Sound Meter: dB Decibel

Turn your phone into a sound level meter. Measure noise around you in
decibels (dB) in real time, watch it move on a live graph, and see how
loud your surroundings really are.
MEASURE SOUND INSTANTLY
• Real-time decibel readings from your microphone
• Colour-coded dial that shifts green to red as noise rises
• Live 15-second graph of sound level over time
• Minimum, average and maximum dB for every session
KNOW WHAT THE NUMBERS MEAN
Built-in reference chart compares your reading to everyday sounds —
from breathing at 10 dB and conversation at 60 dB, up to busy traffic,
motorcycles, concerts and beyond.
WHY PEOPLE USE IT
• Check if your workplace, gym or classroom is too loud
• Measure noisy neighbours, traffic or construction
• Find the quietest room in your home or office
• Test how well soundproofing or headphones actually work
• Keep an eye on volumes that could damage your hearing
SIMPLE AND PRIVATE
No account. No setup. Audio is processed entirely on your device and is
never recorded, saved or uploaded.
Note: this app uses your phone's microphone, which is not a calibrated
measurement instrument. Readings are a close approximation and vary by
device. It is not a replacement for a professional sound level meter
for occupational or legal use.
