Bone Conduction
Abstract
Bone conduction has a long and broader history, as well as it has an efficient and unique way of sound conduction, almost 5 to 6 centuries before scientist and experts started thinking and working on this method to conduct sound through bones, these all are theoretical finding and paper work. From the past few decades medical expert saves many human lives by using the bone conduction equipment, medically it changes the life of many disabled people on our planet, several technologies have been developed so for to transmit sound through bones system. Now we will discuss this technology in detail and briefly to know their fundamentals and historic background in broader prospects.
Introduction
In the 1500s many experiments have been compiled by experts and experiments have recorded to experience the phenomena of sound transmission via vibrating materials. The first person how got success and write articles, discuss the theory was the “Girolamo Cardano” in 1500s. Initially immature objects were used to support the conduction to Conway the sound to listener, who have hearing loss by using rode or other materials.
After decades in 1900s microphones were developed as the technology getting smarter and becoming advance, experts achieve a big advantage to transmit sound by converting into mechanical waves, in this era bone conduction devices were developed of different sizes and with different design for multiple purposes. Initial devices were not much impressive due to the its design that’s not better adjustable, inefficient sound transmission and sound quality. But these experiment work open a way towards the today modern technology and updated devices that almost change the human life of this period. Several bone anchored hearing aids and surgical devices have been attempted.
In Sweden, Anders Tjellstrom and his partner were succeeded to implant titanium devices in 1977. In 1980s the very first device bone-anchored hearing was developed, and widely commercially provided, lot of patients have been cured by using this device which have been suffering completely hearing losses, partial hearing losses and single sided hearing losses. After this big achievement a series of new ways open and lot of potential have been made to made this phenomenon advance. Now we are to discuss the detail technical and core basics of bone conduction technology and about this system mechanical prospect.
Bone Conduction System Anatomy
Here we will explain you the complete scenario of bone conduction system, how different human mini-parts of bones and other multiple functions contribute to make this whole phenomenon happen in actual. Different body mechanisms involve to complete bone conduction process. Sound is propagated from sound waves in vibrations and passes through skull and bones to cochlea, so that the end result of transmitting waves to cochlea nerve, the process is simple like traditional air conduction system works.
There is a process how this whole anatomy of bone conduction works, and we are clearing the heads of our audience to describe the full pathway. There are five contributing pathways that engage to conduct this process. The experts have described in details
- Sound waves to the external ear canal
- Middle ear ossicle inertia
- Inertia of cochlear fluids
- Compression of the cochlear walls or inner ear compression
- Pressure transmission from cerebrospinal fluid as the principal contributors to bone conduction.
The major contributor in this whole process is inertia of cochlear fluids.
Here we explain how the expert take advantage to process the bone conduction system, bone conduction take hedge by changing sound energy into vibrations and transmit through bones of skull. By using this conduction system lot of devices have been developed and supplied to medical patients and other commercial purposes. In which largely surgical instrument are involved some other extrinsic devices are also included.
These devices are very production for the patients how have completely or partial or mixed hearing losses which can’t use their traditional air conduction hearing system. These devices are also used for medical propagations and other interventional process as well.
In this modern era of technology and modern days of innovations, and with the productive life of today’s human and adventurous life of human many innovations have been made in this century. So, bone conduction headphones are one of the modern inventions in human life. With broader aspect expert find that why this technology should not use for common human development and for human advantages. By leading this idea many commercial companies and manufacturer started developing bone conduction headphones, and it is getting popularity day by day.
