Abstract
This paper is an in depth exploration of the fashion object and device, Wireless based hearing on teeth . The principle of bone conduction has been used for many years to treat patients with single-sided deafness and conductive hearing loss. The principle is based on research showing that bone conduction stimulation of the teeth of the lower jaw initiates auditory sensations.teeth vibrations lead to audio-frequency vibration transmissions via soft tissue. Those transmissions then travel through skull foramina into the skull cavity. From there, they channel into the inner ear fluids, stimulating the cochlea. Subsequently, Medical developed Sound Bite Hearing System to use those principles in a non-surgical, removable hearing system. which replaces the function of the impaired ear by using a well-established principle called bone conduction to re-route sound through the skull bones to the functional cochlea. It details inspirations, socio-cultural implications, technical function and operation, and potential applications for the wireless based hearing on teeth.
INTRODUCTION
The Frequency receiver, (see Figure 1) combines a blue tooth transmitter, Receiver with the small dc motor, which is usuallyassociated with voice signal. Grills are almost always made of precious metal, most notably gold or platinum. They are completely removable, and worn as a retainer.
Hearing Through Teeth
Bone conduction hearing has been used since the 1880’s in commercial products to aid hearing loss, except in patients suffering from damage to their auditory nerves. Rhode’s Audiophone (see Figure 2), also known as the acoustic fan, was a popular instrument in the United States. It looked like a fan with a retractable convex shape made of vulcanite, a rarecopper. This fan, acting as an eardrum, would gather the sound vibrations in the air of its surroundings and vibrate at their
frequencies. While users bit the end of the fan, these vibrations passed to the teeth, which then vibrated the cochlea and became audible frequencies once again. where it translates the wireless signal back intovibrations on the teeth. This device is fairly new; it was recently approved by the FDA, and the earliest reviews are from like the Baha, SoundBite aids single-sided and conductive hearing loss.
General Block Diagram
The voice signals are recognized from the user by using microphone, this signal is converted voice to electric signal. In electrical signal has operated at the transmitter frequency is 88 MHz to 108MHz, if any one particular frequency has transmitted the electrical signal, it has operated on frequency modulation technique.
Music and fashion
Music and fashion are the most cyclical of all art and culture based Industries. Ideas and aesthetics are constantly recycled, reappearing decades later. Both of these cultural expressions areseamlessly embedded in our daily lives, and they are venues to our personal identity. Walking down most high school hallways one can see teenagers embracing different subcultures in an attempt to find their personal identities. Punks, metal heads, hommies, hippies,ravers, hipsters, goths, etc. are among the many subcultures thatrepresent the differing aesthetics of popular music genres through a dress code.
There are other subcultures that arose from poverty and struggle, such as gangsters and skinheads, which are more related to socio-economic issues than cultural identity. These subcultures’ dress codes are more prominent and radical in the youth population. Class struggle is a pinnacle of hip hop causing its style to center on the display of wealth.
Conclusion
This hearing system a lot from the other hearing aid’s present in the market due to the above special features present in it. It is also so simple to wear and maintain. It obeys fix and forget principle so we have no feel of wearing it.There are many options for wireless connectivity in modern hearing system. No need to wait three months before use since Osseo integration is not required, optimized microphone location,delivers high fidelity sound with a wide frequency range. A patient can be fitted quickly for the oral device and begin using the hearing aid immediately Each of these offers a unique set of benefits that will change quickly as technology advance.
