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 13):
The method of  claim 11 , wherein the adjusting of the internal sounds comprises:\n generating correction signals based in part on an inverse of the transfer function; and adjusting the first signals, based in part on the correction signals, to mitigate effects of the transfer function from the internal sounds.
