Decibels Sound Level Meter vs FilterFit

Sound Level Meter is an iOS tool for everyday environmental noise measurement—see levels in the field, keep a log, and share a polished Pro report when you need one. Features • Live A-weighted sound level with Fast / Slow time weighting • Session stats: energy-style average (LAeq) and peak (LAmax-style) • Acoustic calibration offset to align with a reference source • History with custom titles and optional location notes • Export CSV / JSON and Pro PDF measurement reports • Education: hearing & decibels, typical noise level ranges Good for Home and office background noise, street/neighbor logging, DIY checks around renovations or equipment, quick reference notes and sharing. Disclaimer Readings are estimated from the phone microphone and software. Results vary with device, mic sensitivity, handling, wind, reflections, and calibration. Outputs are for personal reference, logging, and sharing only—not legal metrology, certified lab reports, or compliance determinations. Use a calibrated standard sound level meter and qualified professionals when precision matters.

FilterFit — Find the right filter for your car in seconds. Stop guessing part numbers and cross-referencing charts. FilterFit matches your exact vehicle to the oil, engine air, cabin air, fuel, and transmission filters it takes — plus wiper blade sizes — all in one place.

Matches are engine-aware and year-accurate, so a V6 and a 4-cylinder of the same model get their correct, different filters — not a one-size-fits-all guess.
