Auto makers carefully engineer the sounds of cars to create a specific driving experience, including the thunk of a door to make the car feel more solid and well-built.
Automakers use synthetic sound generation technology to shape and amplify engine sounds, considering factors like noise, vibration, and harshness (NVH) to match the engine sound with the vehicle's performance level.

The Importance of Sound in Cars
The sound of a car is carefully engineered to create a specific driving experience. Every sound, even the sound of the door closing, is designed to meet consumer expectations and communicate the quality of the vehicle. The thunk of a door, for instance, can make a car feel more solid and well-built. Car enthusiasts also value the raw sound of the engine and may prefer to listen to the motor while driving. As cars become better insulated, auto makers have started electronically editing and amplifying engine sounds to enhance the driving experience.
Factors Considered in Designing Car Sounds
When designing the sounds of a car, auto makers consider the type of car and the expectations of its intended audience. Luxury cars often have refined and low-volume sounds, while sports cars have rougher, more characterful sounds at higher volumes. Factors such as noise, vibration, and harshness (NVH) are taken into account to match the engine sound with the vehicle's performance level. Auto makers use synthetic sound generation technology to shape and amplify engine sounds, ensuring consistent outputs across different models and model years.
The Future of Car Sounds
As hybrid and electric cars gain popularity, the engine sounds of vehicles are changing. Electric motors produce quieter sounds, leading to questions about safety and public awareness. Will artificial sound enhancements become necessary for quiet vehicles? Additionally, future generations may associate performance and power with electric motors, shifting the definition of what constitutes a powerful and desirable car sound.
Some car sounds are more obvious like the horn or engine... but what about the not-obvious-until-you-point-them-out sounds like the hollow thud of a trunk or the click of a latch? The sounds a car makes are so closely associated with quality, so how, exactly, do car makers handle this aspect of the driving experience?
