text: The operation of a detonation gun is a very loud process due to the multiple explosions occurring in the chamber per second. This could cause damage to operators hearing if in close proximity to the D-gun. As a result, detonation spraying should be performed within a sound proof room and no one should be present in the room during operation. Also operators should wear ear protection (such as ear muffs and/or ear plugs) while working with a D-gun.
