An Investigation to Evaluation of Noise Induced Permanent Threshold Shift by Pure Tone Audiometry

Pure Tone Audiometry

Pure tone audiometry is the standard behavioral assessment of an individual’s hearing. The results of pure tone audiometry are recorded on a chart or form called an audiogram. In most cases a pure tone audiogram is easy to obtain and provides information about peripheral hearing acuity across the frequencies used in speech. It allows for a quick view of how well, or how poorly, an individual ca...

Theory and practice of pure tone audiometry

Pure tone audiometry indicates what hearing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is based on normal human hearing...

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...
