Study Details

Brief summary:

The protocol has two aims; Aim 1 involves two experiments and Aim 2 involves three experiments. Under Aim 1, the investigator will identify that the frequency and time ranges of consonants produce consonant enhancement (i.e., "target frequency range" and "target time range", respectively), and that the frequency and time ranges of consonants cause consonant confusions (i.e., "conflicting frequency range" and "conflicting time range", respectively). Aim 2 tests the effects of the frequency and time ranges, identified through Aim 1 on consonant recognition with each of the four signal processing conditions: no signal processing (i.e., control condition), the target frequency and time ranges intensified alone, the conflicting frequency and time ranges suppressed alone, and both target range intensification and conflicting range suppression.

Interventions and Outcome Measures

Arms

experimental: signal processing on consonant recognition

The effects of the three processing schemes on consonant enhancement will be measured.

The results will be compared with two signal processing schemes: target-cue signal processing, and combined target and conflict-cue signal processing.

Interventions

signal processing on consonant recognition

Consonant recognition will be measured in noise without any signal processing.

Primary outcome measure

  • Bimodal benefit in percent correct scores for consonant perception with three signal processing conditions [ Time Frame: 24 weeks ]
