The latest episode of The InEVitable features Rishi Daftuar, chief engineer of JBL Automotive, for an in-depth discussion about in-car sound quality, the evolution of automotive audio systems, and how quieter electric vehicles are changing the listening experience.
Inside the World of Automotive Audio Engineering
The episode introduces Daftuar through Toyota and JBL’s 30-year partnership in automotive audio, previously covered by Zach Gale.
Daftuar discusses his passion for audio engineering and explains how his interest in sound quality led him to study electrical and sound engineering at the University of Michigan. He also reflects on his professional journey before joining JBL, including time working as a sound engineer for the rock band IAMDYNAMITE.
How Electric Vehicles Are Changing Car Audio
A major focus of the conversation centers on the changing role of in-car audio systems, particularly as electric vehicles become more common.
Daftuar explains how JBL collaborates with its automotive manufacturing partners, especially Toyota, to develop audio systems designed for modern vehicles. The discussion highlights how quieter EV cabins have influenced audio engineering and the overall in-car listening experience.
Maintaining Consistent Audio Quality
The episode also examines how manufacturers maintain consistent sound quality across hundreds of thousands of vehicles produced on assembly lines.
Daftuar explains how JBL tests and validates audio performance to ensure customers receive the same listening experience from vehicle to vehicle.
As part of the discussion, he shares several artists whose music is used during audio testing, including Meghan Trainor, John Legend, Steely Dan, Queens of the Stone Age, and My Bloody Valentine. He also reveals his personal favorite song for evaluating audio systems.
The Impact of Software-Defined Vehicles
The conversation extends beyond speakers and sound tuning to broader developments in the automotive industry.
Topics include software-defined vehicles (SDVs), centralized computing systems, zonal architecture, and emerging 48-volt electrical systems, along with how these technologies influence vehicle audio systems.
Tips for Better In-Car Sound
The episode concludes with practical advice for drivers and audio enthusiasts looking to improve their in-car listening experience, whether using a factory-installed audio system or a premium setup.
The full conversation is available to watch on YouTube or listen to as a podcast through supported podcast platforms, offering an inside look at the engineering behind modern automotive sound systems.
