## What is Noise Tracker Pro?

"Noise Tracker Pro" is a unique sound meter application for mobile phones developed by
the noise experts from CSIR - National Environmental Engineering Research Institute
(NEERI), Nagpur, India, to give a more specific product or application through continuous
research and development efforts. "Noise Tracker Pro" is a handy, essential gadget,
highly reliable App, pre-calibrated measurements, and supports frequency weightings.
The "Noise Tracker Pro" App is a real-time noise monitoring application (noise meter, dB
meter) dedicated to evaluating noise levels in the surrounding environment as
professional sound meter performs. This App will use the phone microphone to measure
environmental noise levels dB (decibels) and display noise levels on the mobile screen.
This smartphone application is a handy tool for the students, professionals, and the
general public to know the extent of noise levels in their surrounding environment. The
accuracy level may change with the change in the make and model of the smartphone.
Hence it is always recommended to calibrate the application with an already calibrated
SPL meter to improve the accuracy of measurement by adjusting the microphone
sensitivity
Features:
1. Performance best fits with calibrated SPL meter
2. Very efficient saved record data management
3. Indicates decibel by digital gauge
4. Quick response on sound level changes
5. Standard fast time weighting
6. Compare the recorded noise level with popular international reference standards
7.  A- Frequency weighting filter
8. Measure Equivalent A-weighted continuous sound level (LAeq),
9. I/3 Octave in graphical and tabular format
10. Display SPL, LAeq, Average , Minimum and Maximum decibel values
11. Measure noise descriptors L 10 , L 50 & L 90
12. Display Elapsed time of decibel
13. Create the geotagged map for the saved history data
14. Handy custom Calibration for high precision and accuracy
15. Data storage in the phone
16. One can share the saved and recorded data across multiple platforms such as Gmail,
WhatsApp, etc.

Recommendations for the 'best' measurement:
1. The smart microphone should not be kept hidden during measurement.
2. The smartphone should not be in the pocket but should be held on hand while noise
measurements.
3. Don’t make a noise on the back of the smartphone while monitoring noise.
4. Keep safe distances 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 Apple
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.

## Key features

- Real-time noise monitoring (dB meter)
- Frequency weighting filters (A-weighting)
- Measure LAeq, L10, L50, L90
- Geotagged noise level maps
- Custom calibration for accuracy
- Data sharing across platforms
- Comparison with international standards


## Frequently asked questions about Noise Tracker Pro

### What is Noise Tracker Pro?

Noise Tracker Pro is a mobile application that functions as a sound meter to measure environmental noise levels in decibels (dB) using your phone's microphone. It provides real-time monitoring and analysis of ambient sound.

### How accurate is Noise Tracker Pro?

The accuracy of Noise Tracker Pro can vary depending on the smartphone model. For improved precision, it is recommended to calibrate the application with an already calibrated SPL meter by adjusting the microphone sensitivity.

### Can Noise Tracker Pro measure very loud sounds?

Most smartphone microphones have limitations and may not accurately recognize very loud sounds over approximately 90 dB. For precise measurements of extremely loud noises, a professional sound level meter is recommended.

### Does Noise Tracker Pro have ads?

No, Noise Tracker Pro does not contain advertisements. It is a free application developed by noise experts from CSIR - NEERI.

### What kind of noise data does Noise Tracker Pro provide?

Noise Tracker Pro can measure and display various noise descriptors including SPL, LAeq (Equivalent A-weighted continuous sound level), Average, Minimum, Maximum decibel values, and noise descriptors like L10, L50, and L90.

### Can I save and share my noise measurements with Noise Tracker Pro?

Yes, Noise Tracker Pro allows for efficient management and storage of recorded data on your phone. You can also share saved and recorded data across multiple platforms such as Gmail and WhatsApp.

### What are the best practices for using Noise Tracker Pro for accurate measurements?

For best measurement results, ensure the smartphone microphone is not hidden, hold the phone in hand rather than in a pocket, avoid making noise behind the smartphone during monitoring, and maintain a safe distance from the noise source.

### What devices is Noise Tracker Pro available on?

Noise Tracker Pro is currently supported on iPhone and iPod devices. It is rated for ages 4 and up.
