Mission SM3 Sound Intensity and DeciBel Levels

Mission SM3 focuses on the meaning of sound intensity and the use of the deciBel scale to compare the intensity of sounds. The mission consists of 36 questions organized into 9 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

• The student should be able to recognize the role of the deciBel system and understand its logarithmic nature.
• The student should be able to compare sounds in terms of their intensity and deciBel level.

If you are not familiar with this topic, then you should first learn about the topic using our written Tutorial or our Video Tutorial:
 

• What property of a sound wave is described by its deciBel rating?
• How is sound intensity mathematically related to the deciBel level of a sound?
• If the ratio of the intensities of two sounds is known, what can be known about their deciBel levels?
• If the deciBel levels of two sounds are known, what can be said about their intensity levels?
