Because audiologists have contact with children for only a small number of hours every few months or once a year, the majority of information concerning a child’s speech perception will be documented by LSLSs, SPLs, TODs, and parents. Analysis of phoneme errors on informal and formal measures and review of a frequency allocation chart for speech phonemes can identify specific frequency bands to be adjusted. While many CI users perform well if stimulation levels are balanced in loudness across the electrode array, some will benefit by making needed changes in specific frequency bands, rather than globally increasing or decreasing all bands.
