Porsche’s Perfect SOUND Development

Discover how Porsche engineers analyze and adjust the sound design of their vehicles — with the help of an artificial head called Sam. One of his most important tools: the artificial head. The artificial head is a so-called sound acoustic module, and his human colleagues affectionately call him ‘Sam’ for short. Sam has all the acoustically relevant components of an upper body and an outer ear. This guarantees a natural listening impression, which provides the best conditions for evaluating product sounds. Incorporated into him is a binaural measurement system, meaning he has two ears with two ICP® microphones. These microphones have their own preamplifiers and can record in a dynamic range of 130 dB, meaning they can capture especially loud or quiet tones with consistent quality. Source : Porsche #porsche
