AFO Qhov taw qhia
AFO (acoustic daim duab ntawm kev tsim nyog) yog qhov ntsuas tau siv los ntsuas cov khoom ua haujlwm ntawm acoustic cov ntaub ntawv. Nws qhia txog lub suab rwb thaiv tsev thiab pa cov khoom ntawm cov khoom.
AFO Performance index feem ntau yog siv los sawv cev cov suab ntawm lub suab rwb thaiv tsev ua haujlwm rau cov khoom nqus kom haum rau cov ntaub ntawv. Cov qauv yog: AFO=(sc - mnc) / (STC + MNC)
Ntawm lawv, Stc (Suab Xov Xwm Sib Tham) yog qhov ntsuas ntawm lub suab rwb thaiv tsev ua haujlwm, qhia txog kev ua kom lub zog thaum lub suab dhau los ntawm cov khoom siv. Mnc (Yam tsawg kawg ntawm cov suab nrov) yog qhov taw qhia ntawm lub suab nqus cov kev ua tau zoo, qhia txog cov khoom uas nqus tau nrov.
Qhov siab dua ntawm AFO Performance index, qhov zoo dua lub suab rwb thaiv tsev thiab kev nqus tau ntawm cov khoom. Feem ntau, AFO qhov tseem ceeb tshaj 0.5 yog suav tias yog suab zoo suab rwb thaiv tsev thiab cov ntaub ntawv nqus.
AFO Performance index yog feem ntau siv nyob rau hauv cov liaj teb zoo li lub suab rwb thaiv tsev, sab hauv tsev kom ntsuas lub suab rwb thaiv tsev thiab kev ua tau pa ntawm cov ntaub ntawv thiab txiav txim siab xaiv cov khoom siv
