The equation relates the sound level, , in decibels (dB), of a noise with an intensity of I to the smallest sound intensity that can be heard by the human ear, (approximately watts/meter2). The maximum intensity of a car horn is approximately 0.01 watts/meter2. Based on this information, which value is closest to the maximum sound level, in decibels, of a car horn?
