研究概览
简要总结
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.
详细描述
Speech understanding will be measured both unaided and aided with three different models of Personal Amplification devices (PSAPs). Sentences will be played to the participant from a loudspeaker located in front. Different types of background sounds (noise and other sentences) will be played from loudspeakers located to the right and left of the participant. Participants will be instructed to repeat back the sentence coming from the front. They also will rate subjective effort at the end of each block of trials.

结局指标
主要结局
Comparison of How Four Models of Personal Listening Devices Improve Word Understanding in Noise
时间窗: 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.
