Q: What happens to the sound level when the intensity of sound is increased by a factor of 10?

Solution: An increase in intensity by a factor of 10 results in an increase of 10 dB, but the sound level increases by 20 dB.

Steps: 6

Step 1: Understand that sound intensity is a measure of how much sound energy is passing through a certain area.
Step 2: Know that sound level is measured in decibels (dB), which is a logarithmic scale.
Step 3: Realize that an increase in intensity by a factor of 10 means the sound is 10 times more powerful.
Step 4: Remember that for every 10 times increase in intensity, the sound level increases by 10 dB.
Step 5: However, the sound level is actually calculated using a formula that results in a 20 dB increase when intensity increases by a factor of 10.
Step 6: Conclude that when the intensity of sound is increased by a factor of 10, the sound level increases by 20 dB.
