If you are new to decibels
Begin with the article on logarithmic scale basics, then skim the FAQ. Your goal is not to memorize formulas, but to get comfortable with ideas like "+3 dB is a doubling of power" and "+10 dB sounds roughly twice as loud."
If you care about hearing safety
Focus on the hearing‑safety and tinnitus pieces. Compare their examples to your own listening habits — commutes, workouts, rehearsals, and events — and note where your routine might push you into higher‑risk exposure time.
If you have a noise complaint
Start with the Noise Ordinance Guide to find your city's legal limits, then use the measurement guide to document your readings properly before contacting local authorities.
If you record or mix audio
Read the guides on room acoustics and soundproofing, then experiment with microphone placement while watching the meter. Small changes in position can have a bigger impact than many plug‑in tweaks.
