Hearing-Status Group Definition | Thresholds ≤15 dB HL for octave frequencies 250–8000 Hz. | Three-frequency PTA ≥20 and ≤45 dB HL OR thresholds >25 dB HL at one or more frequencies above 2 kHz in both ears. | Three-frequency pure-tone average (PTA) >20 dB HL in the poorer ear and ≤15 dB HL in the better ear OR thresholds >25 dB HL at one or more frequencies above 2 kHz in the poorer ear. |
PTA | For 7 children, mean better ear PTA = 34.2 dB HL (SD = 8.3 dB) and poorer ear PTA = 36.7 dB HL (SD = 7.1 dB). One child had a high-frequency hearing loss with better ear high-frequency average thresholds for 6–8 kHz (left ear) = 45 dB HL and poorer ear threshold at 8 kHz (right ear) = 50 dB HL. |
For 8 children, poorer ear PTA = 55 dB HL (SD = 11.7 dB). Two participants had high-frequency hearing loss. For one, the high-frequency average thresholds for 3–8 kHz = 82.5 dB HL (right ear), and for the other average thresholds for 4–8 kHz = 88.3 dB HL (right ear). |
