1. A hearing instrument, the hearing instrument comprising:
- a first electro-acoustic transducer;
a second electro-acoustic transducer having an acoustic output;
an ear tip having a first sound channel terminating at an orifice on a first end portion of the ear tip, the second electro-acoustic transducer disposed at least partially in the ear tip and the acoustic output of the second electro-acoustic transducer acoustically coupled to the first sound channel,the ear tip having a second sound channel that allows sound produced by the first electro-acoustic transducer to pass through the ear tip, the second sound channel compensating for occlusion that occurs when the ear tip is in use;
wherein the first electro-acoustic transducer compensates for sounds lost as a result of occlusion compensation.

Abstract
A hearing instrument includes a first speaker having a first frequency range. The hearing instrument also includes a second speaker that is disposed in the ear of a listener. The second speaker has a second frequency range that is wider than the first frequency range. A microphone unit is coupled to the first speaker and the second speaker. The first speaker creates replacement sounds within the first frequency range that replicate sounds that are lost to the listener as a result of an occlusion effect at the second speaker. The replacement sounds are presented to the listener.

10. A hearing instrument comprising:
-
a first electro-acoustic transducer; an ear tip having a first sound channel with a port at an inner end portion of the ear tip, at least a portion of the ear tip sized to fit in a user'"'"'s ear canal; a second electro-acoustic transducer, the second electro-acoustic transducer disposed at least partially in the ear tip in communication with the first sound channel; the ear tip including a second sound channel extending through the ear tip from an outer end portion of the ear tip to the inner end portion thereof, the outer end portion opposite the inner end portion, the first electro-acoustic transducer disposed proximate the outer end portion of the ear tip; an unsealed acoustic coupling between the first electro-acoustic transducer and the second sound channel; whereby sound from the first electro-acoustic transducer passes through the second sound channel from the outer end portion of the ear tip to the inner end portion of the ear tip. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
