### 5 Multiple Choice Questions

1. each 10 decibel jump is ten times higher than the previous number

-difference of 10 decibels means the sound is twice as loud

-if the intensity of sound is increased by a factor of 100, the new sound level will be 20 units greater
2. watt per square meter
3. you can use the equation (dB=10xlog (IO/IR) to find the number of decibels of the output either above or below the reference
4. the ratio increases, raising the power of the log and increasing the number of decibels
5. amount of energy transmitted per second over an area of one square meter

### 5 True/False Questions

1. What other terms can be sued to describe the strength of sound (other than strict intensity)?you can use the equation (dB=10xlog (IO/IR) to find the number of decibels of the output either above or below the reference

2. WHen does intensity level exist?amount of energy transmitted per second over an area of one square meter

3. What is the absolute measure of intensity?watt per square meter

4. How do you solve for the number of decibels using an intensity reference?watt per square meter

5. Is sound intensity the same physical quantity as sound pressure?the ratio increases, raising the power of the log and increasing the number of decibels
