Primary | Comparison of How Four Models of Personal Listening Devices Improve Word Understanding in Noise | Improvement in performance on speech perception task using the Nuheara IQ Buds, Tweak Focus, Bose Hearphones, or the Sound World Solutions CS 50+ personal listening devices, measured by percentage of words accurately recalled in noise with device minus percentage recalled without device. Positive values indicate improvement in performance. | One 2-hour lab session | |
Secondary | Difference in Self-rated Listening Effort | Effect of listening devices on subjective listening effort, measured by rating on ten-point scale (10 = greatest amount of effort) after task performed with device minus rating after task performed without device. Lower scores indicate less listening effort; negative values indicate reduction in effort with device. | One 2-hour session |
