|
Hertz |
It is a frequency unit that equals the repetition of a phenomenon whose period is a second |
|
|
Frequency |
It is the number of cycles that happen in a second |
|
|
Echolocation |
It is the location of an object through the reflection of the sound waves |
|
|
Infrasound |
It is a sound whose vibration frequency is lower than the one which can be perceived by the human ear |
|
|
Ultrasound |
It is the sound whose frequency of vibrations is superior to the highest limit perceived by the human ear |
|
|
Sound |
It is the sensation produced in the hearing organ by the vibrational movement of the bodies that is transmitted through an elastics means |
|
|
Elasticity |
It is the characteristic that a material has to recover its extension and shape when a force that deformed it stops being put on it |
|
|
Acoustics |
It is a branch of physics that studies the sound production, transmission, storing, perception and reproduction |
|
|
Transducer |
It is the equipment that transforms a type of energy into another one and may work as recipient or as a generator
|
|
|
Tuning fork |
It is a voice and instrument regulator that consists of a steel sheet folded as a hook with a foot, and when it is a hit, it presents 435 vibrations per second
|
|
|
Compression |
It is the effort that an object is subject to by the action of two opposing forces that tend to diminish its volume
|
|
|
Rarefaction |
It refers to making a gaseous body less dense
|
|
|
Cycle |
It is the complete sequence of a periodic vibration. It goes from rarefaction to compression
|
|
|
Period |
It is the period of time that happens in a cycle
|
|
|
Sound wave frequency |
|
|
|
Wavelength |
It is the distance that the sound goes over in a complete cycle of change in pressure and it is the physical measure of a cycle's length
|
|
|
Amplitude |
It is the distance between a balance point and the highest wave point |
|
|
Tone |
It is the subjective perception of frequency. There are high tones and low tones |
|
|
Decibel |
It is a measuring unit that compares the minimum that human can hear against the level we want to measure |
|
|
Absorption |
It is the process in which sound is absorbed by an object when crashing against it |
|
|
Reflection |
It is the quantity of acoustic energy that will change direction when it crashes against the edge of an object |
|
|
Refraction |
It is the change in direction of the sound wave due to a variation of the means of scattering
|
|
|
Bitrate |
It is the transmission rate. It refers to the number of bits that is transmitted in a unit of time, usually kilobits per second |
|
|
Codecs |
It means coder-decoder. It is a software that consists of an algorithm to compress and decompress video in real time. It use doesn't interfere with the playing speed. There are also codecs for audio files |
|
|
Wrappers |
It is the way of organizing information related to digital audio that is not part of the sound per se such as headlines
|
|
|
WAV |
Audio digital format normally not compressed of
|
|
|
AIFF |
Is an audio file format standard used for storing sound data for personal computers and other electronic audio devices

|
MP3 |
Is a standars technology and format for a sound sequence into a very small file
|
|
|
AAC |
Is an audio coding standard for lossy digital audio compression
|
|
|
MIDI |
It refers to the communication protocol that lets electronic instruments, synthesizers, computers and other devices to communicate among themselves
|
|
|
Audacity |
Informatics multiplatform free app used for audio recording and edition
|
|
|
Garage band |
Informatics app that allows the user to create musical pieces
|
|
|
Monaural sound |
Is an audio system in which audio signals are mixed and then routed through a single audio channel
|
|
|
Stereophonic sound |
Divides sounds across two channels, then the recorded sounds are mixed so that some elements are channeled to the left and others to the right
|
|
|
Surround sound |
Is a technique for enriching the sound reproduction quality of an audio source
|
|
|
Streaming |
It is the reproduction of audio |
