USPS Air Mail to Hawaii for 3.00 additional. Kingston Hearing Innovations Stock Certificates 8in H X 11 in W. Suitable for framing This stock was purchased in good faith. The certificates One is dated April 12 1993 and one is dated June 30 1997. The funds from the purchase were to be used for a start-up company as a bridge loan to begin production of a hearing aid that was ahead of its time in design. Most of the device could fit in a shirt pocket with a wire to carry the electrical signal to a small device that would fit over the ear. This device had a thick wire attached to it and the thick wire rested over the mastoid process area of the skull which is located just behind the ear. The company had an air-tight patent on their design. And the prototypes produced and tested functioned as they should. So why was the Hearing Innovations device a failure The theory supplied by the company was that medical professionals in the field preferred to use cochlear implants because the profit for both the surgeon and the medical facility from doing surgery were far greater than what would be realized from the sale a device that could be fitted and adjusted to a patient in one or 2 visits and easily repaired or replaced if it ceased functioning or was damaged. Also at the time the patient s insurance company would cover most if not all of the expenses involved with the cochlear implant but not those of the Hearing Innovations device which was around 1000. Most people with a major hearing loss were having and still have. Cochlear Implants done (which is accomplished with invasive surgery) Cochlear implants which are NOT always 100% successful are surgically implanted electrical devices that allow people with a severe-to-profound hearing loss to process sound. Referred to as an auditory prosthesis it provides a sensation of hearing and some implantees achieve near-to-normal speech understanding in quiet acoustic conditions. The implant works by transforming sound into electrical stimulation. A microphone-like device or sound processor picks up external sounds and digitizes it. These digital signals are then sent to a tiny wire with many electrodes which is implanted into your cochlea. Each electrode corresponds to a different signal frequency. Your brain then receives the signal through the auditory nerve. The problem comes in when two electrodes stimulate the same neural population or overlapping neural populations thus confusing the sounds reducing your understanding of what you might have heard . For those of you that know little or nothing about the workings of the inner ear here is a description of how sound waves are transferred from the outside world and make their way to the brain The three parts of the ear anatomy are the outer ear the middle ear and the inner ear. The inner ear is also called the cochlea. ( Cochlea means snail in Latin the cochlea gets its name from its distinctive coiled up shape.) The outer ear consists of the pinna ear canal and eardrum The middle ear consists of the ossicles (malleus incus stapes) and ear drum The inner ear consists of the cochlea the auditory (hearing) nerve and the brain Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles malleus incus stapes) in the middle ear. The last bone in this chain knocks on the membrane window of the cochlea and makes the fluid in the cochlea move. The fluid movement then triggers a response in the hearing nerve. When your hearing is working normally information is being passed through the different parts of the ear to the brain. The type of hearing problem you may have depends on which part of the ear is not responding well. Outer ear or middle ear problems lead to inefficient transfer of sound. The cochlea is still working but may not receive enough information. This type of hearing loss is called conductive hearing loss. The problem is that the sound is not being conducted (transferred) well enough. Conductive deafness can be caused by things such as an ear infection a hole in the eardrum or otosclerosis. An inner ear (cochlear) problem means that sound arrives at the cochlea but is then not fully passed on to the hearing nerve. Also it is possible that the hearing nerve itself is not passing on information well or fails to pass on the sound at all. A cochlear or neural hearing loss is called a sensorineural hearing loss. Sensorineural hearing loss can be caused by things such as advanced age M ni re s Disease or prolonged exposure to loud noises. It is possible to have a mixed hearing loss with both a conductive and sensorineural element. P.S. This company is NOT this one s hearinginnovations.com . I have already contacted them.
