Ontology of Silence


The Ontology of Silence is a project by Andrew Hugill. Please spend some time investigating the site at www.silences.network to get an understanding of the project.

You are invited to contribute silences and to get involved in discussion via this blog page or contact me directly.

Future blog posts will update you about the project and include the most recent discussions. This is very much work in progress, so it is to be expected that these pages will evolve and change over the coming months and years.

Meanwhile…. ssshhhh!


If you wish to contribute, please upload a silence using the UPLOAD link below. If there is a problem with that method, please email me using the Contact Form.

Your silence could be a sound file, image file, text file, etc. Sound files will be recordings of silences. Image, text, and other similar files will evoke silence in some way. To understand how that might work, please read the ontology carefully.

Name uploaded files with your name and any title, separated by underscores, as in the following example: andrew_hugill_wry_silence.aif

Files may be in any format, but please try to achieve the best quality.

Uploading a file indicates that you are willing to make the contents available to the Ontology of Silence project. Files must therefore be free from any copyright restrictions.

Along with the silence itself, please also upload a text file with the same filename as the silence. The text file should contain a very brief description of the silence. Do include any relevant factual information such as: sound recordist, artist, writer, date, location, etc. Finally, indicate the Affect and Effect of the silence, from your perspective.



Ontology of Silence

Domain Concept

  • A silence is a duration containing no intentional sound.
  • An intentional sound is that sound which is intended to interrupt a silence.
    • Unintentional sounds may have local intentionality but are made without awareness of the silence.
      • A silence in a forest may include the singing of birds who make intentional sound but without awareness of the silence.
      • Two lovers falling silent as they gaze into one another’s eyes in a crowded restaurant sustain their mutual silence despite the many unintentional sounds around them until they are interrupted (perhaps by a waiter bringing a menu).
    • A person disrespectfully calling out as a rugby union player tees up a kick at goal intends to disrupt the silence.
      • The extent to which an interruption successfully breaks a silence is a matter of common agreement. In some instances, a silence is deemed to have continued despite an attempted interruption. In this case, the intentional sound becomes absorbed into the silence.
  • A duration may be specified or unspecified, but silence will always have a duration.
    • The limits of the duration of a silence are set by the intrusion of intentional sound.
      • A duration may be measured in seconds, minutes, hours, days, weeks, months, years, lifetimes, or eternities.
  • Silences may be Real or Ideal.
    • Real silence is full of sound.
      • Since “a complete absence of sound” (OED) is an ideal condition, there will always be some sound in a real silence.
  • A Real Silence is an experience which can be either recorded or unrecorded.
    • A recorded silence is not the same silence as that which was experienced, but is rather a new, mediated silence.
  • Recorded silences have a Recording Type, which refers to the conditions under which the recording was made.
    • An Accidental Recording is an unintended silence on a recording.
    • An Ambient Recording is a silence in a given space.
    • A Concert Recording is a silence in a musical concert.
    • A Field Recording is a silence recorded in a specified location.
    • A Personal Recording is a silence recorded by an individual for private use.
    • A Studio Recording is a controlled silence recorded in a studio situation.
  • An unrecorded silence is an actual experience that may be represented in any medium other than recorded sound or may not be represented at all.
    • The typology of unrecorded silences is: Image; Music; Verbal; Written; or Unrepresented.
      • Image Types of unrecorded silence represents silence in an image, that may be: a movie; a painting; a photograph; a sculpture; any other image.
      • Music Types of unrecorded silence include both silent pieces of music and music that otherwise attempts to represent silence. They may be either composition or performance.
      • Verbal Types of unrecorded silence represent the silence through spoken words.
      • Written Types of unrecorded silence may be either poetry or prose.
      • Unrepresented Types of unrecorded silence are silences that are experienced but not represented in any way. This type exists but is necessarily void.
  • An ideal silence can only be evoked, but not experienced.
    • An ideal silence is the one described by the dictionary definition of silence as: “a complete absence of sound” (OED, 2017).
      • The silence in a vacuum is ideal, because it cannot not be experienced by a human being, but only evoked.
      • The “silence of the grave” is similarly ideal, because it cannot be experienced but only evoked.
  • The evocations of ideal silence are: Gestural; Imagistic; Sonic; Verbal; Written; Unclassified.
    • A Gestural Evocation conveys the ideal silence through gesture.
    • An Imagistic Evocation conveys an ideal silence through image.
    • A Sonic Evocation conveys the ideal silence through sound.
    • A Verbal Evocation conveys the ideal silence through spoken words.
    • A Written Evocation conveys the ideal silence through written words.
    • An Unclassified Evocation uses some other means than gesture, image, sound, or words (written or spoken) to convey the ideal silence.
