Laser Doppler measurements of cochlear blood flow during loud sound exposure in the guinea pig.
This investigation examined the effects of loud sound of different frequencies and intensities on cochlear blood flow as measured by the laser Doppler flowmeter. Cochlear blood flow was measured in anesthetized guinea pigs during a 1 h exposure to either a 2, 4, or 12 kHz pure tone or high-pass noise (10-40 kHz) at 90, 103, or 110 dB SPL. Cochlear function was assessed using the compound action...

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
the relationship between critical thinking and reading strategies
during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
Loud sound-induced changes in cochlear mechanics.
To investigate the inner ear response to intense sound and the mechanisms behind temporary threshold shifts, anesthetized guinea pigs were exposed to tones at 100-112 dB SPL. Basilar membrane vibration was measured using laser velocimetry, and the cochlear microphonic potential, compound action potential of the auditory nerve, and local electric AC potentials in the organ of Corti were used as ...
متن کاملthe relationship between collocational competence and listening comprehension
پس از پیدایش روش تدریس tpr توسط جیمز اشر که توجه و تآکید بسیاری بر مهارت شنیداری داشت زبانشناسان همواره در صدد یافتن راههایی برای بهبود این مهارت در زبان آموزان می باشند. از طرفی جی-آر-فرث که از پیشگامان زبانشناسی می باشد بر تآثیر لغات و بویژه گروه کلمات که اغلب در گفتار با هم می آیند (هم آیی کلمات)تأکید بسیار کرده است. به این دلیل و به منظوربررسی رابطه بین این دو عامل یعنی درک شنیداری و دانش...
