1. A hearing system comprising:
an ipsilateral microphone associated with an ipsilateral ear of a user and configured to detect an ipsilateral audio signal representative of audio content;
a contralateral microphone associated with a contralateral ear of the user and configured to detect a contralateral audio signal representative of the audio content; and
a hearing device associated with the ipsilateral ear and configured to:
determine a first sound pressure level (SPL) of a first spectral portion of the ipsilateral audio signal, the first spectral portion having frequencies included in a first frequency range;
determine a second SPL of a second spectral portion of the ipsilateral audio signal, the second spectral portion having frequencies included in a second frequency range that is higher than the first frequency range;
determine that the first SPL is greater than the second SPL by at least a threshold SPL amount;
determine that a symmetry level between the ipsilateral audio signal and the contralateral audio signal is at least a threshold symmetry level; and
determine, based on the determining that the first SPL is greater than the second SPL by at least the threshold SPL amount and the determining that the symmetry level is at least the threshold symmetry level, that the audio content comprises own voice content representative of a voice of the user.
