The Bone Conduction Technology

Monday, 16 February 2009

Many technologies used for mobile phone, start the connection technology, processor, operating system, until the screen technology .So wonder if we now familiar with the term 3G, HSDPA, Bluetooth, Symbian or Touchscreen.
  Last year phone and a gadget that uses vibration speaker, with bone conduction technology to adopt. This technology is able to improve the sound quality, simply by attaching a phone to the body, such as headache, because the sound vibration
transmitted directly through the skull and the jawbone to the ear called the cochlea.
This means without passing through the outside and middle ear, which was created as part of God's media recorder.
  There have been a military research, entitled 'Bone Conduction Head Sensitivity Mapping: Bone Vibrator'says that vibration placement in the temple which is located between the eye and leaves the top of the ear is dangerous for health.
  However, this technology ever used a Samsung WEP400 headset.This gadget uses bone conduction microphone which tranmitted voice by creating a vibration in the jawbone .Before that, bone conduction technology is also ever attempted on the Aliph Jawbone headset.
  To overcome the impact of technology is bad, there are international standards of the International Comission for Non-Ionizing Radiation Protection (ICNIRP) which have been adopted 80 country.Several famous brand mobile phones already use in order to meet ICNIRP limit threshold level of SAR (Specific Absorption Rate). In the United States Federal Communication Commission ( FCC ) determine the highest SAR limit is 1.6 W / kg, for the European region is the SAR limits 2W/kg
