Nws paub tias tus neeg nruab nrab muaj peev xwm pom tau acoustic nthwv dej nyob rau hauv thaj tsam ntawm 16 txog 20,000 Hz (nyob ntawm qhov chaw - 16,000 Hz). Qhov no yog hu ua lub suab nrov.

Cov duab no yog kwv yees. Qhov tseeb yog tias nyob rau hauv tus txheej txheem ntawm kev loj hlob, thiab tom qab laus laus, cov kab mob ntawm lub pob ntseg hloov pauv. Qhov tshwm sim ntawm cov txheej txheem no tsis yog tsuas yog txo qis hauv cov suab nrov. Qee lub sij hawm ib tug neeg yuav tsis pom tsis tau tsuas yog lub ciam teb frequencies, tab sis kuj tus kheej frequencies uas nyob rau hauv tus txheej txheem perceived ntau. Tsis tas li ntawd, cov zaus qis dua 100 Hz tuaj yeem pom tsis tau los ntawm kev hnov lus, tab sis los ntawm kev kov lossis vim yog qhov cuam tshuam ntawm lub suab hauv pob ntseg.

Thaum xub thawj, lawv yog npaj rau qhov zoo tuning multichannel hais lus tshuab. Lawv raug tsim dua tshiab los tshawb nrhiav qhov tsis sib haum xeeb thiab tom qab ntawd txiav tawm siv cov khoom siv kho vajtse lossis software suav nrog hauv kev hais lus (crossovers thiab equalizers). Cov ntaub ntawv suab zoo li no muaj cov kaw suab ntawm ib zaus lossis ib ntu ntawm cov kaw lus zoo sib xws uas tsim los ntawm lub tshuab hluav taws xob lub suab.
