test the noise of vehicles as they drive by. The people in charge of making the rules are still working on how to test vehicles.

By Application, vehicle certification dominated the market, while regulatory compliance is the fastest-growing segment.

The vehicle certification segment had the share of revenue at 39.00% in 2025. This is because every new Vehicle Certification needs to be approved before it can be sold in the market. Automotive companies need to do noise tests to show that they meet the rules. They have to do these tests to sell their vehicles in countries. More and more vehicles are being exported to countries and the rules for certification are changing. So companies are investing in testing facilities and equipment to measure noise accurately.

The regulatory compliance segment is going to grow fast at a rate of 6.30%. Governments over the world are making new rules to reduce noise pollution from traffic. They want to make cities cleaner and quieter. Because of these rules Vehicle Certification companies have to do more tests to make sure they are following the rules. They also have to update their testing equipment to meet the international standards. There are digital platforms that help companies manage these rules and test reports. This makes it easier for them to follow the rules. In 2025 and 2026 the rules for vehicle noise were.

Market Dynamics:            

Growth Drivers: Increasing stringency of global vehicle noise regulations driving demand for advanced testing.

The main thing that is helping the pass-by noise testing market to grow is that the rules about vehicle noise are getting stricter over the world. The people in charge of these rules are making them tougher to reduce the noise that vehicles make and to make the roads safer. So the companies that make vehicles are spending a lot of money on equipment that can measure noise well on systems that can test vehicles automatically on software that can process signals digitally and on platforms that use artificial intelligence to analyze noise and vibration. This is because they want to make sure their vehicles meet all the rules and can be sold quickly.

In 2025 HBK was still growing its business in the sector by adding new systems for measuring pass-by noise and new digital solutions for analyzing noise and vibration. These new systems and solutions are helping vehicle manufacturers, over the world to meet the rules and sell their vehicles.

Restraints: High capital investment and complex testing infrastructure requirements.

The big problem with this is that it costs a lot of money to set up a place to test the noise that cars make when they drive by. The rules say that these places have to be very good at testing the noise so they need good microphones and other equipment to measure the sound. They also need tracks to test the cars on and equipment to check the weather. They need special software to make sure everything is okay. In April 2026 some big companies that test cars decided to spend money on special equipment to make testing easier and cheaper in the long run.

Opportunities: Electric vehicle expansion creating new demand for precision acoustic validation.

The chance to get into the electric vehicle market is creating a need for precise acoustic validation. The world is moving towards cars really fast and this is a big opportunity for the pass-by noise testing market in the long run. Electric vehicles are very quiet because they do not make much noise as regular cars so when we test them for noise outside we have to pay attention to the noise the tires make on the road the air moving around the car and other systems like the warning sounds. Companies are putting money into engineering, testing that happens virtually and special computers that can predict what the noise will be like.

In 2025 Siemens Digital Industries Software kept making its Simcenter program better by adding features to help with noise and acoustic engineering, for electric vehicles, which will help with development and making sure they follow the rules.
