Qhov ntau ntawm tib neeg hnov frequencies yog:
20Hz - 20,000 Hz (Hz yog chav tsev zaus)
Yog li ntawd, qhov ntau zaus ntawm cov neeg hais lus yuav raug txhais nyob rau hauv qhov ntau, qhov zaus hauv qab no yog hu ua infrasonic nthwv dej, siab tshaj qhov ntau zaus no hu ua ultrasonic.Infrasound thiab ultrasonic tsis yog feem ntau inaudible rau tib neeg pob ntseg.
Lub equalizer ntawm lub suab sib xyaw yog siv los kho lub suab zaus, uas yuav cuam tshuam ncaj qha rau lub suab zoo.Raws li txoj cai dav dav, qhov sib npaug' s bass thaj tsam nyob ib ncig ntawm 100Hz, tshwj xeeb tshaj yog 100Hz bass yog qhov feem ntau. Elastic.The equalizer's 100Hz slider los tsa ib co yog tias koj nyiam cov ntses bass thaj tsam thaum mloog suab paj nruag (xws li: nruas, ntses bass thaj tsam, thiab lwm yam).Qhov sib npaug' s mid-tone cheeb tsam yog nyob ib ncig ntawm 1000Hz (1kHz), tshwj xeeb tshaj yog 1000Hz (1kHz), thiab lub suab ntawm nruab nrab-tone cheeb tsam feem ntau yog hais txog tib neeg lub suab.Qhov sib npaug' thaj av siab siab feem ntau yog nyob ib ncig ntawm 4000 (4kHz), tshwj xeeb tshaj yog lub high- suab ib ntawm 4000Hz (4kHz).
