The extremes between loud and soft All audio systems are limited on the low end by circuit and other noise, and on the high end by distortion The usable range in between is called the dynamic range of the system
the range between the maximum and minimum amount of input radiant energy that an instrument can measure
The dynamic range of a data converter (ADC and DAC) is the range of signal amplitudes it can process effectively The minimum signal usually is the point where parameters such as SNR are 0dB (for example, signal power equals noise power) and the maximum signal is either the data converter's full-scale input or the point where distortions become an unacceptable large factor
The difference between the loudest and quietest signal levels in a system In an audio device, usually the difference between the maximum output level and the residual noise floor In a digital system, the available dynamic range is determined by the data resolution, about 6 dB per digital bit Hence, a 16-bit system theoretically provides a 96 dB dynamic range
Measurable difference between the brightest highlight (white) and the densest value that any system can create; also, the range of gray values that a system can reproduce Higher values show greater ability of a product to effectively contrast highlights and shadows
The ratio of the maximum output signal to the smallest output signal that can be processed in a system, usually expressed logarithmically in dB Dynamic range can be specified in terms of harmonic distortion, signal to noise ration, or other performance criteria
The difference in signal level between the loudest and quietest parts of a programme, expressed in decibels
The visible and thermal (near infrared) range within which the glass changes As an example, SageGlass® has a visible dynamic range of 4-70% This means that on the low end, it blocks all but 4 percent of incoming visible light, and on the high end, it allows 70% incoming light
Most basically defined as the ratio of the maximum signal strength a circuit can handle to minimum input level at which it can generate an intelligible output
The measurable difference between the brightest highlight and the darkest value
The number of colors or shades of grey that can be represented by a pixel The smallest unit of data stored in a computer is called a bit Dynamic range is a measurement of the number of bits used to represent each pixel in a digital image 1-bit or bitonal means that a pixel can either be black or white Bitonal imaging is good for black and white images, such as line drawings and text However, scanning in grayscale rather than bitonal may produce a better looking image 8-bit color or 8-bit grayscale means that each pixel can be one of 256 shades of color or one of 256 shades of gray 24-bit color means that each pixel can be one of 16 8 million colors
The range between the loudest and the softest sounds that are in a piece of music or that can be reproduced by a piece of audio equipment without distortion This is a ratio expressed in decibels (dB) In speech the range rarely exceeds 40 dB; in music the range can reach over 75 dB In audio, higher numbers are better
An expression of the density difference between highlights and shadows As a measurement of scanner quality, dynamic range is one of the primary differences between low and high quality scanners A desktop scanner with a small dynamic range will yield scanned images that lack detail in shadow areas
The range between the loudest and the softest sounds that are in a piece of music, or that can be reproduced by a piece of audio equipment without distortion (a ratio expressed in decibels) In speech, the range rarely exceeds 40 dB; in music, it is greatest in orchestral works, where the range may be as much as 75 dB
The difference between the loudest and the softest sounds either contained in a piece of musical or other audio material  In reproducing audio material, it means the range that can be reproduced by a piece of audio equipment or audio format without distortion This ratio is expressed in dB
The difference between the loudest point of a sound passage and the softest point Audio systems also have a dynamic range: the difference between the loudest sound the system can record before distortion and the softest signal that can be recorded without introducing noise This range is measured by the signal-to-noise ratio The signal is the actual sound you're after; noise is any hiss or other artifact introduced by the amplifier, microphone, or other electrical components of the audio system
The ratio of a specified maximum level of a parameter, such as power, current, voltage, or frequency, to the minimum detectable value of that parameter
the range of signal levels for which a receiver function properly The lowest signal level is determined by noise level considerations and the upper level is determined by detector or receiver distortion, saturation, or power level limitations
- The difference between the loudest and softest possible sounds a component can produce Rated in decibels, higher numbers are better
The ratio of the maximum (brightest) to minimum (darkest) signal levels present in an image For instance, a true 12-bit digital camera is capable of providing a dynamic range of 4096: 1
The ratio of the saturation to noise, limited by the bit depth of the sensor Dynamic range is expressed numerically (3 0, for example) In the captured image the dynamic range relates to the colour fidelity and contrast range of the picture The greater the dynamic range, the higher the contrast and colour bit depth
A measurement of the accuracy of an image in color or gray level More bits of dynamic range results in finer gradations being preserved
The range in dB between the noise floor of a device and its defined maximum output level The term applies to both audio devices and RF equipment, but the maximum output level is defined differently Back to top Electret Condenser Microphone A type of condenser microphone whose transducer contains an electret material that permanently retains an electrical charge, and does not require the external voltage source required by other types of condenser transducers to polarize the diaphragm
An instruments range, such as a scanner, of measurable values The range is from the lowest value it can detect to the highest value A perfect dynamic range for a scanner is considered to be 4 0 or Dmin=0 and Dmax=4 The dynamic range of a scanner is most indicative of its' overall image quality with 3 0 being a minimum rating for prepress capable scanners
An audio term which refers to the range between the softest and loudest levels a source can produce without distortion
