Objective:
This study measured the performance of normal-hearing listeners on the Repeat-Recall Test (RRT) in two noise types (2-talker babble [2TBN] and continuous speech-shaped noise [SSN]) by two noise azimuths (0° and 180°) configurations at signal-to-noise ratios (SNRs) of 0, 5, 10, and 15 dB and quiet.
Design:
Within-subject repeated measures.
Study Sample:
Twenty-one listeners with normal hearing who also passed cognitive screening were tested in the sound-field with the speech stimulus presented from 0° at 75 dB SPL in 4 noise configurations. The order of SNRs, noise configurations, and RRT topic conditions was counterbalanced across listeners.
Results:
Analysis revealed that repeat scores were significantly better for 2TBN, for noise at 180°, and for high context (HC) sentences. Recall performance was significantly better for SSN and HC sentences. Listening effort ratings were higher for SSN and for noise front condition at SNR ≤ 10 dB. The 2TBN noise was tolerated longer than SSN. Performance on all measures improved with SNRs.
Conclusions:
These data showed performance differences among noise configurations and provided a preliminary basis for comparison with hearing-impaired listeners' performance on the RRT.

Auditory Perception
Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...
Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...
