Abstract
Abstract An acoustic ear mold insertable into the ear of an individual with impaired hearing and used in conjunction with a hearing aid amplifier incorporates therein reflection chambers. Amplified sound wave energy conducted to the ear mold proceeds to the hearing part of the brain over two separate routes, one route being by way of the tympanic membrane and the second route being by bone conduction through the mastoid process.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An improved hearing aid ear mold insertable into the external auditory meatus of the ear and having a longitudinal canal for the conduction of sound waves to the tympanic membrane of the ear; said improvement comprising; a first reflection chamber disposed in said ear mold transversally to and communicating with said canal at opposed points; said first reflection chamber having an upper closed end and an open lower end; a second reflection chamber received in the lower end of said first reflection chamber and communicating therewith; a bone contactor bar carried by said ear mold and abutting said first and second reflection chambers and adapted for engagement with the epidermis overlying the bony structure of the auditory meatus whereby sound wave energy conducted through said canal is reflected by said chambers into the mastoid bone process of the ear through said bone contactor bar for bone conduction to the hearing part of the brain.
Claim 2
Dependent Claim
154 words
An improved hearing aid ear mold insertable into the external auditory meatus of the ear and having a longitudinal canal for the conduction of sound waves to the tympanic membrane of the ear; said improvement comprising; a first reflection chamber disposed in said ear mold transversally to and communicating with said canal at opposed points; said first reflection chamber having an upper closed end and an open lower end; a second reflection chamber received in the lower end of said first reflection chamber and communicating therewith; a bone contactor bar carried by said ear mold and abutting said first and second reflection chambers and adapted for engagement with the epidermis overlying the bony structure of the auditory meatus whereby sound wave energy conducted through said canal is reflected by said chambers into the mastoid bone process of the ear through said bone contactor bar for bone conduction to the hearing part of the brain.
Claim 3
Dependent Claim
29 words
An improved hearing aid ear mold as in claim 1 wherein said first and second reflection chambers are cylindrical and said second chamber is normal to said first chamber.
Claim 4
Dependent Claim
19 words
An improved hearing aid ear mold as in claim 1 wherein said chambers and bar are made of gold.
