【Abstract】 In application of the acoustical theory, a method of noise prediction and measures of reducing noise in highway tunnel is investigated in combination with the engineering of a expressway tunnel. A prediction model, the methods of determination of the parameters, the calculating example and several comparative programs of reducing noise are given.更多还原
