About WideNoise
Check noise levels
With WideNoise you can monitor the noise levels around you, everywhere you go. You can also check the online map to see the average sound level of the area around you. Do you live in a "sleeping cat area" or in a more noisy "rock concert area"? Are you able to find the most silent spot in the city? And that park is really as silent as you think?
Our noise detections calibration
We've used a sound meter (±2dB@114dB) to calibrate the microphone against pink noise, that is a form of noise similar to the sounds that our ears perceive the best. After that, we had to compensate for the limits of the physical mic, which is calibrated to filter the human voice against the ambient sound. The result is accurate within the device's hardware limits, but while it's a great tool to have an indication about perceived noise, it shouldn't be used for dB readings that require high accuracy.
Noise is pollution as well
We live every day surrounded by all kinds of sound around us. We are accustomed to this background noise, but in the end we feel relieved when, maybe in a park, that stressful noise disappears. WideNoise helps you better understand the soundscape around you.
Twitter and Facebook
Noise pollution is something we often overlook. That's why we added the ability to use Twitter and Facebook to raise awareness about it! Check the stream of people detecting noise all around the world here or the map.
Open source
WideNoise since version 3.0 and thanks to the EveryAware project is now open source. You can find it on GitHub.
