Understanding Decibels

What makes the decibel scale different from other measurement scales?

• It is a linear scale.

• It is based on powers of 10.

• It measures length.

• It is used for temperature.

How many Bells is an 80 decibel sound equivalent to?

• 8 Bells

• 6 Bells

• 10 Bells

• 4 Bells

What is the intensity difference between an 80 decibel sound and a 40 decibel sound?

• 100,000 times more intense

• 1,000 times more intense

• 10,000 times more intense

• 100 times more intense

If a sound is 110 decibels, how many times more intense is it than a 50 decibel sound?

• 10,000,000 times

• 10,000 times

• 100,000 times

• 1,000,000 times

What is the first step in comparing the intensity of two sounds using decibels?

• Add the decibels.

• Find the difference in decibels.

• Convert decibels to Bells.

• Multiply the decibels.
