Examples of audio (audible sounds)

• Human generated speech/sounds (live)



• Human generated speech/sounds (live) • Human generated speech/sounds (recorded)



• Human generated speech/sounds (live) • Human generated speech/sounds (recorded)• Music (live and recorded)



• Human generated speech/sounds (live) • Human generated speech/sounds (recorded)• Music (live and recorded)• Noise


1. If a tree falls in a forest and no one is around to hear it, does it make a sound?


Just because you speak (especially as a teacher/instructor), it does not mean that you have been heard.

(Just think of all the times you have asked a question - only to get a blank stare !!!)


2. Do you hear what I hear ?

It is the line from a Christmas carol, but it can also point to the nature of hearing.


Hearing : (definition)

the act of perceiving sound by the ear. If you are not hearing-impaired, hearing simply happens.


Hearing VS Listening

You consciously choose to listen.

It requires concentration to process for meaning.

Why use audio in learning?

1. Dual-coding theory• Learners receive graphics and text

through the same channel (visually).• Text and graphics can compete with each

other.



1. Dual-coding theory• A complex diagram with a text description

of its elements next to it can overload for the learner.



1. Dual-coding theory• Audio comes through a different channel (as in,

your ear). Think about removing the text, or paring it back. Then use audio to narrate the elements in your graphic.

2. Audio is more personal* than text• Audio carries a lot more personality, tone

and conviction than text does.



2. Audio is more personal* than text• An expert with a great example to share,

or a story to tell can bring it to life.


Things to consider for audio in learning

1. Learners can read faster than you can speak.



2. When you have text and audio carrying an identical message, the media will fight with each other and the learner will lose. (Closed-captioning and audio on !!!!)



3. Major “faux pas” when using audio: • Read the bullets that are on the screen,

ask learner to click next, repeat until learner passes out.



4. Keep audio in e-learning of high quality• Keep it to 30 seconds if you can • Keep it sounding natural- no odd delays or edits • Keep the volume consistent between clips


Tools for using audio

1. Computer-based• Sound Recorder (PC)• SimpleSound (Mac)
