dBc suab yog dab tsi?
dBc ua (decibels txheeb ze rau tus cab kuj) yog lub zog piv ntawm lub teeb liab rau lub teeb liab, qhia hauv decibels. Piv txwv li, theem suab nrov yog qhia nyob rau hauv dBc ua / Hz ntawm qhov muab zaus offset los ntawm cov cab kuj. Yog tias dBc ua daim duab yog qhov tsis zoo, ces tus txheeb ze lub teeb liab lub zog yog tsawg dua cov teeb liab lub zog.
