This is a very quick overview of the B&K (Bruel & Kjoer) sound meter. Model 2209. These are the meters we use for sound testing when firing suppressors. These are one of the few meters that can accurately measure the gun shot impulse accurately. Most meters cannot measure it properly and will not give you an accurate reading. This meter runs in the 5000$ range. A B&K 4231 calibration device was also used.
