Questions & Step-by-Step Solutions

What is the decibel level of a sound that is 10 times more intense than a reference sound at 0 dB?
  • Step 1: Understand that the decibel (dB) scale measures sound intensity logarithmically.
  • Step 2: Know that a sound that is 10 times more intense than a reference sound increases the decibel level by 10 dB.
  • Step 3: Since the reference sound is at 0 dB, add 10 dB to it.
  • Step 4: Calculate 0 dB + 10 dB = 10 dB.
  • Step 5: Conclude that the decibel level of the sound that is 10 times more intense than the reference sound is 10 dB.
