| Summary, etc | Objectives: To assess whether there are significant differences between<br/>speech scores for different hearing aid prescription methods, specifically<br/>DSL i/o, DSL V, and NAL-NL1, using age-appropriate closed- and<br/>open-set speech tests with young children, designed to avoid floor and<br/>ceiling effects.<br/>Design: Participants were 44 children with moderate or severe bilateral<br/>hearing loss, 8 aged 2 to 3 years, 15 aged 4 to 5 years, and 21 aged 6<br/>to 9 years. Children wore bilateral hearing aids fitted with each prescription<br/>method in turn in a balanced double-blind design. The speech tests<br/>used with each child (and for some tests the levels) were chosen so as<br/>to avoid floor and ceiling effects. For the closed-set tests, the level used<br/>was selected for each child based on their hearing loss. The tests used<br/>were: (1) The closed-set Consonant Confusion Test of word identification;<br/>(2) The closed-set Chear Auditory Perception Test (CAPT) of word<br/>identification. This has separate sections assessing discrimination of<br/>consonants and vowels and detection of consonants; (3) The open-set<br/>Cambridge Auditory Word Lists for testing word identification at levels of<br/>50 and 65 dBA, utilizing 10 consonant–vowel–consonant real words that<br/>are likely to be familiar to children aged 3 years or older; (4) The openset<br/>Common Phrases Test to measure the speech reception threshold<br/>in quiet; (5) Measurement of the levels required for identification of the<br/>Ling 5 sounds, using a recording of the sounds made at the University<br/>of Western Ontario.<br/>Results: Scores for the Consonant Confusion Test and CAPT consonant<br/>discrimination and consonant detection were lower for the NAL-NL1<br/>prescription than for the DSL prescriptions. Scores for the CAPT vowelin-<br/>noise discrimination test were higher for DSL V than for either of the<br/>other prescriptions. Scores for the Cambridge Auditory Word Lists did<br/>not differ across prescriptions for the level of 65 dBA, but were lower<br/>for the NAL-NL1 prescription than for either of the DSL prescriptions for<br/>the level of 50 dBA. The speech reception threshold measured using the<br/>Common Phrases Test and the levels required for identification of the<br/>Ling 5 sounds were higher (worse) for the NAL-NL1 prescription than<br/>for the DSL prescriptions.<br/>Conclusions: The higher gains prescribed by the DSL i/o and DSL V prescription<br/>methods relative to NAL-NL1 led to significantly better detection<br/>and discrimination of low-level speech sounds. |
