DB (until 1947 known as Deutsch-Bonnet) was a French automobile maker between 1938 and 1961, based in Champigny-sur-Marne near Paris. The firm was founded by Charles Deutsch and René Bonnet. Immediately before the war the partners concentrated on making light-weight racing cars, but a few years after the war, starting with the presentation of a Panhard based cabriolet at the 1950 Paris Motor Show, the company began to produce small road-going sports cars. By 1952 the company no longer had its own stand at the Paris motorshow, but one of their cars appeared as a star attraction on the large Panhard stand, reflecting the level of cooperation between the two businesses.

A weighting filter is used to emphasize or suppress some aspects of a phenomenon compared to others, for measurement or other purposes.
A-weighting is the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. A-weighting is applied to instrument-measured sound levels in effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies. It is employed by arithmetically adding a table of values, listed by octave or third-octave bands, to the measured sound pressure levels in dB. The resulting octave band measurements are usually added (logarithmic method) to provide a single A-weighted value describing the sound; the units are written as dB(A). Other weighting sets of values - B, C, D and now Z - are discussed below.
Sound is a vibration that propagates as a mechanical wave of pressure and displacement, through some medium (such as air or water). Sometimes ''sound'' refers to only those vibrations with frequencies that are within the range of hearing for humans or for a particular animal.
''Dragon Ball '', ドラゴンボール, Doragon Bōru is a Japanese manga series written and illustrated by Akira Toriyama.

The series follows the adventures of the protagonist, Goku, from his childhood through adulthood as he trains in martial arts and explores the world in search of the seven orbs known as the Dragon Balls, which summon a wish-granting dragon when gathered. Along his journey, Goku makes several friends and battles a wide variety of villains, many of whom also seek the Dragon Balls.

The ''Daily Bugle'' (at one time ''The DB'') is a fictional New York City tabloid newspaper that is a regular fixture in the Marvel Universe, most prominently in Spider-Man comic titles and their derivative media. The newspaper first appeared in '' Fantastic Four'' #2 (January 1962), and its offices in '' The Amazing Spider-Man'' #1 (March 1963). The ''Daily Bugle'' was first featured on film in the 2002 film '' Spider-Man''. The fictional newspaper is meant to be a pastiche of both the New York '' Daily News'' and the '' New York Post'', two popular real-life New York City tabloids.
