A Design for a Test Method and an Automatic Measurement Device of Hand-Held Directional High-Intensity Shield
Firstly,a test method of hand-held directional high-intensity shield is introduced,which is different from the test methods of traditional stationary high-intensity directional devices.The peak sound pressure level on the back and horizontal beam angle are added in this test method.Secondly,according to this method,an automatic test device is developed using a simulated robotic arm.Finally,an hand-held directional high-intensity shield is tested using this device.The test results show that this method and divice can be used to describe the sound field produced by hand-held directional high-intensity shield,and the impact on remote targets and the operator position can be evaluated.
