Level vs Ojo PR

Level is a fast, honest sound-level meter for iPhone. A big live decibel reading, with Leq, Min, L90, L10, Peak, and elapsed time alongside it — show up to four, arranged the way you want. It tells you when the sound is louder than the mic can measure. A reference generator and calibrated-mic support are there for speaker work or true SPL. One clean instrument, not a busy suite. FEATURES - Big decibel reading — A/C/Z weighting, Fast (125 ms) or Slow (1 s) response - Six readings, up to four on screen: Leq (energy-average), Min, L90 (background level — exceeded 90% of the time), L10 (exceeded 10% of the time), Peak (true instantaneous peak), and Time (how long you've been measuring). Always computed; show only what you need - Arrange the readings yourself — hold one on the meter and drag it, or reorder in Settings. On iPhone Duo's open display, all six show - Overload flag — "Current · OVER" and a tick on the meter while the sound is louder than the mic can measure; Peak stays marked for the rest of the measurement. Tap either to see what it means - Peak-hold "Max" — a marker holds the loudest moment; tap the meter to start a new measurement - Control bar — play, the mic and output in use, and the signal, together at the bottom of the screen - Reference signals: pink noise, white noise, ten octave tones (31.5 Hz–16 kHz), level-matched. 1 kHz tone pairs with a 94 dB calibrator - Play any output — iPhone speaker, AirPlay, Bluetooth, or USB — while the meter keeps reading - Calibrated-mic support: Dayton iMM-6C, miniDSP UMIK-1/UMIK-2/EARS, Behringer ECM8000, REW. Frequency correction plus a true-SPL anchor from the file's 1 kHz sensitivity - Set to 94 dB — fit a calibrator over the mic, tap once, and Level trims itself to the tone. Each mic keeps its own offset - Share card — current reading, your readings as arranged, and the level bar - Fits iPhone Duo — closed, open, and open held wide - Full VoiceOver support - No account, no analytics, no third-party SDKs, no in-app purchases, no network connections HOW IT WORKS Open Level, allow the microphone, and read the room. Turn on up to four readings in Settings → Readings to see them beside the live number; hold one on the meter to move it. Tap the meter to reset Max and every reading and start a new measurement — Time starts over too. If the sound is louder than the mic can measure, Level says so: OVER appears beside the live number, and Peak stays marked until you reset. Tap the mark to see what it means. For speaker work, the control bar has it all: play sends the reference signal — pink noise for level-setting, white noise for tweeters, an octave tone for room modes, or the 1 kHz tone against a 94 dB calibrator — and the mic, output, and signal buttons switch each in a tap. With the built-in mic, readings are approximate but honest and well-behaved. A calibrated USB mic and its cal file give true SPL. Either way, Level is a measurement tool, not a certified Type 1/2 instrument. GREAT FOR - Checking if a room, party, nursery, or workspace is too loud - Home theater/hi-fi — matching channels, setting levels, dialing in a subwoofer - Car audio — matching and balancing components - Live-sound hobbyists and DIY speaker builders - Anyone who wants an honest number without a pro suite PRIVACY Audio is measured live only — never recorded, written to disk, or transmitted. No account, no analytics, no in-app purchases, no network connection at all. QUICK START 1. Open Level, allow the microphone 2. Read the big number (A-weighted by default) 3. Settings → Readings: turn on up to four of Leq/Min/L90/L10/Peak/Time; hold one on the meter to move it 4. Tap the meter to reset Max and every reading 5. For speaker work: tap play in the control bar; the buttons beside it switch mic, output, and signal IMPORTANT Level is a general-purpose meter, not a certified Type 1/Type 2 instrument. Built-in mic readings are approximate; a calibrated USB mic with a cal file gives true SPL.

The barrio has eyes. Ojo PR is Puerto Rico's app where neighbours share what is happening on their street — power and water outages, flooding, road closures and safety incidents — on a real-time community map. Ojo PR is not an emergency service and does not dispatch help. It is not connected to 9-1-1 or to any agency. If there is an emergency, call 9-1-1. POWER AND WATER OUTAGES No power?
