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.
