### Dataset Summary

TUT Urban Acoustic Scenes 2018 development dataset consists of 10-seconds audio segments from 10 acoustic scenes:

    Airport - airport
    Indoor shopping mall - shopping_mall
    Metro station - metro_station
    Pedestrian street - street_pedestrian
    Public square - public_square
    Street with medium level of traffic - street_traffic
    Travelling by a tram - tram
    Travelling by a bus - bus

    Urban park - park

Each acoustic scene has 864 segments (144 minutes of audio). The dataset contains in total 24 hours of audio.

The dataset was collected in Finland by Tampere University of Technology between 02/2018 - 03/2018. 
The data collection has received funding from the European Research Council under the ERC Grant Agreement 637422 EVERYSOUND.

## Dataset Structure

### Data Instances

```
{
  'scene_label': 'airport',
  'identifier': 'barcelona-0',
  'source_label': 'a',
  'audio': {'path': '/data/airport-barcelona-0-0-a.wav'
           'array': array([-1.91628933e-04, -1.18494034e-04, -1.87635422e-04, ...,

       'sampling_rate': 48000}
}

```

### Data Fields



- `scene_label`: acoustic scene label from the 10 class set,
- `identifier`: city-location id 'barcelona-0',
- `source_label: device id, for this dataset is always the same 'a',


Filenames of the dataset have the following pattern:

[scene label]-[city]-[location id]-[segment id]-[device id].wav

### Data Splits

A suggested training/test partitioning of the development set is provided in order to make results reported with this dataset uniform. The partitioning is done such that the segments recorded at the same location are included into the same subset - either training or testing. The partitioning is done aiming for a 70/30 ratio between the number of segments in training and test subsets while taking into account recording locations, and selecting the closest available option.

## Dataset Creation

### Source Data

#### Initial Data Collection and Normalization

The dataset was recorded in six large European cities: Barcelona, Helsinki, London, Paris, Stockholm, and Vienna. For all acoustic scenes, audio was captured in multiple locations: different streets, different parks, different shopping malls. In each location, multiple 2-3 minute long audio recordings were captured in a few slightly different positions (2-4) within the selected location. Collected audio material was cut into segments of 10 seconds length. 

The equipment used for recording consists of a binaural [Soundman OKM II Klassik/studio A3](http://www.soundman.de/en/products/) electret in-ear microphone and a [Zoom F8](https://www.zoom.co.jp/products/handy-recorder/zoom-f8-multitrack-field-recorder) audio recorder using 48 kHz sampling rate and 24 bit resolution. During the recording, the microphones were worn by the recording person in the ears, and head movement was kept to minimum.




### Annotations

#### Annotation process

Post-processing of the recorded audio involves aspects related to privacy of recorded individuals, and possible errors in the recording process. Some interferences from mobile phones are audible, but are considered part of real-world recording process.


#### Who are the annotators?


* Ronal Bejarano Rodriguez
* Eemi Fagerlund
* Aino Koskimies
* Toni Heittola


### Personal and Sensitive Information

The material was screened for content, and segments containing close microphone conversation were eliminated.
