FAQ AZ 8925 Auto-Range Sound Meter Q1: What does "Auto Ranging" mean on the AZ 8925? A1: Auto Ranging means the device automatically adjusts its internal sensitivity to match the sound level it hears. You don't have to manually switch between ranges (like 40-90dB or 80-130dB); the meter handles the transition for you instantly.
Q2: When should I use A-weighting (dBA)? A2: Use A-weighting for almost all general noise environmental measurements. It is the standard for: *OSHA workplace safety compliance. *Environmental noise complaints (e.g., loud neighbors or traffic). *General office or residential sound levels.
Q3: When should I use C-weighting (dBC)? A3: Use C-weighting when you are dealing with loud, low-frequency noises. It is ideal for: *Measuring the "thump" of a subwoofer or heavy machinery. *Checking peak sound pressure levels in industrial settings. *Evaluating the effectiveness of earplugs or soundproofing materials. |
