Manufactured by Larson Davis, a division of PCB Piezotronicsbased in USA
Quantitative measurements of sound pressure levels generated by firearms with and without suppression devices and silencers. Many firearm examiners are tasked with determining whether installation of a suppressor or silencer on a firearm results in a “perceptible” reduction of the sound pressure level of a gun. The Larson ...
