1. A method comprising:
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.
