Elderly people tend to have a problem with hearing well on a mobile phone due to their age. Now, here comes a solution to this problem which will enable those people with hearing problems to have normal conversations with loved ones and family. Japanese telecom NTT DoCoMo has unveiled a mobile receiver-microphone at Barcelona’s World Mobile Congress.

This handset is ultra slim with Bluetooth which is known as ‘Sound Leaf Plus’. It just weighs 45 grams. The Bluetooth handset works when pressed against the bone below the ear. Using a principle known as bone conduction, it sends sound vibrations to the auditory nerves through the cranial bones.

This kind of technology has not been used before for any product which can combine bone-conduction technology with a telephone coil. This Bluetooth handset allows the user to connect Bluetooth link or a hard wire to cellular phone service.

The mobile phone which is developed by NEC/Tokin, includes a high frequency switch which improves sound articulation. It is also useful for normal hearing people when they are in the noisy environment.

Initially, the bone conduction had been used for military devices for throat microphones or diver communication sets to provide hand free operation for pilots and underwater operators.

The Sound Leaf has been made available to DoCoMo subscribers in Japan. The cost and availability still remains a mystery.
