Select a place in your neighborhood where you go daily or quite often.
Measure the noise level in decibels using either the noise app in your digital device or a sound probe twice (around 8am and 8pm) a day for 7 days in a row. (Refer to the instructions that came with your app or noise level probe.)
Record your measurements. If you are using one of the probes that support direct data transfer to GlobalLab, you do not have to write down your measurements. Your data is stored at GlobalLab. Please refer to the Working with Probes section on the Support page
Take a photo of the source of the loudest noise if possible.
Determine or estimate the distance from the measuring site to the source of the noise (in meters*).
Fill in and submit a Report Form for each measurement. You will have a total of 14 Report Forms (two for each day of the week).
Try to precisely locate the marker on the map (Question 1 of the Report Form) for each of the 14 Report Forms you will submit. Remember, you can zoom in on the map.

- Where are the noisiest places?
- What are the sources of these noises? - How would you assess noise pollution in your neighborhood? (read more on noise pollution here).
Take part in discussions pertaining to the present investigation on the GlobalLab forum.
*Why report distances in meters?
To compare data, all measurements must be reported in common units. How can we compare distances if some data are in feet and others in meters? We use meters simply because meters are the standard in most of the world.
Units of measurement must be standardized in all collaborative investigations and projects.
Do not go near the sources of the loud noise because it may negatively affect your hearing.
