This app was build in collaboration with The Ohio State University's Department of Speech and Hearing Science. It is a citizen science project to measure the sound levels in the cities around us. Anyone can contribute to the project, however, we require that you come and get your device calibrated before uploading any measurements to the data set.
Features:
- Accurate measurement of A-weighted sound pressure levels in dB(A)
- Calibration specific to each device
- Contribute measurements to the dataset
Required permissions:
- Location, so that the measurements correspond to an accurate location within cities
- Record Audio, to be able to measure the sound levels
Feature updates
- Added data point filtering on the main map page
Stability fixes.
- Fixed crashing issue after cancelling a recording and starting a new one.
