Why do we need to measure noise?

Sound level meters are commonly used to measure noise levels in people's environments and to ensure people stay within safe noise limits and protect people from hearing damage/loss.

What scenarios are sound level meters usually used for?

Sound level meters are often used for measuring community or environmental noise; Use for measuring noise produced by machinery in industries; Use for calibrating audio equipment at concerts or for personal reasons.

What is the difference between A Frequency Weighting and C Frequency Weighting?

The A-weighting adjusts the sound pressure level readings to reflect the sensitivity of the human ear and is used for hearing damage risk measurements. The C-Weighting is used for Peak measurements and also in some entertainment noise measurements.

What is the difference MAX/MIN Value between A-Weighting and C-Weighting?

MAX/MIN Value of A-Weighting is Lmax/Lmin (the highest and lowest values measured by the sound level meter over a given period of time.); MAX/MIN Value of C-Weighting is Lpeak (the max/min value of the absolute instantaneous sound pressure).
