Hearing Protection for Bone-Conducted Sound
The high-noise environments in and around modern military jet aircraft can impair voice communications and cause permanent damage to the hearing of pilots and maintenance crews if adequate hearing protection is not worn. With external noise levels of some aircraft approaching 150 dBA, adequate hearing protection must provide better than 50 dB of attenuation. In order to reach such a high level ...
متن کاملVestibular activation by bone conducted sound.
OBJECTIVE To examine the properties and potential clinical uses of myogenic potentials to bone conducted sound. METHODS Myogenic potentials were recorded from normal volunteers, using bone conducted tone bursts of 7 ms duration and 250-2000 Hz frequencies delivered over the mastoid processes by a B 71 clinical bone vibrator. Biphasic positive-negative (p1n1) responses were recorded from both ...
متن کاملSound Wave Cancellation Through Bone and Air 1 Running Head: SOUND WAVE CANCELLATION THROUGH BONE AND AIR Toward Adapting Spatial Audio Displays For Use With Bone Conduction: The Cancellation of Bone-conducted and Air-conducted Sound Waves
Virtual three-dimensional (3D) auditory displays utilize signal-processing techniques to alter sounds presented through headphones so that they seem to originate from specific spatial locations. A full function of shift values could be used to adapt virtual 3D auditory displays for use with bone-conduction headsets (bonephones). This study provided anchor points for a function of shift values. ...
متن کاملEvaluation of the vibrational modes of the human skull as it relates to bone-conducted sound.
Analytic and numerical models are used to study bone-conducted sound and how it relates to the vibrational modes of the human skull. The analytic model is based on the solution to the acoustic and elastic wave equations and the constraining boundary conditions for a fluid-filled elastic sphere. Both models predict that most of the acoustic energy of bone-conducted sound exists in the form of su...
