摘要
为了最大程度地减少摩托车噪声测试中存在的测试及数据处理误差问题,将近场声全息和声强检测法结合起来,能够在工况下进行噪声检测,有效屏蔽了环境噪声,使得噪声测量更加准确有效。
in order to minimize the error problem in the noise detection of motorcycle combining the acoustic holography with acoustic intensity method,can be make a accurate measurement in the working condition of noise detection.
