Application Of Effective Noise Control Strategies In Speech Perception Testing Rooms, Samuel H. Underwood

Theses/Capstones/Creative Projects

This project examines experimental methodologies, common test practices, and identifies relevant acoustic metrics to determine effective noise control parameters and strategies for implementation in a new speech perception testing room in Lincoln, Nebraska. The nature of speech perception testing demands that the experiment facility be as quiet and non-disruptive as possible to ensure that auditory stimuli is not interfered with. Influences of ambient acoustic conditions, like background noise and reverberation time, interfere with speech perception testing by introducing new variables that are often difficult to account for if left uncontrolled. A room-in-room chamber (sound booth) is often a best-case practice …
