Measurement microphones, despite their precision, inherently alter the sound field due to reflections and diffractions caused by their size and shape. This challenge becomes critical in car cabins, where non-ideal acoustic environments – defined by complex materials and confined spaces – compromise test reliability. Smaller microphones, optimized for such environments, offer solutions but also introduce new hurdles. Additionally, the growing use of microphone arrays to characterize automotive audio systems presents unique challenges. Join us as we delve into the intricacies of in-cabin acoustic measurements, explore cutting-edge solutions and address the evolving demands of automotive audio testing.
