• The British sometimes call Sonar, ASDICS, it stands for Anti-Submarine Detection Investigation Committee.
• Long-distance Sonar “pings” have lower frequencies. The lowest have a very low "BAH-WONG" noise.
• Sonar can be used in the air for robotic navigation.
• In the 19th century people used underwater bells in lighthouses to give warning of hazards.
• During World War I people needed to detect submarines so much that more research of sound was done.
• A bat's sonar is so sensitive that they can detect a fishing line.
• Bats use sonar to detect their children in a crowded cave.
• A dolphin's sonar is so sensitive that they can detect a shark a half mile away.
