  2. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    Vinyl microgroove phonograph records typically yield 55-65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB. [25] German magnetic tape in 1941 was reported to have had a dynamic range of 60 dB, [26] though modern-day restoration experts of such tapes note 45-50 dB as the observed dynamic range. [27]

  3. 70 mm film - Wikipedia

    en.wikipedia.org/wiki/70_mm_film

    A 70 mm film strip with a human hand for scale. 70 mm film (or 65 mm film) is a wide high-resolution film gauge for motion picture photography, with a negative area nearly 3.5 times as large as the standard 35 mm motion picture film format. [1] As used in cameras, the film is 65 mm (2.6 in) wide.

    An LP made out of perfect vinyl would have a theoretical dynamic range of 70 dB, [6] though measurements indicate actual performance in the 60 to 70 dB range. [7] [failed verification] Compare this to digital recording. Typically, a 16-bit digital recording has a dynamic range of between 90 and 95 dB. [8]: 132

    Note that each category will include weapons that are in that general size class. Weapons of similar caliber may differ in exact caliber (i.e. 76 mm and 76.2 mm will both be under 76 mm artillery). Non metric calibers are placed within the nearest calculated metric category.

  8. Gauge (firearms) - Wikipedia

    en.wikipedia.org/wiki/Gauge_(firearms)

    A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.

  9. Peak signal-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Peak_signal-to-noise_ratio

    Typical values for the PSNR in lossy image and video compression are between 30 and 50 dB, provided the bit depth is 8 bits, where higher is better. The processing quality of 12-bit images is considered high when the PSNR value is 60 dB or higher. [3] [4] For 16-bit data typical values for the PSNR are between 60 and 80 dB.
