2. Images Maps Videos All More G o o g l e WHAT IS AUDITORY DISPLAY? Auditory display is the use of speech or non-speech sound to present information . It is where information is presented to you via your ears. back proceed

3. Images Maps Videos All More G o o g l e HOW WE HEAR SOUND? back proceed

4. Images Maps Videos All More G o o g l e HOW WE HEAR SOUND? STEP 1: Sound transfers into the ear canal and causes the eardrum to move . STEP 2: The eardrum will vibrate with vibrates with the different sounds . STEP 3: These sound vibrations make their way through the ossicles to the cochlea . STEP 4: Sound vibrations make the fluid in the cochlea travel like ocean waves STEP 5: Movement of fluid in turn makes the hair cells. The auditory nerve picks up any neural signals created by the hair cells. Hair cells at one end of the cochlea transfer low pitch sound information and hair cells at the opposite end transfer high pitch sound information. STEP 6: The auditory nerve moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”. back proceed

5. Images Maps Videos All More G o o g l e TYPES OF AUDITORY DISPLAY AUDIFICATION- A direct translation of a data waveform to the audible domain for purposes of monitoring and comprehension. Example : Seismogram back proceed

6. Images Maps Videos All More G o o g l e TYPES OF AUDITORY DISPLAY SONIFICATION- The use of data to control a sound parameter for the purpose of monitoring and analysis of data. Example : Morse Code back proceed

7. Images Maps Videos All More G o o g l e TYPES OF SONIFICATION Auditory Icons- are natural sounds whose natural associations are used to map with the data. Example : OS X’s Trash can sound back proceed

8. Images Maps Videos All More G o o g l e TYPES OF SONIFICATION Earcons- are abstract, musical tones used in structured combinations to create sound messages. Example : Sound for Different Weather Conditions back proceed

9. Images Maps Videos All More G o o g l e TYPES OF AUDITORY DISPLAY SPEARCONS- are a combination of speech and earcons in that they consist of speeding up a spoken phrase (very recognizable) until it is not recognized as speech (more like an icon). back proceed SPEECH + EARCONS = SPEARCONS

10. Images Maps Videos All More G o o g l e EXAMPLES OF AUDITORY DISPLAY Auditory information displays are commonplace in the speech we generate and hear, the radios/music we listen to, the TV's we watch, etc . F requently used for alerting, warnings, and alarms-situations in which the information occurs randomly and requires immediate attention. back proceed

11. FIRE ALARM Information: There is a smoke or fire condition in your building or place .

12. RADIO ANNOUNCEMENT Information: About something that has happened or that will happen.

13. TELEPHONE RING Information: Someone is calling.

14. Images Maps Videos All More G o o g l e WHERE DID “HELLO” CAME FROM? Hello is the common greeting we use when picking up the phone, but it wasn’t always that way. Alexander Graham Bell, the inventor of the telephone, suggested using “ahoy” when answering the phone. It was actually Thomas Edison who suggested using “ hello”. back proceed

15. Images Maps Videos All More G o o g l e The Word “Telephone” Was Used Before The Telephone Existed The word “telephone” was first used in 1828 by a man named Francois Sudre to describe his invention, which was a musical signaling device. Later on, the term was also applied to the phone as we know it. back proceed

16. NOTIFICATION SOUNDS Information: You have unread or snoozed notifications, you have a message or someone sent you a message.

17. AMBULANCE SIREN SOUND Information: There is someone going to the hospital or to the house of a patient so give them space to go their.

18. WHISTLE SOUND Information: Someone is attracting an attention or signalling.

19. CAR HORN/ BEEP SOUND Information: Signals or warn others of a vehicle's approach or presence. Signals the driver about any electrical malfunction in the car .

20. Images Maps Videos All More G o o g l e GENERAL PRINCIPLES Compatibility - Make use of pre-existing stimulus-response relationships which may be natural, learned, or population stereotypes. ( 1) Orienting reflex - reflex to turn to the source of a sound (stimulus) ( 2) Learned - Examples are sirens which are learned to be associated with an emergency back proceed

21. Images Maps Videos All More G o o g l e GENERAL PRINCIPLES Approximation- Complex messages should be presented in two stage signals : ( 1) Attention Demanding Signal - to capture attention . (2) Designation Signal - with precise message information . back proceed

22. Images Maps Videos All More G o o g l e GENERAL PRINCIPLES Dissociability - Auditory signal must be discernible from other noise, especially multiple auditory signals back proceed

23. Images Maps Videos All More G o o g l e GENERAL PRINCIPLES Parsimony - Messages should be as short as possible . back proceed

24. Images Maps Videos All More G o o g l e GENERAL PRINCIPLES Invariance - Same signal or message should designate the same information in all situations to avoid confusion like that between "priority" and "emergency" information. back proceed PRIORITY EMERGENCY

25. Images Maps Videos All More G o o g l e WHEN TO USE THE AUDITORY VERSUS VISUAL FORM OF PRESENTATION back proceed auditory display visual display

26. Images Maps Videos All More G o o g l e WHEN TO USE THE AUDITORY VERSUS VISUAL FORM OF PRESENTATION back proceed auditory display visual display Use auditory presentation if: The message is simple. The message is short. The message will not be referred to later. The message deals with events in time. The message calls for immediate action. The visual system of the person is overburdened. The receiving location is too bright or dark adaptation integrity is necessary. The person's job requires him or her to move about continually.   Use visual presentation if: The message is complex. The message is long. The message will be referred to later. The message deals with location in space. The message does not call for immediate action. The auditory system of the person is overburdened. The receiving location is too noisy. The person's job allows him or her to remain in one position.  

27. Images Maps Videos All More G o o g l e USING AUDITORY DISPLAY EFFECTIVELY Use frequencies between 200 - 5 Khz. Preferred range is between 500 and 3 Khz the most sensitive range for hearing. Use frequencies below 1000 Hz when the signal has to travel more than 1000 feet. Use frequencies below 500 Hz when the signal has to pass through partitions or "bend around" obstacles. Use modulated signal (1 - 8 beeps/ sec, warble 1 - 3/sec) Use signals with frequencies different from background noise to avoid masking. For choice situations, use moderate intensity easily discriminable frequency or amplitude signals (but not too many). Where possible use separate auditory warning system which is different from other auditory signals. back proceed
