Comparison of PSAPs in Different Maskers

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.
