Question
What is the decibel level of a sound that is twice as intense as a 90.0 -dB sound? (b) What is the decibel level of a sound that is one-fifth as intense as a 90.0-dB sound?
Step 1
Step 1: The decibel level of a sound is given by the formula: \[ \beta = 10 \log \left( \frac{I}{I_0} \right) \] where \( \beta \) is the decibel level, \( I \) is the intensity of the sound, and \( I_0 \) is the reference intensity. Show more…
