Bone-conduction transducers offer a unique advantage for radio communication systems, allowing sound transmission while the ear canals remain open for access to environmental sounds, or plugged for blocking of environmental sounds. This study compared the intelligibility of noise-degraded speech presented through bone-conduction hearing administered at different locations, and through air-condu...
چکیده اسیدهای چرب غیراشباع با چندین پیوند دوگانه می توانند در روندهای تولید مثلی مختلف از طریق سازوکارهای متنوعی تاثیر بگذارند. در این مطالعه تاثیرات مکمل های اسیدهای چرب امگا 3 و امگا 6 بر ویژگی های تکامل فولیکولی و استروئیدزایی تخمدان و همچنین بیان فاکتور رشد bone morphogenetic protein 15 در اووسیت، که در فولیکول زایی تخمدانی نقش دارد، بررسی شد. 30 میش 4-2 ساله-ی غیرشیرده به 3 گروه 10 تایی ت...
Sound pressure levels in the external auditory canals of 50 subjects were measured at 2000 and 4000 Hz with a bone-conduction vibrator on the forehead, the mastoid ipsilateral to the probe microphone, and the mastoid contralateral to the probe microphone. A plug was placed in the external auditory canal to minimize sound pressure levels in the external auditory canal produced by the osseotympan...
Codebook-based single-microphone noise suppressors, which exploit prior knowledge about speech and noise statistics, provide better performance in nonstationary noise. However, as the enhancement involves a joint optimization over speech and noise codebooks, this results in high computational complexity. A codebook-based method is proposed that uses a reference signal observed by a bone-conduct...
The feasibility of recording bone-conducted auditory brainstem responses (ABRs) to 500-Hz and 2000-Hz tone bursts and clicks was investigated in normal-hearing adults. For all 3 stimuli, responses were detectable in all subjects at 30 dB nHL. At 20 dB nHL, the tone burst responses were detectable in 80-87% of the subjects, demonstrating that even the responses to 500-Hz tone bursts were relativ...
