ANALYZING A COMMERCIAL Sound Perception from the aural to the psyche

Aural Perception: what & why we hear Psychoacoustics (meaning) Frequency (pitch) Amplitude & Direction (volume) Direction & Distance (panning) Timbre (sound, collection of sound)

Frequency (pitch) Range of hearing (2o-20,000 Hz or vibrations per second) Musical sound – regular vibration rate Noise / speech – irregular vibration Regular vibration rate Irregular vibration rate

Amplitude & Direction Sound loses energy when traveling (fades out) Levels on a channel can determine direction (left or right) Precedence effect – we can distinguish 1/10,000 second difference of a sound entering one ear then the other.

Direction & Distance The amount of time for sound to decrease from original level Spatial sense (reverberation), what type of room?

Timbre Harmonic series – mathematical relationship of the multiple frequency components of a single sound through time. Sound – what kind of sounds are you hearing. Single sound, ambient noise, a specific instrument? Layered Sounds Add More Interest And Illusion like this image. The same Image is repeated and expanded.

Analyze TV Commercial PLAY THE CLASS EXERCISE MOVIE WITHOUT AUDIO. Make some notes to the following questions. Narrative/Linear Structure: What happens in the commercial? How are the actions and events affecting the viewer? What is the story-line? Dialogue/Language: Do characters speak to one another? What devices are used to gain our attention or affection? Observe facial expressions, body language, and setting. Technical Matters: Lighting, cuts and shot selection are important. Are the images close-up, wide angle? Many quick cuts? How are things lighted? Signs, Symbols and Intertextual Devices: Signs and symbols that represent something that refers to a cultural norm like a religious icon. Intertextuality refers to interpret text in terms of another such as in a parody – based upon ridiculing a text (or idea). Are there any signs used to influence your perception? What kind of music do you expect to hear? PLAY THE CLASS EXERCISE MOVIE AGAIN WITH AUDIO. Make some notes to the following questions. Sound and Music: What kind of music is used? (Express in terms of language from Sound & Function powerpoint & all subsequent lectures such as literal/non-literal, energy, leitmotif, etc.). How does the music affect your group? Did your perception of the commercial purpose change with audio? How?
