À propos de l'application

The Noise Tracker Pro App is a real-time A-weighted noise monitoring application dedicated to evaluating the surrounding noise environment. This app will use the phone microphone to measure environmental noise levels (decibels) and display noise levels on the mobile screen. With this app, you can efficiently measure the equivalent sound pressure levels dB (A) emerging from various sources and compare them with the many popular international standards for compliance. Simple operation and easy for easy handling.

Features:
- Performance best fits with calibrated SPL meter
- Very efficient saved record data management
- Indicates decibel by digital gauge
- Quick response on sound level changes
- Standard fast time weighting
- Compare the recorded noise level with popular international reference standards
- A- Frequency weighting filter
- Measure Equivalent A-weighted continuous sound level (LAeq),
- 1/3 Octave in graphical and tabular format
- Display SPL, LAeq, Average, Minimum and Maximum decibel values
- Measure noise descriptors L10, L50 & L90
- Display Elapsed time of decibel
- Create the geotagged map for the saved history data
- Handy custom Calibration for high precision and accuracy
- Data storage in the phone
- One can share the saved and recorded data across multiple platforms such as Gmail, WhatsApp, etc.

Recommendations for the 'best' measurement:
- The smart microphone should not be kept hidden during measurement.
- The smartphone should not be in the pocket but should be held on hand while noise measurements.
- Don’t make a noise on the back of the smartphone while monitoring noise.
- Keep a safe distance from the source during noise monitoring; otherwise, it may harm you.

**Notes
This tool is not a professional device to measure decibels. Microphones in most android devices are aligned to the human voice. The smartphone microphone device limits the maximum values due to which Very loud sounds (over ~90 dB) may not be recognized by most of the devices. So please use it as just auxiliary tools. If you need more accurate dB values, we recommend an actual sound level meter for noise measurements.
