Effects Of Time Varying Background Noise Conditions On Human Perception And Performance, Andrew H. Hathaway
Effects Of Time Varying Background Noise Conditions On Human Perception And Performance, Andrew H. Hathaway
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
This thesis was designed to study the effects of changing noise conditions on human perception and performance. In two phases, participants were exposed to a number of noise conditions and their performance on an arithmetic task involving short-term memory was monitored and their subjective perception of noise conditions was collected via questionnaires.
In the first phase, participants were tested while being subjected to RC-29(H) and RC-47(RV) conditions created by broadband noise fluctuating on different time intervals, resembling the changing noise conditions potentially found in modern HVAC systems. These intervals varied from two minutes to ten minutes. Results show a significant …
