Question

a) 93.0 dB
b) 96.0 dB
c) 93.0 dB
d) 96.0 dB

Answer 1

The decibel level of a sound that is twice as intense as a 90.0 dB sound is 93.0 dB.

Step-by-step explanation:

According to the information provided, when one sound is twice as intense as another, it has a sound level about 3 dB higher.

Therefore, if we have a sound that is twice as intense as a 90.0 dB sound, its decibel level would be approximately 90.0 dB + 3 dB = 93.0 dB.

So, the correct answer is option (a) 93.0 dB.
