Sound pressure level meters, first introduced in early 2003, allow musicians, sound contractors and others to measure SPL in decibels (dB). A decibel is defined as the unit for measuring relative loudness of a sound. We have expanded our line from one check mate SPL meter to four products in the category. We have sold thousands of units to working musicians, DJs, police departments, sound contractors and racetracks.
