What is the normal hearing range in dB HL according to ASHA?

Explanation:
Hearing thresholds that fall within normal limits are those where a person can hear very soft sounds across the speech-frequency range. According to ASHA, normal hearing is typically defined from about -10 dB HL up to around 15 dB HL. The negative lower bound allows for slightly better-than-average sensitivity, while the upper bound around 15 dB HL reflects the upper limit of what’s still considered normal before mild hearing loss begins. The other ranges either start below -10 or extend beyond 15, which would not align with the standard cutoff used here for normal hearing.
