On today's military battlefield, efficient communication is essential for reducing risk for the soldier and ensuring mission success. For soldiers, the ability to communicate clearly in high noise environments while protecting their hearing and still retaining situational awareness, is a tactical advantage and can be a life saver. Soldiers in the field often experience very high noise levels that can impede mission critical communication and damage the soldier’s hearing. Hearing impairment is the most common injury of soldiers returning from active duty. Combine this with the risk of short term hearing damage due to explosions and the risk of mission failure increases. Rooth physical and electronic systems provide certified hearing protection solution to meet the needs of demanding users in high noise environments.
