Word Recognition Test Presentation (based on 2kHz)
2 kHz = < 50 dB HL = +25dB SL
2 kHz = 50 - 55 dB HL = +20 dB SL
2 kHz = 60 - 65 dB HL = +15 dB SL
2 kHz = 70 - 75 dB HL = +10 dB SL
2 kHz = >/= 80 dB HL = UCL - 5 dB HL
2 kHz = 50 - 55 dB HL = +20 dB SL
2 kHz = 60 - 65 dB HL = +15 dB SL
2 kHz = 70 - 75 dB HL = +10 dB SL
2 kHz = >/= 80 dB HL = UCL - 5 dB HL
