ENT-VSL-7 Data Details

ENT-VSL-7 Reduce the proportion of adolescents who have elevated hearing thresholds, or audiometric notches, in high frequencies (3, 4, or 6 kHz) in both ears, signifying noise-induced hearing loss

Methodology Notes

An audiometric threshold notch is present when one or more of the thresholds at 3, 4, or 6 kHz exceeds the pure-tone average of the 0.5 and1 kHz thresholds by 15 dB or more, and the 8 kHz threshold is at least 5 dB lower (better) than the highest threshold in the 3 to 6 kHz range. Bilateral (present in both ears) notches are used to signify probable noise-induced hearing loss (NIHL).

Children and adolescents with extremely high thresholds, 70 dB or greater, are excluded from the numerator, because the majority of such cases are not attributable to loud noise exposure.
