Sound Meter dB vs BarkAway

Sound Meter dB turns your phone into a decibel meter and noise detector: a live dB reading on a color-coded dial, from quiet teal to dangerous red, with a history graph, safe-exposure guidance, a night-long noise log, a hearing test and a frequency analyzer. Open it and it's already measuring: the party next door, the office air conditioning, the restaurant that "isn't that loud". Ten readings a second, time-weighted like a real sound level meter, and your music or podcast keeps playing. NEW: NIGHT MODE Leave the phone by the bed, plugged in, and go to sleep. Night mode learns how quiet your room is, then logs every noise above it: when, how long, how loud and what kind of sound. In the morning, a report: the whole night on one chart, every noise marked, the loudest called out, your longest quiet stretch. Made for noisy neighbors, traffic, a barking dog, or whatever wakes you at 3 AM. NEW: HOW HIGH CAN YOU HEAR? The highest pitch you can hear drops with age. A one-minute hearing test climbs through tones up to 20,000 Hz and shows which age group your ears match. Share it and see how your friends do. For fun, not a medical test. NEW: YOUR DAILY NOISE DOSE How much of today's safe sound allowance have you used? The meter adds up every measurement of the day against the NIOSH limit (85 dBA for 8 hours) and shows it as one percentage. NEW: FREQUENCY ANALYZER (PRO) Third-octave bands from 50 Hz to 16 kHz and the dominant tone, live, with its musical note. A guide shows what usually makes each part of the spectrum (rumble, hum, whine, hiss), and the analyzer flags electrical hum. Find the source, not just the level. NEW: PDF REPORTS AND A NOISE DIARY (PRO) Turn any session into a clean PDF: the chart, the average and the peaks, every noise event, the measurement settings. Or put weeks of nights into one noise diary, the way a landlord, an HOA or the council asks for it: every noise with its date, time, level and type, and room for your notes. MEASURES LIKE A REAL METER A-weighted readings (dBA), Fast or Slow response, and Leq, the energy average: the same maths as a sound level meter. The dial holds the session peak and turns red past 100 dB. Have a reference meter? Calibrate against it in Settings. EVERY READING, IN PLAIN WORDS 40 dB is a quiet library, 60 a conversation, 75 a vacuum cleaner, 95 power tools, 110 a rock concert. Following the NIOSH guideline, the app shows how long the current level is safe for and counts the time over 85 dB. EVERY SESSION, SAVED Measurements stay on your device with their timeline and loudest moments. Share one as an image, export it as CSV, or make it a PDF report. FOCUS MODE The reading as big as the screen, and the whole screen turns red when the room stays above your limit. Made for classrooms, workshops and venues. PRIVATE, AND WORKS OFFLINE Sound is analyzed on your device, as numbers. No recording is kept or uploaded, not even in Night mode. No account, no connection needed. THE HONEST PART Phone microphones are built for voice, not metrology, and every model hears a little differently. Readings are good estimates for awareness and comparisons, not a substitute for a certified Class 1 or Class 2 instrument. GOOD FOR - Documenting noisy neighbors, traffic and night-time noise - Checking noise at home, at work, in a classroom or workshop - Concerts and events: knowing when to give your ears a break - Finding the hum, whine or rumble in a room - Sleep and study rooms, nurseries and baby rooms FREE, WITH AN OPTIONAL PRO Sound Meter dB is free, supported by a small banner and an occasional ad when the app opens. Sound Meter dB Pro is a one-time purchase, not a subscription: it removes the ads and unlocks the frequency analyzer, the full event list in night reports, PDF reports and the noise diary. The meter, Night mode, the hearing test, history, sharing and everything else stay free for everyone. Privacy policy: https://noise.chinesepowered.com/privacy.html
