One type of ear plugs can block sounds as loud as 28 dB. A second type can block sounds nine times as intense. For how many more decibels is the second type of ear plugs effective?

The second type of earplugs can block sounds as loud as 28 * log(9) = 25.2 dB.

The difference in decibels between the two types of earplugs is 25.2 - 28 = 23.4 dB.

So the answer is 23.4

This answer is pure absurd BullShit! 

A typical intentionally WRONG answer presented by the forum’s Wrong Answer Troll (WAT).
