Abstract
One embodiment provides a method comprising obtaining, via a microphone of a hearable device, one or more measurements of a first individual transfer function from a transducer of the hearable device to a first sound pressure at the microphone. At least a portion of the hearable device is within proximity of an ear canal of an individual ear. The method further comprises determining, based on the one or more measurements of the first individual transfer function, a second individual transfer function from the first sound pressure to a second sound pressure at an eardrum within the ear canal. The method further comprises applying, based in part on the second individual transfer function, personalized equalization (PEQ) within the audio full range (low, mid and high frequencies) to an audio signal for reproduction via the hearable device.
