Dual microphone EAS system that prevents feedback
First Claim
1. A method comprising:
- processing, by an electro-acoustic stimulation (EAS) system associated with a user, sounds sensed by a first microphone coupled to a cochlear implant portion of the EAS system;
applying, by the EAS system, electrical stimulation representative of the sounds sensed by the first microphone by way of a plurality of electrode contacts located in a basal region of a cochlea of the user;
processing, by the EAS system, sounds sensed by a second microphone coupled to a hearing aid portion of the EAS system;
broadcasting, by the EAS system by way of a speaker, amplified sound signals representative of the sounds sensed by the second microphone into an ear canal of the user; and
acoustically separating, by the EAS system, the second microphone from the speaker to avoid feedback within the hearing aid portion of the EAS system.

Abstract
An exemplary method includes an electro-acoustic stimulation (EAS) system associated with a user 1) processing sounds sensed by a first microphone coupled to a cochlear implant portion of the EAS system, 2) applying electrical stimulation representative of the sounds sensed by the first microphone by way of a plurality of electrode contacts located in a basal region of a cochlea of the user, 3) processing sounds sensed by a second microphone coupled to a hearing aid portion of the EAS system, 4) broadcasting, way of a speaker, amplified sound signals representative of the sounds sensed by the second microphone into an ear canal of the user, and 5) acoustically separating the second microphone from the speaker to avoid feedback within the hearing aid portion of the EAS system. Corresponding methods and systems are also disclosed.

9. A method of applying electro-acoustic stimulation to a patient for the purpose aiding the patient to hear comprising:
-
electrically stimulating, by an electro-acoustic stimulation (EAS) system associated with a patient, one or more areas of an inner ear of the patient that are responsible for perceiving high frequency sound; amplifying, by the EAS system, low frequency acoustic signals; presenting, by the EAS system, the resulting amplified low frequency acoustic signals into the ear canal; and at least partially eliminating, by the EAS system, feedback of the low frequency acoustic signals; wherein the low frequency acoustic signals are perceived through normal hearing processes initiated by presenting the amplified low frequency acoustic signals into the ear canal; and wherein the high frequency acoustic signals are perceived through electrical stimulation presented to the inner ear. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
