Abstract

OBJECTIVE: This systematic review evaluated the effectiveness of two frequency-lowering schemes, non-linear frequency compression and frequency transposition, at improving speech intelligibility for adult hearing-impaired populations. DESIGN: A systematic search of 10 electronic databases was carried out using pre-defined inclusion criteria. Accepted articles were then critically appraised using the Effective Public Health Practice Project (EPHPP) Critical Appraisal Tool. Outcome results were further synthesised where possible using random effects meta-analysis to provide overall combined estimates of the treatment differences along with 95% confidence intervals. STUDY SAMPLE: A total of 20 ..
