Questions & Step-by-Step Solutions
What is the decibel level of a sound that is 10 times more intense than the reference level?
Step 1: Understand that decibels (dB) measure sound intensity on a logarithmic scale.
Step 2: Know that the reference level for sound intensity is 0 dB.
Step 3: Recognize that an increase of 10 dB means the sound intensity is 10 times greater.
Step 4: Since we want to find the decibel level for a sound that is 10 times more intense than the reference level, we need to increase the dB level by 10 dB.
Step 5: Increase the reference level (0 dB) by 10 dB to get 10 dB.
Step 6: To find the decibel level for a sound that is 10 times more intense than 10 dB, increase it by another 10 dB.
