Question

The decibel is the unit of Sound Level, which is a convenient way of representing the large range of sound intensities that the ear can detect. From the definition of the decibel we can see that increasing the sound intensity by a factor of ten results in:

Answer 1

Increase of ten yields 10 dB increase

Step-by-step explanation:

The decibel is a logarithmic scale that shortens a large range of numbers into smaller and more manageable numbers. The decibel is found using:

`dB = 10log(r )`

Where r represents a ratio of a measured magnitude (pressure or intensity level in sound) to a reference pressure or intensity value. However, in our problem we only need to represent an increase factor of ten:

`dB = 10log((10)/(1) )\\\\dB = 10*1=10 dB`
