Abstract:
A listening device includes a reference microphone positioned outside a blocked ear canal of a user to receive environmental sounds and generate first signals based on the environmental sounds. A loudspeaker is coupled to the reference microphone and positioned inside the ear canal to generate internal sounds based on the first signals. An internal microphone is positioned inside the ear canal to receive the internal sounds from the loudspeaker and generate second signals based on the internal sounds. A controller is coupled to the internal microphone and the reference microphone to compute a transfer function based on the first signals and the second signals. The transfer function describes a variation between the environmental sounds and the internal sounds caused by the listening device blocking the ear canal. The controller adjusts, based on the transfer function, the internal sounds to mitigate the variation.

Claim (Index 7):
The listening device of  claim 1 , further comprising a second internal microphone positioned inside the ear canal of the user and configured to receive the internal sounds from the loudspeaker, wherein the listening device is configured to determine a first acoustic pressure of the environmental sounds received by the reference microphone and a second acoustic pressure of the internal sounds received by the second internal microphone.
