" Obviously the hearing is an important way of human to receive external information, but also affect ability to communicate. Hearing impairment is bound to affect the lives learning and communication efficiency, but will also lead to a decline in the quality of life and the interpersonal relationship. Hearing impaired will make inconvenience of life and safety concerns, therefore, how to design and enhance the hearing impaired to improve usability to enhance their welfare should be an important issue. The objective of this study is to investigate the effect of orientation of the sound source, distance, frequency and source of clues to the impaired spatial perception. The results of experiment one indicated that the frequency of a sound, the distance of the sound source, the ears of the advantages of the sound source position and the subjects are significant to determine the sound source position tolerance,also it has two-way interaction of the sound frequency × sound source and sound frequency × sound distance. Experiment two indicated significant of stimulate sound time and stimulate the subjects was affect to impact of sound frequencies before the auditory threshold after hearing threshold tolerance, In addition, the experiment found that the two way interaction of stimulate the auditory type x audio rendering time. The results can guidance the design of the hearing impaired products to enhance the life of the well-being of the hearing-impaired. Example: the design of communications equipment, medical audiometry, calibration, broadcaster, alarms, doorbells, GPS navigation, mobile phones and parking sensor design.
