Patients with sensorineural hearing loss often have a reduced dynamic range, and may experience distortions or discomfort at loud sound levels.
The dynamic range of a system is a meas-ure of its ability to handle a wide range of input amplitude and is defined as the ratio of the largest resolvable signal to the smallest signal that can be handled.
The range of variation between its darkest state and its clearest state that a switchable glazing is capable of. So, for example, one type of SageGlass® IGU has a dynamic range of 4-60%. This means that on the low (dark) end, it blocks all but 4 percent of incoming visible light and almost all the heat, and on the high (clear) end, it blocks only 40 incoming light, allowing in more solar heat. To put that into context, most commercial office buildings today have glass that blocks more than 70% of the incoming light.

Dynamic range describes the ratio of the softest sound to the loudest sound in a musical instrument or piece of electronic equipment. This ratio is measured in decibels (abbreviated as dB) units. Dynamic range measurements are used in audio equipment to indicate a component's maximum output signal and to rate a system's noise floor. As a reference point, the dynamic range of human hearing, the difference between the softest sound we can perceive and the loudest, is about 120 dB. Compressors, expanders, and noise gates are processing devices that are used in audio to alter the dynamic range of a given signal. This is done to achieve a more consistent sound when recording or as a special effect (by radically altering the dynamics of a sound, thereby creating a sound not possible from the original source).
The ratio of the saturation to noise, limited by the bit depth of the sensor. Dynamic range is expressed numerically (3.0, for example).

The dynamic range in a digital system is determined by the data resolution, about 6 dB per digital bit. A 20-bit system has a theoretical dynamic range of 120 dB. The 02R has a specified dynamic range of 105 dB.
The range between the loudest and softest sounds a soundtrack and/or sound system can reproduce properly.
The range between the loudest and quietest parts of an audio signal. TV sound is not very dynamic, with dialogue usually almost at the peak level of the signal. With film sound on DVD there is an large amount of headroom available for sounds louder that dialogue up to 24dB. This is why the output level of a DVD player tends to be set low compared to that of a VCR.
The range between the loudest and softest sounds a sound format or system can reproduce.
In any given device, dynamic range is the range in decibels between the highest level that the device can handle without clipping, and the level at which small signals get absorbed into the noise floor.

For an interferogram, it is the ratio of the large centerburst signal at ZOPD to the smallest recorded signal (which must be greater than the noise for any benefit from signal averaging). The A/D used must have sufficient precision to measure the entire range as any clipping or distortion of the largest signal affects the whole spectrum.
One key feature to look for in a scanner or digital camera is its dynamic range. A scanner's dynamic range depends on the maximum optical density that can be achieved and the number of bits captured. In simple terms, the greater the density range the better the scanner.
Dynamic range describes the range of brightnesses that can be seen by a CCD camera. CCD cameras have a much greater dynamic range than does film. A CCD's ability to capture both faint and bright details in determined by its dynamic range.

The ability of the scanner's CCD to capture the full range of shadows and highlights. A scanner with good dynamic range is able to map input shades correctly to output shades, making images look brighter and giving them more visible detail. Generally, the number of bits determines the maximum dynamic range of a scanner. For example, a 36 bit scanner has a higher dynamic range than a 24-bit scanner.
The difference between the loudest and softest parts of a musical performance, usually measured in decibels.
A term used to define the loudness difference between the softest sound a person can hear, and the loudest sound they can still comfortably tolerate. The dynamic range of hearing is about 120 dB for most people with typical hearing. The dynamic range of the implant user is about 30 dB.

The ratio between the brightest and darkest recordable parts of an image or scene. A scene that ranges from bright sunlight to deep shadows is said to have a high dynamic range, while indoor scenes with less contrast will have a low dynamic range.

The variation in sound levels over time, or the difference between the loudest and quietest sounds measured over a period of time.
has two distinct and different meanings in digital products. Dynamic range is the ratio of the specific maximum signal level capability of a system or component to its noise level. Usually expressed in decibels and used in engineering specifications. Also know as signal to noise ration. Dynamic range is the ratio of contrast, tonal range or density in an image between black and white. The number 0.0 represent white and black is 4.0. A flatbed scanner may have a dynamic range of 2.4-2.7 while a drum scanner may be as high as 3.6-3.8. The numeric ranges stated is the ability of the device to record and reproduce the range of grays between black and white. The higher the number the greater the detail in shadow (black) and highlight (white) reproduced in an image. Film is generally given a dynamic range of 4.0, while digital devices range from 2.4- 3.0 for most digital cameras and scanners. A drum scanner can achieve as high as 3.7 to 3.9. (also see Density Range)

The ratio of the maximum level capability of a system to its least detectable or smallest level (e.g., maximum signal level to system noise level).
The ability of film, sensor or paper to capture smooth gradations of tone across the entire tonal range. All films and sensors can capture black and white, which are the extremes of the tonal range. Dynamic range is an indication of how much between black and white can be recorded. A narrow dynamic range means less of a complete tonal range can be reproduced as compared to a wide or broad dynamic range. Images with a small dynamic range have a tendency to appear contrasty because fewer tones can be captured.
Extent of minimum and maximum operational characteristics. For example, the difference between lowest and highest intensity (for a monitor), or the lowest and highest density (for prints and transparencies).
Dynamic range is the difference between the lowest level of sound that can be heard above the noise of the equipment and the highest level of sound before distortion occurs.
The range of sound intensity a system can reproduce without compressing or distorting the signal.
Typically expressed in dB, dynamic range is defined as the range between the noise floor of a device and its specified maximum output level. An ADC's dynamic range is the range of signal amplitudes which the ADC can resolve; an ADC with a dynamic range of 60dB can resolve signal amplitudes from x to 1000x. Dynamic range is important in communication applications, where signal strengths vary dramatically. If the signal is too large, it over-ranges the ADC input. If the signal is too small, it gets lost in the converter's quantization noise.
1.) The difference between the softest and loudest portions of sound that an amplifier or recorder can reproduce within an acceptable range of distortion. Expressed in decibels (dB), the higher the number the better. 2.) The difference between the maximum signal level and the noise floor of an electronic component.
is the ratio between the brightest and darkest recordable parts of an image or scene. A scene that ranges from bright sunlight to deep shadows is said to have a high dynamic range, while indoor scenes with less contrast will have a low dynamic range. Note that depending on the scene contrast, it may or may not be possible to capture the entire range with a digital camera. In recording scenes with very high dynamic range, digital cameras will make compromises that allow the capture of only the part of the scene that is most important. This compromise is needed because no camera or output device of any kind (including the human eye) can reproduce the nearly infinite dynamic range that exists in real life.
