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 2):
The listening device of  claim 1 , wherein the controller is configured to compute the transfer function by executing steps to:\n perform spectral estimation on the first signals and the second signals to generate a frequency distribution; and compute the transfer function based in part on the frequency distribution.
