The loudest animal on Earth is the blue whale. Blue whales can emit sound with an intensity of 106.8 watts/meter. The equation B = 10 log() relates the sound level, B, in decibels (dB), of a nolse with an intensity of I to the smallest sound intensity that can be heard

by the human ear, 10 (approximately 1 x 10–12 watts/meter?).

Based on this information, which value is closest to the sound level, in decibels, of the vocalizations of a blue whale?

OA.

240 dB

OB.

1,000 dB

Ос.

140 dB

OD
