The psychological benefits of interacting with nature have been discussed for well over a century (e.g., Olmsted, 1993), with research over the past few decades assessing how interactions with nature specifically may benefit cognition and cognitive development (e.g., Bratman, Hamilton, & Daily, 2012). These results provide initial evidence that brief experiences with natural sounds can improve directed attention functioning in a single experimental session. Natural sounds did not differentially change positive or negative affect, despite these sounds being aesthetically preferred to urban sounds. Urban soundscapes did not systematically affect performance either adversely or beneficially. Relative to participants who were exposed to urban soundscapes, we observed significant improvements in cognitive performance for individuals exposed to nature. Participants completed these cognitive measures and an affective questionnaire before and after listening to and aesthetically judging either natural or urban soundscapes (between-participants). To assess directed attention, we created a composite measure consisting of a backward digit span task and a dual n-back task. In the present experiment, we assessed whether nature-related cognitive benefits extended to auditory presentations of nature, a topic that has been understudied. 24 bits : DVD-Audio, which can support up to 24-bit audio.Attention restoration theory (ART) posits that stimuli found in nature may restore directed attention functioning by reducing demands on the endogenous attention system. 96,000 Hz : DVD-Audio, some LPCM DVD tracks, BD-ROM (Blu-ray Disc) audio tracks, HD DVD (High-Definition DVD) audio tracks.īit depth: 16 Bits (?) More : In digital audio, bit depth describes the number of bits of information recorded for each sample. 48,000 Hz : The standard used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on. Sampling Rate: 48,000 Hz (?) Search : Defines the number of samples per seconds taken from a continuous signal to make a discrete signal. Par exemple : Un brossage de dent imité avec une brosse à ongle. Un " Foley" à été enregistré en studio, avec des astuces de bruiteurs. Par exemple : Un brossage de dent sans dentifrice. Un son " Idealized" à été enregistré en condition réel mais en ne gardant cherchant à coller au plus près de l'idée qu'on se fait de ce son. Par exemple : Un brossage de dent avec dentifrice. Realism: Real (?) Un son " Real" à été enregistré en condition réel. It can not, for example, be used to sound an image taken outdoors. There is sometimes a little wind, some rumors, etc.Ī " indoor" sound usually contains a strong reverb. Used, for example, in virtual reality.Ĭonditions: Outdoor (?) A " studio" sound has been recorded in a reverb-free place.Īn " outdoor" sound contains disruptive elements. ![]() ![]() ![]() Ambisonic : aims to create a multi-channel sound space. Stereophonic : Is a method of sound reproduction that creates an illusion of directionality and audible perspective. Typically there is only one microphone, one loudspeaker. Click to display the full UCS list.Ĭhannels: Monophonic (?) - Monophonic : Is single-channel. ![]() This sound library meets the UCS 8.2 categorization. It provides consistency in a filename structure to make naming and categorizing easier for anyone who maintains their own personal or professional library. This is a list of fixed and consistent categories for classifying sound effects. UCS Category: Animals / Insect ( ANMLInsc) (?) The UCS, for "Universal Category System", is a public domain initiative by Tim Nielsen, Justin Drury and Kai Paquin, among others.
