Abstract:
Various implementations include systems for providing enhanced aware mode capabilities in an ANR audio device. In particular implementations, a method includes receiving an ambient noise signal from a microphone associated with a wearable audio device; determining a gain value based on a sound pressure level (SPL) of the ambient noise signal; generating a gain adjusted ambient noise signal by applying the gain value to the ambient noise signal; generating a total external microphone signal by adding the gain adjusted ambient noise signal to a noise reducing ambient signal; generating an expanded audio signal by selectively adjusting a source audio signal based on the gain adjusted ambient noise signal; and combining and outputting the expanded audio signal with the total external microphone signal to an acoustic transducer.
