    <subfield code="a">&lt;p&gt;This is a corpus of 100 sound scenes of 45s each representing urban sound environments, including:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;6 scenes recorded in Paris,&lt;/li&gt;
	&lt;li&gt;19 scenes simulated using simScene (https://bitbucket.org/mlagrange/simscene) to replicate recorded scenarios, including the 6 recordings in this corpus,&lt;/li&gt;
	&lt;li&gt;75 scenes simulated using simScene with diverse new scenarios, containing traffic, human voices and bird sources.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The base audio files used for simulation are obtained from Freesound (https://freesound.org) and LibriSpeech (http://www.openslr.org/12).&lt;/p&gt;

&lt;p&gt;This corpus has been evaluated by a panel of participants in a listening experiment, with assessments on the following 0-10 Likert scales:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&lt;strong&gt;Pleasantness&lt;/strong&gt;: Unpleasant - Pleasant,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Liveliness&lt;/strong&gt;: Inert, amorphous - Lively, eventful,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Overall loudness&lt;/strong&gt;: Quiet - Noisy,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Interest&lt;/strong&gt;: Boring, uninteresting - Stimulating, interesting,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Calmness&lt;/strong&gt;: Agitated, chaotic - Calm, peaceful,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Sound level of passing vehicles&lt;/strong&gt;: Very low - Very high,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Time of presence of traffic&lt;/strong&gt;: Never - Continuously,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Time of presence of voices&lt;/strong&gt;: Never - Continuously,&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Time of presence of birds&lt;/strong&gt;: Never - Continuously.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Assessments from 23 subjects are available for the 6 recorded and 19 simulated scenes, and from 7 to 8 subjects for the 75 simulated scenes.&lt;/p&gt;

&lt;p&gt;The contents of this dataset are as follow:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;&lt;em&gt;assessments&lt;/em&gt;: contains evaluations by 23 subjects of perceptual scales on the corpus

	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;sXX&lt;/em&gt;: Folder corresponding to participant XX

		&lt;ul&gt;
			&lt;li&gt;&lt;em&gt;Pt_.txt&lt;/em&gt;: Contains assessments. Each line corresponds to one scene, columns correspond to (resp.) scene number (see audio_list.txt for correspondance), pleasantness, liveliness, overall loudness, interest, calmness, sound level of passing vehicles, time of presence of traffic, human voices, bird sources.&lt;/li&gt;
		&lt;/ul&gt;
		&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;audio&lt;/em&gt;
	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;rec&lt;/em&gt;: contains the 6 recorded 45s scenes&lt;/li&gt;
		&lt;li&gt;&lt;em&gt;rep&lt;/em&gt;: contains the 19 replicated 45s scenes, with separated tracks for source contributions&lt;/li&gt;
		&lt;li&gt;&lt;em&gt;sim&lt;/em&gt;: contains the 75 simulated 45s scenes, with separated tracks for source contributions&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;audio_list.txt&lt;/em&gt;: list of audio files in the corpus, line ordering corresponds to numbers in the first column of assessments&lt;/li&gt;
	&lt;li&gt;&lt;em&gt;rep_exp.mat&lt;/em&gt;, &lt;em&gt;sim_exp.mat&lt;/em&gt;: Additional information about the corpus, with playback Leq and physical estimations of the perceptual time of presence of sources for each scene.&lt;/li&gt;
