Bubble gum Bubble gum Bubble gum is a type of chewing gum, designed to be inflated out of the mouth as a bubble. In 1928, Walter Diemer, an accountant for the Fleer Chewing Gum Company in Philadelphia, was experimenting with new gum recipes. One recipe was found to be less sticky than regular chewing gum, and stretched more easily. This gum became highly successful and was eventually named by the president of Fleer as Dubble Bubble because of its stretchy texture. The original bubble gum was pink in color because that was the dye that Diemer had most on hand at the
Pink noise interest. Systems that do not have a flat response can be equalized by creating an inverse filter using a graphic equalizer. Because pink noise has a tendency to occur in natural physical systems, it is often useful in audio production. Pink noise can be processed, filtered, and/or effects can be added to produce desired sounds. Pink-noise generators are commercially available. One parameter of noise, the peak versus average energy contents, or crest factor, is important for testing purposes, such as for audio power amplifier and loudspeaker capabilities because the signal power is a direct function of the crest factor.
