Rollover index speech audiometry

Speech audiometry showed a 100% underwent pure tone and speech audiometry, click ABR case of the Patient Two, with a rollover index 0.42 [29,30 ]. 4 Oct 2017 Another parameter used in interpretation of the speech audiometry is the maxim of intensity increases, the patient understands less word (roll-over phenomenon). Left ear caloric hyporeflexia-hypofunction index > 30%.

theory and practice of speech audiometry. Speech audiometry is used to measure the ability of a patient to perceive speech signals. Speech materials (pre-recorded or read by examiner) are presented; the patient repeats the speech materials to determine how well it was perceived. Why speech audiometry? Speech audiometry assesses a patient’s Speech Detection Threshold (SDT) The lowest level at which the presence of a speech signal can be heard 50% of the time. (The listener can tell that something is there) The listener does not have to identify the material as speech, but must indicate awareness of the presence of sound. A rollover index >.35 differentiated retrocochlear hearing loss from cochlear hearing loss, although some retrocochlear subjects scored well below that level. Factors that may contribute to differences among PI-PB studies are discussed. RI (Rollover Index): (PBMax-PBMin) / PBMax Speech audiometry generally confirms pure tone audiometry results, and provides insight to the perceptual abilities of the individual. In the case of mismatch between the results of these tests, the diagnostic test used, equipment calibration or the reliability of the responses should be called into question. 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.

What is the rollover index equation? Definition. PB max-PB min/PB max: Term-Variability increases as sample size ___-The ___ the word list, the greater the Rollover Rollover occurs when a client’s speech discrimination score decreases even though the presentation level is increased. The presence of rollover can indicate a lesion on the side of the brain opposite the ear with the roll-over, or 8th nerve lesions on the same side.
