We have developed sound direction estimation device CASH-H and vibration-type indicate terminal for elderly people and hearing impaired people. CASH-H is a device that estimates a sound source direction using two microphones and transmits the direction to a user. The sound source direction is calculated from time difference between two microphone signals. The results indicated that the sound source direction estimation accuracy was approximately ±10°.The sound source direction presentation method presents the sound source direction to the user based on the difference between the left and right vibration intensity. Sound source direction presentation accuracy is 73% correct answer rate and high danger avoidance accuracy.
