Otoacoustic emissions (OAE) tau siv los ua ib qho kev kuaj pom ntxov rau kev hnov ​​​​lus tsis zoo.

Pab neeg no tau kawm cov ntaub ntawv los ntawm 145 cov menyuam yaus uas hnov ​​lus tsis zoo uas muaj hnub nyoog 8 txog 10 xyoo, muab faib ua ob pawg: pawg tswj hwm ntawm 85 tus menyuam yaus tsis txhob haus luam yeeb, thiab pab pawg muaj pa taws ntawm 60 tus menyuam.
