Questions & Step-by-Step Solutions

What is the decibel level of a sound that is 10 times more intense than the reference level of 0 dB?
  • Step 1: Understand that the decibel (dB) scale is logarithmic, meaning each increase of 10 dB represents a tenfold increase in intensity.
  • Step 2: The reference level is defined as 0 dB.
  • Step 3: If a sound is 10 times more intense than the reference level (0 dB), it corresponds to an increase of 10 dB.
  • Step 4: Therefore, the decibel level of the sound is 0 dB + 10 dB = 10 dB.
