How Porsche Creates The Perfect Sounds

In the automotive world, the allure of a Porsche extends beyond its sleek design and powerful performance; it also lies in its distinctive sound. At Porsche's Zuffenhausen facility, a team of acoustic engineers led by David Sadowski works meticulously to fine-tune every auditory detail, ensuring that each vehicle not only performs impeccably but sounds perfect. One of their most innovative tools is an artificial head named Sam, which plays a crucial role in this intricate process.
Crafting the Signature Porsche Sound
Every Porsche is designed to deliver a sensory experience, and sound is a critical component. Whether it's the reassuring thud of a door, the robust purr of the engine, or the subtle sweep of windshield wipers, each sound contributes to the overall driving experience. However, ensuring these sounds harmonize beautifully requires precision and innovation.
David Sadowski, an acoustic engineer at Porsche since 2015, leads the charge in acoustic quality analysis. His journey began at Porsche's Weissach development site, where he honed his skills in the pre-series stages of vehicle design, focusing on how sound contributes to the brand's legendary driving experience.
Sam: The Artificial Acoustician
One of the stars of Sadowski's team is Sam, an artificial head equipped with a binaural measurement system. This system features two ears complete with ICP® microphones, enabling Sam to record sounds across a dynamic range of 130 dB. Sam's design mimics the human auditory system, providing a natural listening impression crucial for evaluating the car's acoustics accurately.
Using Sam, the team can assess how different sounds are experienced within the vehicle's cabin. This is vital not only for traditional combustion engines but increasingly so for electric models like the Porsche Taycan. In electric vehicles, where typical engine noise is absent, even minor sounds like an oil pump can become prominent, requiring careful adjustment to maintain the brand's characteristic sound.
Beyond Engine Noise: A Holistic Approach
Sadowski's team extends their scrutiny beyond engine sounds to include user-controlled noises such as door closing and the audio system's sound quality. They ensure that all frequencies are equally audible across different seating positions, enhancing the auditory experience for all passengers.
Each detail, from the click of a button to the background hum of the motor, is evaluated and fine-tuned. In electric vehicles, where the engine does not naturally produce the traditional Porsche sound, the team creatively enhances certain sounds to emulate this iconic auditory signature.
On the Road with Sam
Sam is not confined to the lab; he travels thousands of kilometers in test vehicles to gather real-world data. This extensive testing helps identify any discrepancies in the sound landscape, which might indicate underlying mechanical issues. By correlating sound data with vibration measurements, the team can pinpoint and resolve unwanted noises, ensuring that the vehicle not only runs smoothly but also sounds flawless.
The Sound of Quality
For Porsche, the sound of a vehicle is as much a hallmark of quality as its speed or handling. Sadowski's team, with Sam's indispensable assistance, plays a pivotal role in crafting this experience. Their work ensures that every Porsche not only drives like a dream but also sounds like one, reinforcing the luxurious and performance-centric identity of the brand.
Through their meticulous attention to auditory detail, Porsche continues to define what luxury sounds like, one vehicle at a time. Whether cruising down a country road or navigating city streets, drivers of these vehicles can expect nothing less than acoustic perfection, thanks to the innovative efforts of acoustic engineers like David Sadowski and his artificial colleague, Sam.
