University of the Pacific Audiometric Criteria

Description of Hearing Loss​

Flat  - </= 5 dB per octave
Gradual  -  6 - 10 dB per octave
Steep  -  11 - 15 dB per octave
​Preciptious . -  > 16 dB per octave

Asymmetric Criteria

>/= 15 dB at one frequency
>/= 10 dB difference at 3 separate frequencies

Test-Retest Reliability / Significant Δ

> 10 dB Δ is significant
</= 10 dB test-retest reliability

Severity of Hearing Loss

Adults
0-20 Normal
21-25 Slight Borderline/Normal
26-40 Mild
41-55 Moderate
56-70 Moderately Severe
71-90 Severe
>/= 91 Profound

Pediatrics
0-15 Normal
16-20 Slight
21-40 Mild
41-55 Moderate

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
