Comparison of How Four Models of Personal Listening Devices Improve Word Understanding in Noise Primary · One 2-hour lab session

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.

Group	Value	95% CI
Tweak Focus	1.65	± 6.40
CS50+	0.85	± 7.01
IQ Buds	7.35	± 6.03
Bose	10.24	± 8.23

Difference in Self-rated Listening Effort Secondary · One 2-hour session

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.

Group	Value	95% CI
Tweak Focus	-1.4	± 1.26
CS50+	-1.4	± 1.84
IQ Buds	-0.9	± 1.29
Bose	-1.8	± 1.81

Sponsor's own description

This study will measure the performance of three personal amplification devices when used by middle-aged adults. Speech understanding will be assessed with two different types of background noises at three different input levels.
