Abstract
Noise walls are installed along highways to reduce highway traffic noise in adjacent communities. Based on installation or aging effects, some noise walls contain small gaps between panels. Applying traditional barrier insertion loss measurements comparing sections with and without
gaps may not be possible due to site conditions. For this study, barrier-adjacent sound levels were collected at gap locations and comparable reference (non-gap) locations to determine the gap effect immediately behind the barrier. Two methods are then applied to determine how these gap effects
translate to nearby communities. Both broadband and spectral sound levels are analyzed to determine that the effects of a small gap (up to 0.5 inches in height and 10 inches in length) can be up to 2 dB near the barrier but diminish rapidly with distance.

期刊介绍:
Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
