2pPPb31. Development of a novel hearing-aid for the profoundly deaf using bone- conducted ultrasonic perception: Assessments of the modulation type with regard to articulation, intelligibility, and sound quality
Bone-conducted ultrasound (BCU) is perceived even by the profoundly sensorineural deaf. We have developed a novel hearing-aid using BCU perception (BCU hearing aid: BCUHA) for the profoundly deaf. In the BCUHA, ultrasonic sinusoids of about 30 kHz are amplitudemodulated by speech and presented to the mastoid. Generally, two sounds are perceived: one is a high-pitched tone due to the ultrasonic ...
متن کاملDevelopment of a Bone-conducted Ultrasonic Hearing Aid for the Profoundly Deaf: Assessments of the Modulation Type with Regard to Monosyllable Articulation and Confusion Analyses
Bone-conducted ultrasound (BCU) can be experienced as sound even by the severely hearingimpaired. We have developed a novel hearing aid using BCU perception (BCU hearing aid: BCUHA) for the profoundly hearing-impaired. Results of evaluation tests suggested its practicability, however, there is room for improvement in terms of articulation. In the BCUHA, ultrasonic sinusoids with a frequency of ...
متن کاملNonlinear explanation for bone-conducted ultrasonic hearing.
Human listeners can perceive speech from a voice-modulated ultrasonic carrier presented via a bone-conduction stimulator. This study explored the psychoacoustic characteristics and underlying mechanisms of ultrasonic hearing by measuring difference limens for frequency (DLF) for pure tones modulated onto ultrasonic carriers. Human subjects were presented with two pulsed tones and asked to judge...

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
