Study Notes
Sound and Acoustics
- Sound is a vibration that travels as an acoustic wave through mediums like gases, liquids, and solids.
- Acoustics is an interdisciplinary science focusing on mechanical waves in various states of matter, including sound, ultrasound, and infrasound.
Physics of Sound
- Sound propagates as longitudinal waves in air and water, while solids can carry both longitudinal and transverse waves.
- Longitudinal waves involve vibrations parallel to wave direction, while transverse waves have vibrations perpendicular to the wave direction.
Waves: Nature and Characteristics
- Vibrations are disturbances that move back and forth within a medium.
- Waves transfer energy through matter or space, characterized by properties such as amplitude, wavelength, frequency, duration, intensity, pitch, and quality.
Basic Characteristics of Sound
- Amplitude: The height of a wave, related to its loudness.
- Wavelength: The distance between successive crests of a wave, affecting frequency.
- Frequency: The number of waves passing a point in a given time, determining pitch.
- Duration: The length of time a sound is heard.
- Quality: The timbre or color of a sound, distinguishing different instruments or voices.
- Intensity: The power of the sound per unit area.
Audio Technology Components
- A sound card is essential for audio input and output in devices.
- Audio file formats can be categorized into lossless compressed, free open formats, and proprietary formats which affect sound quality and compatibility.
- Codec: A method for encoding and decoding audio files, crucial for compressing data.
Audio Editing Applications
- Software tools are available for audio editing in studios and by professional journalists.
- Editing can include normalizing audio levels for broadcasting and preparing files for portable devices.
- System requirements vary: compatible with Windows XP and later, Mac OS X 10.2 or higher, and can operate under Linux with WINE.
Five Elements of a Great Sounding System
- Essential components of a high-quality audio system include sound cards, proper file formats, and effective editing software to enhance audio experiences.
