Why doesn’t the TS-501B show 0 dB in a quiet environment?

The TS-501B measures from 30–130 dB and does not start at 0 dB. When sound levels are below 30 dB, it displays “UL” (Under Limit). In a quiet environment, it reads between 30 and 45 dB.

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).
