Lesson Audio Information 15 and Media Audio helps recall memories, enhance brain activity and stimulate the brain (Molineux, 2007). Audio media is very useful in developing the listening skills of students (especially for language learning). Audio media supports distance learning. Audio media helps in memorization (music, mnemonics, etc.). In digital just like the computer, audio is processed by converting the analog signal into a digital code using PCM (Phase change memory). Audio frequency (AF) is an electrical alternating current within the 20 to 20,000 hertz range that can be used to produce acoustic sound. What I Need to Know Learning objectives At the end of this lesson, you are expected to: 1. describe the different dimensions of audio information and media; 2. comprehend how audio information and media is/are formally and informally produced, organized, and disseminated; 3. evaluate the reliability and validity of audio information and media its/their sources using selection criteria; and 4. produces and evaluates a creative audio-based presentation using design principle and elements. What I Know Pretest Let’s see how much you know before we discuss the lesson Identify what type of storage media in a given pictures below. Write your answers in a separate sheet of paper. 21  What’s In Review In the previous lesson you have learned that visual materials, programs, applications and the like that teachers and students use to formulate new information to aid learning through the use, analysis, evaluation and production of visual images. And forty percent of people will respond better to visual information than plain text. Primary the purpose of visual information is to gain attention, create meaning, and facilitate retention. But before we proceed to the next topic, let’s try to evaluate how much you know about audio information media What’s New Activity 15.1 What you will do Write T if the statement is true and F if it is false. _____ 1. Tape is magnetic tape on which sound can be recorded _____ 2. M4A/AAC is a common format for consumer audio, as well as a standard of digital audio compression for the transfer and playback of music on most digital audio players _____ 3. Radio broadcast - live or recorded audio sent through radio waves to reach a wide audience ______4. WAV is a Microsoft audio file format standard for storing an audio bitstream on PCs. ______5. Internet cloud is a secondary storage devices for storing audio files. What is It Discussion Hearing is the act of perceiving sound by the ear, while listening requires concentration so that you brain processes meaning from words and sentences. Listening leads to learning. Source: https://open.lib.umn.edu/app/uploads/sites/189/2016/06/4.1.1.jpg 22 Benefits of Listening Listening should not be taken for granted. Before the invention of writing, people conveyed virtually all knowledge through some combination of showing and telling. Elders recited tribal histories to attentive audiences. Listeners received religious teachings enthusiastically. Myths, legends, folktales, and stories for entertainment survived only because audiences were eager to listen. Nowadays, however, you can gain information and entertainment through reading and electronic recordings rather than through real-time listening. What you will do Activity 15.2: Direction: Choose and encircle the correct answer from the given options (Hear or Listen to) 1. I can _____________ the baby crying. She must be hungry. HEAR LISTEN TO 2. Hey! _____ it’s that spooky sound again. HEAR LISTEN! 3. I can’t _____ you. My dad’s vacuuming. HEAR LISTEN TO 4. Can you _____ again? Did she say John or Jan? HEAR LISTEN 5.

I called out to grandma but she didn’t _____ me. She wasn’t wearing her hearing aid. HEAR LISTEN 23 Design Principles and Elements Characteristic and Purposes of Sound 1. Volume-intensity of a sound 2. Tone-the audible characteristic of a sound 3. Pitch-is how high or low a sound is 4. Loudness-refers to the magnitude of the sound heard Purposes of a Sound 1. Give instructions or information 2. Provide feedback 3. To personalize or customize Elements of the Sound Design 1. Dialogue- speech, conversation, voice-over 2. Sound Effects-any sound other than music or dialogue 3. Music-vocal or instrumental sounds (or both) combined in such a way as to produce beauty of form, harmony, and expression of emotion Principles of Sound Design 1. Mixing- the combination, balance and control of multiple sound elements 2. Pace-time control, editing, order of events (linear, non-linear or multi-linear) 3. Stereo imaging- Using left and right channel for depth. This refers to the aspect of sound recording and reproduction. 4. Transition-how you get from one segment or element to another Types of Transitions 1. Segue - one element stops, the next begins ("cut" in film). 2. Cross-fade - one element fades out, the next fades in, and they overlap on the way. 3. V-Fade - First element fades to inaudible before the second element begins. 4. Fade to Black - V-Fade with some silence between elements. 5. Effects. 6. Stereo Imaging - Using left and right channel for depth. 24  What’s More Enrichment What you will do Direction:Identify the different controls (knobs) in sound mixer.
