In geography a sound is a large sea or ocean inlet larger than a bay, deeper than a bight, wider than a fjord, or it may identify a narrow sea or ocean channel between two bodies of land (see also strait).There is little consistency in the use of 'sound' in English-language cartography.Traditionally in northern European usage, the Sound is the Øresund, the strait that separates Denmark (the outermost Danish island being Sjælland) and Sweden, the narrow channel (2.5 miles or 4 kilometers wide) that connects the Kattegat with the Baltic Sea.
