The Metrodome was recognized as one of the loudest venues in which to view a game, due in part to the fact that sound was recycled throughout the stadium because of the fabric domed roof. Stadium loudness is a sports marketing issue, as the noise lends the home team a home advantage against the visiting team. Until its demolition, the Metrodome was the loudest domed NFL stadium. During the 1987 World Series and 1991 World Series, peak decibel levels were measured at 125 and 118 respectively compared to a jet airliner—both close to the threshold of pain.
