Big Ben Sound is the name of the sound made by the clock tower at the Palace of Westminster in London, England. The sound is composed of a dong, PEAL, CHIME, BONG, and hur. The dong is a deep sound that is heard four times an hour, the PEAL is a series of eight bells that are rung every 15 minutes, the CHIME is a single bell that is rung every quarter hour, the BONG is a single bell that is rung every half hour, and the hur is a single bell that is rung every three hours. All together, these sounds create the iconic Big Ben Sound.
