Abstract: Methods and apparatus relating to functional safety critical audio system for autonomous and industrial applications are described. In an embodiment, safety island logic circuitry transmits an enable signal to cause initiation of a functional safety test for an audio component in a vehicle. Audio processing logic circuitry receives the enable signal and causes activation of power amplifier logic circuitry, in response to the enable signal, to drive the audio component in accordance with an audio alert test signal. The audio component includes a Parametric Acoustic Array (PAA) transducer. Other embodiments are also disclosed and claimed.
