Brief Summary

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.

Conditions

Auditory Perception

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (1)

• Difference in Self-rated Listening Effort

  One 2-hour session
