Since the birth of mankind, has been trying to battle with disease and aging. And partial loss of function of the body, human effort, there are two ideas: "repair or replace". Unfortunately, the "fix" does not apply to all cases, limbs cannot grow new limbs, hearing loss, ears not recycled ... ... Then look for "alternative" became the only viable way.
In a pirate movie, we can see a vicious pirate captain face have wood feet. In contemporary society, crutches, wheelchairs and even blade prosthetic common, vision's friends on the nose also the optical lenses of the glasses, hearing loss friends also wore a hearing aid, there are artificial joints, artificial heart, lung, and kidney. Even the latest movies of the Polytechnic Institute in imagining the implanted chip.
We should be grateful, technological and medical advances, "alternative" technology is more and more mature. Author at the hearing healthcare industry, volunteer Science Popularization of the current "smart devices" only counted in application of the evolutionary history of the industry.
Smart first step: click sounds
Hearing aids, you may have the impression. A few decades ago, has a white-haired old man ears headphones hanging in front of the long line, shirt pocket has a radio box. This is now rarely used "analogue hearing aids", simply, is a linear amplifier, sound amplifier. Users than the original hearing, "amplified sound" clearly intelligent
Second step smart: linear amplification
Later, found that the loss of hearing loss at different frequencies are not the same, bad linear amplifiers for analog circuits, digital hearing aids have emerged based on the DSP chip. After rigorous listening tests, based on different frequencies to different amount of compensation, making linear amplification of the sound more suitable for users of hearing aids.
Third step smart: noise reduction and scene recognition
Later, found a problem hearing aids: wear hearing aids do feel there is noise? Through establishing sound data models, through the identification of environmental noise, "noise reduction" programs, but users in different demand scenario for effective voice is not the same. Do? Have emerged through a smart phone's location to determine scenarios, and the hearing aid sound handler handler to automatically switch between different scenes.
I like happy hearing aids, Oticon
Fourth step smart: made for iPhone
The use of mobile phones, is also important for the hearing impaired, call wearing a hearing aid, always a little inconvenience. In the latest hearing aids, already have a 2.4Ghz Bluetooth connection between the phone and hearing aid.
Fifth step smart: technology integration
Going to have a very small hearing aids? Hearing aids can do not damage easily? Hearing aids can have batteries with long? Hearing aids can be based on Chinese language policy? Ted Baker note 3 covers
Smaller and smaller chips, making small size and power consumption, and good performance;
Nano-dustproof and waterproof coating makes use of a hearing aid is not easily broken;
Chinese voice models for data analysis, program for Chinese language processing.
Ultimately, the hearing aid as a smart device, not on a technology by leaps and bounds, but chip, power supply, language processing, microphone technology, such as the development of an integrated.
Reconstruction of listening with smart device? Ted Baker Note 3 Case
Said hearing aids, we think if a person's hearing loss hearing AIDS cannot function do? Such as severe and extremely severe in patients with otitis media in patients with nerve deafness, they cannot use an existing hearing aid.
I would say that cochlear implant was the first in human history: real artificial organs? It can replace human functions, high Biger.
Basic principle is a coil implanted under the skin and the electrode, electrode directly stimulate the auditory nerve obtained hearing. Worn speech processor on the ears, between the head and the coil implanted under the skin to "trans-skin communication" signal transmission.
Relates to implanted under the skin, then use the material and human exclusion does not appear. For example: titanium alloy, ceramics, silicone. In addition to the material, is the process of production, chip subcutaneous fluids seeping, just does not work (from the point, tech movies directly in the ear implants don't make sense). None of this is the highest level of technical requirements, but do these techniques, it is difficult.
For otitis media and otitis externa in patients with abnormal inner ear function and need not do cochlear implants, hearing AIDS cannot, do? Still there is a way.
This is the vibrant SoundBridge technique. Principle, it is probably in the cochlea of the inner ear, there's a metal vibrator, instead of three tiny bones in the middle ear for sound transmission.
This is bone-anchored hearing aid BAHA technology. General principle is embedded in the skull of a titanium alloy nail, outside is the processor, by skull vibration transmission.
This is the Sophono bone-anchored hearing aids, unlike BAHA was, bare nails or skin without something else, implants, implant, processor and implants by "trans-skin communication" approach.
Smart devices can also replace what organ?
Above, is hearing medical science, and in the last few years, "artificial vision" technology is already in clinical trials. Retinal prosthesis technology, intraocular implant chip help the blind regain visual approach. Pity is that current technology can only help the user with a sense of light and contour, cannot yet be completely reconstructed vision.
To sum up, intelligent artificial organs, is coming towards us. Materials technology, development of power technology, chip technology, communication technology, mankind in the near future to achieve "handicapped rehabilitation, blind sight, deaf fucong. "The real development of smart devices, maybe just need to improve on existing equipment, intelligent, and more importantly," demand "," technology "," expanding discipline integration "come true.

Main light Office Sufi series third-generation products to market, is still a familiar shape, compared to the previous generation, reduce body thickness from 10.6mm to 9.1mm, whole body slim. Design, improved Type keyboard Cover, upgraded frame, larger screens, and refers to a traditional laptop. While the weight is only 800g, over the previous weight has been greatly improved, and Microsoft has been emphasizing lighter than MBA. Well if you want to buy, we must first consider whether to accept a resolution of 2160x1440 pixels, 3:2 per cent of 12-inch screen.
