Axiom Home Page Forums General Discussion Technical Questions C-weighted , A-weighted ???

Choosing the 'C' weighting will make the meter respond more-or-less uniformly over the frequency range from 32 - 10,000 Hz, and the 'A' weighting will make the meter more sensitive to frequencies in the range 500-10,000 Hz. The response switch allows for changing the speed of the meter's response from 'SLOW' to 'FAST'. A slow response setting will make the meter less sensitive to rapid changes in sound level and can be used for measuring average pressure levels. The 'fast' setting is more useful when peak sound levels are being measured since in this mode, the meter will respond to very rapid changes in pressure level.
