Product News for Decibel Testing
Less Than Lethal (LTL) devices Munitions Testing diversionary device. Parameters have been established to evaluate the need of hearing protection from impulse, transient sound waves. These shock pressure waves are measured using piezo-electric pressure transducers and the reading is converted into decibel sound measurements. Fire susceptibility. 12 gauge and 40 mm projectile characterization. Flash bang and diversionary characterization. We use a custom high-speed data acquisition system to control several of our tests. The system consists of 16... (read more)
Ballistic Testing E-Labs has an extensive background in the development and testing of Less Than Lethal (LTL) devices. We were the first to develop a measuring system to capture blunt force or impulse of a round in real time. The Ballistic Impulse Measuring System (BIMS) developed by E-Labs was used on USMC programs to evaluate LTL rounds and compare impulses on a one to one basis. (read more)

The derivation for the constant in the above equation comes from the decibel equivalent of the factor of 1000 used to convert W to mW and vice...
