How much stronger is a sound of 90 decibels compared to a sound of 80 decibels?

The concept of sound intensity measured in decibels (dB) is based on a logarithmic scale. Each increase of 10 decibels represents a tenfold increase in intensity. Therefore, when comparing a sound of 90 decibels to one of 80 decibels, the difference is 10 decibels.

This 10-decibel increase corresponds to a sound that is 10 times more intense or "stronger" than the lower sound level. Consequently, the sound measuring 90 decibels is indeed 10 times stronger than the sound measuring 80 decibels. This logarithmic nature of the decibel scale is fundamental to understanding how sound levels compare in terms of intensity.
