Table 1.
Silent Cities dataset description.
| Name | Description | Type | Number of files |
|---|---|---|---|
| Collection of acoustic recordings | Preprocessed 10-second audio files from soundscape recordings collected for each site (compressed in tar.gz archives) | FLAC | 16,252,373 |
| Glossary | Definitions of table elements | csv | 1 |
| dB | List of readable files uploaded by the contributors and their dB level (archived in a single zip file) | csv | 317 |
| Site | Information about each site including contributors’ description about the recorder (e.g. type and serial number), the location (e.g. description of the surrounding area, city), and the description of the containment measures in place at the time of deployment. Also contains the metadata describing the landscape (e.g. population density, climate) corresponding to the cities of the dataset as well as the extracted information about the protocol used (e.g. type, sampling rate, file duration), and the amount of data collected | csv | 1 |
| ConfinementLevels | For each country and date covered by the acoustic collection, displays information about the levels of “stay-at-home requirements" according to the dataset built by the University of Oxford | csv | 1 |
| SunMoon | Information about the sun and moon azimuth and altitude for the dates and times covered by the Silent Cities dataset, with a 10-second increment, for each city (197 csv files in a zip file) | csv | 197 |
| AcousticMeasurements | List of preprocessed 10-second acoustic files and associated calculations of acoustic indices and categories of automatic sound event (all csv files compressed in a single zip file) | csv | 317 |
| AcousticMeasurements_nospeech | Same as AcousticMeasurements but only for recordings without speech (all csv.gz files in a single zip file) | csv.gz | 317 |
| ManualIdentification | Sound event identification made by contributors on a subsample of the original 1-min recordings | csv | 1 |
| AverageCompleteTable | For each unique site at a unique date and a unique hour, averaged values of acoustic indices and automated event recognition categories. This table also includes the corresponding Site, SunMoon, and ConfinementLevels information. Finally, given the original recording date and time in UTC+0 and knowing the associated timezone, a local date and time information was calculated | csv | 1 |
| AverageCompleteTable_nospeech | Same as AverageCompleteTable but the averaged values are only calculated on speech-filtered subsample of the acoustic collection | csv | 1 |
