You may have used maps or Google Maps when navigating in places you are not unfamiliar with. Has it occurred to you how very visual those maps are, that they are merely visual representation of areas? Have you imagined a different kind of maps that feature not the visual aspect of the environment but the auditory?
A sound map uses map to represent the soundscape or soundmark of locations. Its objective is to represent a specific environment using its soundscape as primary references as opposed to visual cues. Sound maps are created by associating landscape (streets in a city, train stations, stores, pathways, factories, oil pumps, etc.) and soundscapes. Sound maps do not have to be large in scale, nor do the sounds represented have to be symbolic. It can simply be a map representing the sonic environment of your home in which the tap water can be heard running in kitchen and washroom, the washing machine droning in the living room, while the television blasting in the bedroom.
Crowdsourcing is usually the method of collecting data for sound mapping. Since people perceive the same sonic environment differently, crowdsourcing allows participants to contribute each of their own responses and piece together a sound map with diversity. Considering that sound is transient in nature and that various types of sound can be heard over time at the same spot, crowdsourcing enables the development of a comprehensive and detailed sound map by listeners’ collective effort.
Sound maps are in many ways the most effective auditory archive of an environment. The creation of sound maps encourages people to visit a particular location in person in order to experience the actual sonic environment and afterwards chip in and share their own observations. Also, sound maps enable users to re-experience the environment with focus on its sonic elements. So if you want a certain sound replayed without having to drop by a certain place, you may refer to the sound map of the location which enables access of its soundscape at all times simply with your electronic devices
