Clinical Observations on Excessive Threshold Adaptation

Recruitment and Per-Stimulatory Fatigue in Diagnosis

“…that non-recruiting nerve cases are especially susceptible to per-stimulatory fatigue. A few individual cases have later been added to the latter group: thus Jerger et at. (1958) and Yantis (1959) found abnormal fatigue to appear in a total of 5 cases of acoustic nerve tumour, and expressed the hope that this phenomenon might become a reliable diagnostic sign.…”

Acquired Hearing Loss, Anger, and Emotional Distress

“…Patients were seated inside a double-walled, sound attenuating booth that meets the standard ANSI S.1-1999. Air conduction thresholds were recorded using 6 the routine 10 dB descending and 5 dB ascending method (modified Hughson-Westlake method), starting at 1000 Hz at 40 dB HL in the left ear and were obtained from 0.25 to 8 kHz bilaterally (Jerger J et al, 1958)). No segregation of cases was carried out on the basis of hearing loss type (sensorineural, conductive and mixed).…”

Assessment of Auditory Processing in Cerebral Palsy

“…At the outset, there were conflicting results between cochlear and eighth nerve impaired ears, partially due to instrumentation and techniques. Eventually, Jerger et al (1958) demonstrated a relationship between cochlear and eighth nerve impairments by comparing the tracking sweeps using continuous and interrupted signal presentations.…”
