Soundscapes are audio recordings or performances that attempt to present the multiple, overlapping, sounds one might hear in specific acoustic environments, either exclusively or in combination with musical composition / performance. Acoustic environments include all the sounds (human, mechanical, environmental) within a particular area (built or natural) as they are modified by the environment. Soundwalks promote listening to a soundscape by walking to sound sources. Sound maps plot sound sources at specific locations and promote listening to targeted sounds within a soundscape. Information and listening opportunities are provided. Transects sample particular or characteristic sounds along a path through a space or place, which, when combined, provide a mix or collage of the soundscape.
Soundscapes feature the sonic components of acoustic environments and their perception by humans. Soundscapes might represent real or imagined places: forests, oceans, cities, space, or other worlds. The sounds might be natural—animal vocalizations, weather, other—human activities—music, sound design, conversation, work or mechanical sounds. Soundscapes are sometimes called sonic geographies.
R. Murray Schafer developed the term soundscape as part of founding the World Soundscape Project at Simon Fraser University, Burnaby, British Columbia, Canada, in the late 1960s. He argued that a great deal can be learned from studying the social dimensions of sound. His work continues to influence soundscape artists and people active in the interdisciplinary field of acoustic ecology. 
For example, Steven Feld says that soundscapes are not separate from human invention / interaction.
Soundscapes, no less than landscapes, are not just physical exteriors, spatially surrounding or apart from actors who attend to them as a way of making their place in and through the world. Soundscapes are invested with significance by those whose bodies and lives resonate with them in social time and space. Like landscapes, they are as much psychical as physical phenomena, as much cultural constructs as materials ones. . . . Sound both emanates from and penetrates bodies; this reciprocity of reflection and absorption is a creative means of orientation—one that tunes bodies to places and times through their sounding potential. Hearing and producing sound are thus embodied competencies that situate actors and their agency in particular historical worlds. These competencies contribute to their distinct and shared ways of being human; they contribute to possibilities for and realizations of authority, understanding, reflexivity, compassion, and identity (Feld 2003, 226).
Schafer speaks of soundscapes as fluid fields, potentially immersive aural environments, changed with the introduction of each new sound. Describing soundscapes, Schafer used the term "hi-fi" to denote an acoustic environment where one can listen to sounds clearly without masking or crowding. Conversely, "lo-fi" describes a dense and noisy acoustic environment, like a city. In either type of acoustic environment, Schafer notes the presence of keynote sounds (background sounds, like wind, traffic, or water), sound signals (predominate foreground sounds that should be listened to carefully), and sound marks (sounds unique or particular to the context). In this example nature / environment soundscape, the sound mark is the sound of the woodpecker repeated throughout.

Rather than nature or environmental sounds, soundscapes might focus on mechanical sounds. This example uses field recordings of antique, gas-powered tractors and farm machinery at a county fair.
"Symphony for Antique Tractors"
John F. Barber
Soundscapes might combine environmental and human sounds as in this example, also composed from field recordings at a county fair.
"Voice of the Fair"
John F. Barber
Soundscapes might also combine environmental, human, and mechanical sounds, as in this example, recording at a pedestrian crossing on Bay Street, Savannah, Georgia.
"Bay Street Crossing"

Imaginary places, with different sound sources, might also promote soundscapes. This example imagines sounds that might be heard in the operating room of an alien spacecraft.
"Alien Operating Room"

Another imaginary place is inside the Internet. This soundscape, "Internet Soundscape," imagines the sounds of electronic commerce. Learn more and listen.
Michael Vincent says we can hear literary, musical events in soundscapes. For example, restaurant soundscapes can be heard as "spoken word choral performances." The hushed tones of conversation prior to the start of a movie are "akin to the tuning of an orchestra before an evening performance" (Vincent 2008, 59). Building on that idea, I created this soundscape for Dene Grigar's work of participatory electronic literature, Curlew, a story about a man's struggles with the ocean, the elements, and the gods.
John F. Barber
We might also imagine soundscapes as improbable combinations of sounds in order to provide an aural narrative.
"Soundscape 1: Remix"
John F. Barber
Finally, Garbriele Proy says the effect of listening to a soundscape should be immersion in its sounds, as well as one's memories of similar aural environments (Proy 2013). In this regard, soundscapes might help us understand information not normally presented as sound. The Listen to Wikipedia website is a sonification of recent changes to Wikipedia. Bells indicate additions. String plucks subtractions. Pitch changes according to the size of the edit. The larger the edit, the deeper the note. The result is a soundscape of the constant editing of Wikipedia content.

New York Society for Acoustic Ecology
This project describes itself as a container in which to hold many different processes and projects focusing on the city's shifting sonic environment and temporal, physical, and cultural contexts. Among these projects are "Sound Seeker," a Google map-based interface for listening to the sounds of New York. Clicking icons on a map plays the recorded sound, and shows the address, date, time of day, author, and other information regarding the recording; and "City in a Sidewalk," where participants are invited to navigate a provided soundwalk, or create one of their own. Using an online forum, participants can exchange personal narratives, photographs, drawings, sound recordings, environmental data, historical details, maps, and other information about their walks.
WFAE: World Forum for Acoustic Ecology
An international organization engaged in multi-disciplinary study of the social, cultural and ecological aspects of the sonic environment. Part of their mission is "protecting and preserving existing natural soundscapes and time and places of quiet."
Soundwalks are excursions in acoustic environments for the purpose of listening to the sounds of that environment's soundscape. Generally, one walks within a defined area experiencing the sounds to be heard there. The term and practice of soundwalks evolved from the World Soundscape Project, founded by Canadian composer R. Murray Schafer in the late 1960s-early 1970s at Simon Fraser University, Vancouver, Canada. Notable practitioners include Claudia Westerkamp (Westerkamp 2014), Andra McCartney (McCartney 2014), and Viv Corringham (Corringham 2016).
Soundwalks can be designed for individual or group listening. They can cover a wide or small area, even targeted portions of a soundscape. Soundwalks that address portions or targeted portions of a soundscape are often called "location-based" or "locative." See examples by Jeremy Hight and others.
No matter the approach, the objective of soundwalks is to provide active participation with a soundscape by reactivating one's sense of hearing and encouraging active listening. Soundwalks encourage one to listen carefully and critically to sounds and consider their contribution to the acoustic environment.

34 North 118 West
Jeremy Hight, Jeff Knowlton, Naomi Spellman
2003, Los Angeles, California
Combining audio narrative, digital media, and GPS technology, "34 North 118 West" delivers an interactive story centered around the railroad freight depot situated at 34 North latitude and 118 West longitude in downtown Los Angeles, California, early in the 20th century. Participants walked throughout the area with a tablet computer equipped with a GPS card and headphones. Physical maps are also available. GPS tracks one's position in the neighborhood and triggers audio-visual narratives when entering hot spots created by Hight, Knowlton, and Spellman. The streets, the buildings, the ghosts of former residents, all provide fragments that, taken together, provide a deep and rich narrative of this place. By evoking these multiple narratives, many lost or forgotten, participants uncovered the hidden history of this once thriving part of downtown Los Angeles. "34 North 118 West," with its combination of urban infrastructure and storytelling is a pioneering locative narrative. Learn more.
2003 - present, various locations
Subtitled "Electromagnetic Investigations in the City," this ongoing project, begun in 2003 by Berlin-based sound artist Christina Kubisch, uses specially-built headphones to receive electromagnetic signals from the city environment and convert them into sound. Kubisch maps a given territory, noting hot spots (ATM machines, security systems, electronic cash registers, subway systems, etc.) where the signals are particularly strong or interesting. Participants, wearing headphones, undertake an auditory walk through the invisible network of electromagnetic information. Electrical walks have been offered in Germany, England, France, Ireland, Japan, Latvia, Sweden, Switzerland, Slovakia, Spain, Taiwan, and the United States. I created this example from samples of Kubisch's electrical walks including a light advertisement in Sendai, Japan; a magnetic field in the Science Museum, London, England; a subway in Taipei, Taiwan; a decorative electrical flame, at an unknown location; and Gare de l'Est, Paris, France.
Audio stories set in San Francisco are the basis for this contemporary locative narrative. The samples sound promising. The app sounds tempting.

A Guide to Getting Lost
This sound walk, created by international sound artist Jennie Savage, uses audio recorded over five continents, including in Moroccan souks, Indian streets, tropical beaches, a London Market, bustling European towns, and a snowy Canadian city. Use her soundwalk in your acoustic environment as a guide, turning right and left at points narrated by Savage. Or follow your own route as a Wanderer, Idler, or Drifter. Either way, walkers are challenged to see familiar geography afresh, to give themselves up to walking without purpose and to experience serendipitous moments when sound from the recording appears to sync up with "real life" and real time events.

The Missing Voice
1999, Whitechapel Library, London
Subtitled "(Case Study B): An Audio Walk," this CD-based audio walk by Canadian sound artist Janet Cardiff, begins in the crime section of the Whitechapel Library. Cardiff's breathy voice, coming from the CD, listened to with a portable player and headphones, leads one on a physical and psychological tour of Spitalfields and the City of London. The tour ends at the Liverpool Street Station. One has to find their way back to the library. Part urban guide, part historical account, part detective fiction, part film noir, recorded in binaural stereo, the piece provides an uncanny surround sound context. This, along with the merging of sound effects and real street noises and Cardiff's stream-of-consciousness descriptions of simultaneous scenarios reinforce the isolation, the anonymity, the invisibility, of the individual in a large city. Searching for connection, for relationships, the solitary person often creates drama, imagines her life the soundtrack for a movie experienced by a walk through the set rather than a theatre viewing. The listener's hears hear one thing. Her brain thinks another. Cardiff: "Sound allows people to use their imagination more than film or video." The thinking voice mixes with other voices, removing one from the story. The listener/viewer, with a delicious lack of control or authority over the outcome, becomes a participant in the experience. Schizophrenia? Or, audio drama? Headphones provide the best listening experience.
The Whitechapel Library closed in 2005 and was absorbed by Whitechapel Gallery. One can still download Cardiff's The Missing Voice in three parts and begin the walk just outside the gallery. Information about "The Missing Voice" at the Janet Cardiff and George Bures website.

Sound maps plot sound sources at specific locations within a soundscape, often on a digital map. By providing routes for soundwalks and information about what might be heard at specific locations along them, sound maps promote active participation with the soundscape and encourage participants to listen carefully in order to make critical judgements about the contributions the mapped sounds make to the complete soundscape.
Using computer-based mapping and audio file encoding technologies, sound maps provide access to the sound elements of particular locations within a soundscape. Thus, sound maps can make soundscapes publicly available in a comprehensive fashion as digital databases. Sound maps can also be created collaboratively by users recording site specific soundscapes and uploading them into the sound map.
