结局指标
主要结局
Percent of Words Correctly Recognized in Noisy Conditions with Clinical NR
时间窗: Up to Year 2 (Completion of Experiment 2)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in noisy listening conditions while using a clinical NR algorithm.
Percent of Words Correctly Recognized in Quiet Conditions with Clinical NR
时间窗: Up to Year 2 (Completion of Experiment 2)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in quite listening conditions while using a clinical NR algorithm.
Percent of Words Correctly Recognized with Very Low-Computation SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 4)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized with the Very Low-Computation SEDA NR, which is designed to have a reasonable ESTOI value with minimal computational requirements.
Visual Analogue Scale (VAS) Rating of SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 1.2)
Participants will be presented with two buttons: one button will play a sample with SEDA NR and the other will play a sample without SEDA NR. Listeners will report which sample was preferable by clicking on a horizontal visual analog scale (VAS). VAS ratings will be scored on a scale of -10 to 10 where positive numbers indicate a preference for SEDA NR and negative numbers indicate a preference for not using SEDA NR. The magnitude of the absolute value of the score indicates the strength of the preference.
Percent of Words Correctly Recognized with no SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 4)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized without SEDA NR.
Percent of Words Correctly Recognized in Noisy Conditions with SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 1.1)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in noisy listening conditions while using the SEDA Noise Reduction (NR) algorithm.
Percent of Words Correctly Recognized in Quiet Conditions with SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 1.1)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in quiet listening conditions while using the SEDA NR.
Percent of Words Correctly Recognized in Quiet Conditions without NR
时间窗: Up to Year 2 (Completion of Experiment 1.1)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in quiet listening conditions with SEDA NR.
Percent of Words Correctly Recognized in Noisy Conditions without NR
时间窗: Up to Year 2 (Completion of Experiment 1.1)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized in noisy listening conditions without SEDA NR.
Percent of Words Correctly Recognized with Standard SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 4)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized with Standard SEDA NR.
Percent of Words Correctly Recognized with Low-Computation SEDA NR
时间窗: Up to Year 2 (Completion of Experiment 4)
Participants will listen to sentences and repeat all the words they heard. This outcome measures the percent of words correctly recognized with the Low-Computation SEDA NR, which is designed to have minimal computation while maintaining an Extended Short-Time Objective Intelligibility Predictor (ESTOI) value similar to the "standard" SEDA implementation
