may allow offloading some visual workload to the auditory channel.

Auditory display

may be used in traditional alarms, in process
monitoring displays, in computer system interfaces, and even to present complex multivariate data

tend to elicit an alerting response, and can be detected more quickly than signals presented via other modalities.

Acoustic signals

two well-known successes. of uses of auditory signals

Geiger counter and sonar

Perfectly

establish a mapping between a sound and an intended meaning, with no intrinsic relationship existing.

Symbolic displays

is explicitly symbolic, as are most auditory warnings and alarms

contain an immediate and intrinsic relationship between the display dimension and the information that is being conveyed.

Analogic displays

Perfectly

families of event notifications (indicating, for example, that a computer file was opened); slightly more analogic auditory icons, which are event notifiers that also reflect the details
of the events

Perfectly

is a generic term including all intentional, nonspeech audio that is designed to transmit information between a system and a user.

Auditory display

refers to a sound that alerts a user and conveys information about an
event.

are usually categorical and symbolic in nature

alarms

Perfectly

indicates the use of sound for part or all of the display of system variables and other information, usually including information about the details of the objects involved or the underlying process.

Auditory interface

Perfectly

is the use of nonspeech audio to present data.

Sonification

Perfectly

is the transformation of data relations into
auditory relations, for the purpose of studying and interpreting the data.

Sonification

Perfectly

can be used as a supplement to other (usually visual) displays, as an equal part of a multimodal display, or certainly as a complete display on its own

Sound/ auditory displays

How well did you know this?

Not at all

Perfectly

recommended when multiple complex data sources need to be monitored or compared, and
when the information contains 3D aspects

Sound

Another downside to auditory displays in some cases which means that sounds are not continuously present for study and
comparison.

Absence of Persistence

Ensuring audibility without disrupting subsequent speech communication is the basic goal in this
situation.

Auditory alarms

The primary goal for an alarm

to alert, notify, time or status without disruption

may present information about the details of the event, by varying the sound parameters.

sophisticated alarms

recommends measuring the ambient noise levels during system operation, and plotting noise sound pressure level (SPL, measured in dB) against noise frequency (in Hz).

Patterson (1982, 1990)

The loudness of an alarm sound component at a given frequency should be set between ____ above the background noise at that frequency, but in no cases must it exceed ____ SPL

15 and 25 dB 90dB

is used increasingly in human–machine interfaces to communicate more information than simple (symbolic) alarms, but still not as much as (analogic) data sonification.

Sound

sonic additions to widgets such as scroll bars and menus can assist users in making selections and choices more effectively than visual only interface elements.

graphical user interface (GUI)

describes small “languages” that can be made up of patterns of two or three musical notes

“earcon”

use sounds that in some way represent the actual features of objects involved in actions.

auditory icons

make a sound appear to originate in a specific position in three-dimensional (3D) auditory space

spatialization of sound

an overwhelmingly visual medium, an increasingly important means of civics, communication and learning about the world

Social media

the standard of Web accessibility, and many parts of the Web-browsing experience can be made accessible through semantics

Text-to-speech

transform low-level image data, like color, hue, saturation, or brightness, into auditory parameters, like timbre, pitch, or volume

sensory substitution devices (SSDs)

was used to generate an automatic description of the image, list objects in the image (“tags”), identify any celebrities, and determine the coordinates and gender of any faces in the image.

Computer Vision system

used to link the coordinates of each face generated by the Computer Vision system with a value for seven emotion categories

Emotion system

used to determine the sentiment of the text in each post.

Text Analytics system

used to read text on images

Optical Character Recognition (OCR)

was used to speak the text of the user name, main post, and automatically generated image caption

speech

was used to signal the sentiment and impact using acoustic cues designed to communicate emotion

Sonification

composed of short auditory icons and longer “soundscapes” – was created from the high-level image content

auditory scenes

longer in duration and were used to represent recognized actions or environments in the scene

Soundscapes

Make use of pre-existing stimulus-response relationships which may be natural, learned, or population stereotypes.

Compatibility

is a basic reflex to turn to the source of a sound (stimulus), e.g. If you want an auditory sound as a warning for a pilot, don't put the speaker behind the person!

Orienting reflex

Examples are sirens which are learned to be associated with an emergency; higher frequency = high value like a tea kettle whistle.

Learned

Auditory signal that captures attention

Attention Demanding Signal

Auditory signal with precise message information

Designation Signal

Auditory signal must be discernible from other noise, especially multiple auditory signals, e.g. when several phones ring in an office it's difficult to tell which is ringing.

Dissociability

Messages should be as short as possible

Parsimony

Same signal or message should designate the same information in all situations to avoid confusion like that between "priority" and "emergency" information.

Invariance

establish intensity relative to ambient noise levels to avoid masking.

Signal/noise ratio

works best to attract attention by minimizing perceptual adaptation to monotones and increasing the detectability of the signal, e.g. Beep! Beep! Beep! is better than "Beeeeeeep"!

Variable Signal -

Auditory displays are especially useful for signaling alarms partially because noise will go around corners. "Yeows" and "Beeps" get a faster response time.
