Embodiments provide for improved determination of whether an audio protector is sufficiently fit to a wearer. By automatically performing the improved fit testing processes described, embodiments may warn users in circumstances where fit of their audio protector is dissatisfactory. Some embodiments include receiving external audio data and internal audio data including a filtered range of frequencies, generating comparative internal data by applying the internal audio data to an inverse attenuation model, identifying an audio processing mode based at least in part on the external audio data and/or the internal audio data, the audio processing mode associated with an audio comparison model, computing energy differential data by applying the comparative internal data and the external audio data to the audio comparison model; and determining a fit result based at least in part on the energy differential data.
