## Summary

Hosts Daniel and Forbode discuss how active noise cancellation (ANC) technology, traditionally found in headphones like AirPods Pro, is being adapted for electric and autonomous vehicles to reduce road and wind noise. They explain the engineering challenges of achieving perfect destructive interference in a complex cabin environment, including timing, coverage, and safety constraints. The conversation highlights how software-defined vehicles use algorithms to create a 'quiet bubble' around passengers, allowing manufacturers to reduce the physical mass of sound-deadening foams, thereby improving EV range and efficiency.
