Speech Perception in Bimodal Hearing

Completed · Not applicable

Conditions studied: Hearing Loss, Sensorineural

In brief

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.
