A Bluetooth compatible bone conduction headset, developed by GD Tech Co., Ltd. (http://www.gdtech.co.kr) will be exhibited at CeBit 2010 in Hanover, Germany. This is good news for those who suffer from noise-induced hearing loss and damaged eardrums, as well as those who receive a number of mobile phone calls while using headsets.
Bone conduction has the mechanism to transmit the vibration of the bone to auditory cochlea as a sound by-passing the eardrum, thus headset employing bone conduction technology drastically reduces the stress of the ear and prevents damage to the eardrum. About 10% of younger people who are suffered from noise induced hearing loss and have damaged eardrum can also hear the sound clearly with bone conduction headset.
As the ear is not blocked, the user of the headset can hear surrounding noises, and avoid possible risk during the outdoor activities such as mountain climbing, skiing and jogging. It also does not cause fatigue and reduction of hearing ability even with long-term usage as the sound is directly transmitted to the auditory organ by-passing the eardrum.
Earbone (model name: GDB-401) and WaveBone (model name: GDB -402) of the GD Tech are upgraded versions of the company¡¯s existing bone conduction headsets with Bluetooth feature, an industrial specification for wireless personal area networks (PANs).
In addition to enjoying many benefits of conventional bone conduction headphone, Earbone allows users to receive cell phone calls and listen to music from the phone, helping them more conveniently in this era of the cell phone.
Ergonomics design employing eight joints to meet the various shapes of the human heads and semipermanent Lithium battery are some of the other benefits of the products. A removable microphone is also available for the convenience of call center telemarketers.
Basic specifications of the product are as follows: 60g in weight, 30mW of optimum output, 70mW of maximum output, 50Hz to 4kHz of standard frequency, 80db/mW of sensitivity, and 120mm of cord length. Environmentally friendly materials are used.
In addition to Earbone and WaveBone, GD Tech also produces AudioBone (model name: MGD-03) and WeBone (model name: GDH-704), advanced bone-conduction headphones without Bluetooth feature, and AquaBone (model name: MGD-01), a waterproof version for swimmers. WeBone and AquaBone are shipped in eight colors namely gray, white, black, orange, blue, pink, green, purple and brown.
The bone-conduction hearing aid (GDHA-601) and various kinds of in-ear earphones are also available to be provided and customized.
