question 23

Multiple Choice

Use the formula $\mathrm { D } = 10.0 \log \left( \mathrm { S } _ { \mathrm { S } } \mathrm { S } \right)$ , where the loudness of a sound in decibels is determined by $\mathrm { S }$ , the number of watt/ $/ \mathrm { m } ^ { 2 }$ produced by the soundwave, and $\mathrm { S } _ { 0 } = 1.00 \times 10 ^ { - 12 } \mathrm { watt } / \mathrm { m } ^ { 2 }$ . A certain noise produces $8.54 \times 10 ^ { - 5 }$ watt $/ \mathrm { m } ^ { 2 }$ of power. What is the decibel level of this noise? (Round to the nearest unit.)

• A) 8 decibels
• B) 69 decibels
• C) 183 decibels
• D) 79 decibels
