The Hioki FT3432 sound level meter is used in noise management by facilitating the measurement of noise in factories and schools, near machinery, etc., to ensure a more comfortable environment. Small enough to fit in a pocket and weighing just 105 g, the instrument measures sound level, equivalent continuous sound level, sound exposure level, maximum sound level, and C-weighted peak sound level.
