Study Notes

Listening and Sound Perception

Listening skills can be developed through training, with sensitivity to sound varying among individuals.
Defined as perceiving sound with careful attention, analyzing qualities like style and interpretation.
New sonic experiences, regardless of their strangeness, contribute to deeper engagement with sound.
Personal reactions to sound can be influenced by one's mood and feelings.

Importance of Selective Hearing

People often develop selective hearing, filtering out sounds deemed interesting or useful.
Focusing on all sounds, not just the pleasing ones, enhances understanding and control over sound.

Environmental Factors in Sound

Various environmental elements shape sound perception, such as room shape, materials, air quality, etc.
Individual differences in hearing make it challenging to create universal standards for describing sound.

Describing Sound Qualities

Key controllable qualities of sound include intensity, duration, and timbre.
Common terminology for sound quality includes tone, volume, presence, and sustain, requiring further description.
Adjectives help articulate differences between high, mid, and low tones within sonic events.

Glossary of Sound Descriptions

Terms like airy, bassy, and bright describe specific sound characteristics, providing a vocabulary for sound analysis.
Warm, rich, and clean tones reflect desirable sound qualities across various contexts.
Low tones may be described as chesty or punchy, mid tones as strong or tinny, and high tones as crisp or airy.

Categories and Descriptions of Sound

Airy: Spacious quality, high-frequency clarity.
Bassy: Warmth in low frequencies, typically below 200 Hz.
Boxy: Resonation similar to sound trapped in a box.
Crisp: Clear high-frequency response contributing to clarity in cymbals.
Full: Strong fundamentals balanced with harmonics, providing richness to vocals and instruments.
Muddy: Lack of clarity, often due to weak harmonics or distortion.

Sound Quality Characteristics

Bright: High-frequency emphasis, strong harmonics.
Warm: Good bass with adequate harmonic levels.
Thin: Weak fundamentals relative to harmonics.
Smooth: Easy listening experience, without harshness or distortion.
Transparent: Clarity in sound, minimal distortion or noise.

Common Sound Issues

Boomy: Excessive bass, leading to muddled sound.
Muffled: Sounds lacking clarity, often resembling coverings.
Harsh: Excessive upper midrange frequencies causing discomfort.
Veiled: Sound with slight distortion, lacking transparency.

Overall Sound Experience

Adequate response in mid and high frequencies is essential to achieve a balanced auditory experience.
Understanding and using a comprehensive vocabulary for sound can enhance discussions about audio quality and sound perception.

Sound Characteristics

Sounds with a slow attack build gradually before reaching their peak amplitude, examples include a dog's warning growl, stepping on a dry leaf, or slowly tearing paper.
A thunderclap serves as an example of a sound with a long attack, taking approximately five seconds for the buildup before the loud clap occurs.

Decay

Decay refers to the reduction in amplitude of a sound once the vibrating force has stopped, with the time it takes to diminish to silence termed decay time.
Indoors, sounds exhibit little decay due to absorbency, while outdoors sounds will have longer decay with echoes.
The beginning of a sound is termed the "head," while the end is referred to as the "tail."

Sustain

Sustain measures the duration a sound remains at its peak before it begins to fade out, influenced by the energy from the source vibrations.

Release

Release is the final phase where a sound's amplitude gradually fades over time.

Envelope of Sound

The envelope of sound is defined by four components: Attack, Decay, Sustain, and Release (ADSR).

Attack

Attack characterizes how a sound is initiated, divided into fast and slow types.
Fast attack examples include gunshots, slaps, and door slams, while slow attack examples take longer to reach their peak.

Speed and Playback

Adjusting playback speed alters sound properties; doubling speed changes an explosion's sound to resemble a gunshot.
PAL speed-up results in films running 4% faster when played back, affecting sound perception.

Loudness

Human sensitivity peaks in the midrange frequency of 250 Hz to 5000 Hz.
Perceptual coloring affects loudness, where midrange sounds are perceived as louder when played at the same decibel level as bass sounds.
Loudness also correlates with perceived distance; louder sounds are often perceived as closer.

Rhythm

Rhythm encompasses beat, pulse, tempo, and accent patterns, present in music, speech, sound effects, and images.
"Mickey Mousing" is a technique where sound closely synchronizes with visual movement, notably used in Disney animations.

Components of Sound

Key components influencing sound perception include Pitch, Timbre, Harmonics, Loudness, Rhythm, Attack, Decay, Sustain, Release, and Speed.

Frequency and Wavelength

Sound waves that humans can hear lie between 16 Hz and 20,000 Hz.
Frequencies below 16 Hz are infrasonic, while those above 20 kHz are ultrasonic.
Frequency is inversely related to period; higher frequency results in a shorter period.
Velocity of sound relates to frequency and wavelength via the formula: V = n × λ.

Conclusion

Sound plays a crucial role in communication and perception, with distinct characteristics determining its nature and impact.
