Universal newborn hearing screening has been implemented to detect permanent childhood loss (PCHL) early, with the ultimate goal of improving outcomes through early treatment. However, there is disagreement between studies on size this benefit and in some cases whether it significantly different from 0. There have no sufficient which researchers determined reliably effect varies degree PCHL. We aimed explore how intervention timing influences 5-year language children PCHL.Via a prospective...
A new procedure for fitting nonlinear hearing aids (National Acoustic Laboratories' procedure, version 1 [NAL-NL1]) is described. The rationale to maximize speech intelligibility while constraining loudness be normal or less. Speech predicted by the Intelligibility Index (SII), which has been modified account reduction in performance associated with increasing degrees of loss, especially at high frequencies. Prescriptions are compared NAL-NL1, desired sensation level [input/output], FIG6,...
Two experiments were conducted to examine the relationship between audibility and speech recognition for individuals with sensorineural hearing losses ranging from mild profound degrees. Speech scores measured using filtered sentences compared predictions based on Intelligibility Index (SII). The SII greatly overpredicted performance at high sensation levels, many listeners, it underpredicted low levels. To improve predictive accuracy, needed be modified. Scaling index by a multiplicative...
