Speech recognition rollover is one of the special tests that, in the pre-ABR and pre-MRI era, comprised the battery of tests that were helpful for screening for retrocochlear pathology. ABR significantly increased the sensitivity of auditory testing to VIIIth nerve lesions and MRI was found to be significantly more sensitive than ABR.

Rollover phenomenon in speech audiology is seen in Retro cochlear lesions The majority of patients with an acoustic neuroma will demonstrate abnormal findings on audiologic testing. A complete audiologic test includes pure-tone audiometry, acoustic reflex testing with a measurement of reflex decay and speech reception audiometry.
PB rollover and the acoustic reflex

Subjects who lacked all acoustic reflexes, however, experienced significantly greater rollover of speech intelligibility at high intensities than did subjects with all or some reflexes intact. A neural-mechanical interaction is suggested as a basis for the rollover phenomenon in subjects with retrocochlear eight-nerve disorder. MeSH terms Humans

Testing at UCL-5dBHL allows for determination of roll-over and if word recognition testing needs to be completed at lower intensity levels. Additionally, if a patient is fit with hearing aids, WRS at UCL-5dBHL allows for validation of hearing aid performance. Degrees of word recognition performance Excellent 90-100% Good 78-88% Fair 66-76%

However, even if not all three above criteria are met, the examining audiologist may choose to refer patients if there are other compelling audiologic data (e.g., positive rollover or reflex decay) and/or symptoms (e.g., dizziness, aural fullness, facial paresis, or other symptoms suggestive of cranial nerve pathology). Intermediate probability

Rollover Measurements with Auditec NU-6 Word Lists. Auditec cassette tape recordings of NU-6 word lists were used to obtain performance-intensity functions for phonetically balanced words (PI-PB) from 25 subjects with normal hearing, 19 subjects with presumed cochlear disorders, and 9 subjects with confirmed retrocochlear lesions.

Unilateral hearing loss of sudden or recent onset within the previous 90 days (FDA, 1977). The AAO-HNS (1993, 1994) clarification of unilateral hearing loss: air-conduction pure-tone PTA (500, 1000, 2000, and 3000 Hz) difference of 15 dB or greater. AAO-HNS (2015) concurred but did not identify test frequencies.
