Noise Meter – dB Sound Level

[ Accurate and smart noise measurement! ]
- Noise Meter is a practical app that precisely analyzes surrounding sounds through your smartphone and reports them in decibel (dB) values.
- When you are curious about the noise in your daily life, when you are concerned about safety in a noisy environment, and when you need a quiet space—now check the noise with your own eyes!


[ Main functions and features ]
- Accurate noise measurement
Using the smartphone microphone, it detects surrounding noise in real time and converts it into an accurate decibel value through a precise algorithm.
You can easily measure various noise levels, from quiet spaces like libraries to noisy environments like construction sites.
- Provides minimum / maximum / average decibels
Automatically records minimum, maximum, and average values during measurement, allowing you to see noise fluctuations at a glance.
This is especially useful for users who need long-term noise analysis.
- Measurement date and location record
You can save the date, time, and GPS-based address information of the noise measurement to keep an accurate record.
Use it for work, field reports, and daily life records.
- Provides examples of noise levels by situation
Provides intuitive example explanations of the environments in which the currently measured decibel level corresponds, such as ‘library level’, ‘office’, ‘roadside’, ‘subway’, and ‘construction site’.
It helps you understand noise easily!
- Sensor calibration function
Microphone performance may vary depending on the smartphone device.
The calibration function helps you measure noise accurately for your device.
If you want to know the sound more accurately, be sure to use this function.
- Supports result saving and screen capture
You can record the measured noise results at any time by capturing an image or saving a file.
You can also share them or use them for analysis and reporting.


[ User Guide ]
- This app measures noise based on the built-in microphone of the smartphone, so errors may occur compared to professional noise meters.
- Please actively use the sensor calibration function provided to increase measurement accuracy.
- Depending on the measurement environment, it may be affected by external noise (wind, hand friction, etc.), so please measure in a static state if possible.


[ Noise Meter is recommended for these people! ]
- People who want a quiet space such as a reading room or office
- Managers who need to manage noise at construction sites or work sites
- Teachers who want to check the noise level of educational spaces such as schools and academies
- People who want to create a peaceful atmosphere such as yoga or meditation
- Users who want to analyze everyday noise and use it as data
