Compression may refer to:
[edit] Physical science
- Physical compression, the result of the subjection of a material to compressive stress
- Compression member, a class of structural elements, of which a column is the most common specific example
- Compressibility, the reciprocal of the bulk modulus (typically for solids)
- Gas compression, raising the pressure and reducing the volume of gases
- Compression ratio, a number that predicts the performance of any internal-combustion engine
- Compressibility, a measure of volume change resulting from pressure (typically for fluids)
- Compression (geology), a system of forces that tend to decrease the volume of or shorten rocks
[edit] Information science
- Data compression, the process of encoding information using fewer bits
- Dynamic range compression in audio recording and mastering, usually artificially introduced gain compression to make the audio louder on the same volume setting
[edit] Other sciences and technologies
- Gain compression, in electronic amplifiers, a result of device non-linearity
- Audio level compression, in deliberate audio processing, to increase perceived loudness
- Compression (functional analysis), in mathematics
- Compression bandage, designed to reduce the flow of blood. it also means to compress
- Brain Compression, A very deadly condition where pressure is exerted on the brain by internal bleeding
- compression (phonetics), running syllables together in informal speech.
- Compression (zoology) when an animal, or part of an animal, is shorter or narrower compared with other animals in the same group; e.g. the body of a lizard may be compressed (flattened) so it can better fit into crevices under rocks
