Final answer:
For every 10-decibel increase in sound intensity, the loudness is 10 times greater.
Step-by-step explanation:
For every 10-decibel increase in the intensity of sound, the loudness is 10 times greater.
For example, if one sound has an intensity of 60 dB and another sound has an intensity of 70 dB, the second sound is 10 times louder than the first sound.
Similarly, if one sound has an intensity of 80 dB and another sound has an intensity of 90 dB, the second sound is also 10 times louder than the first sound.
The decibel (dB) scale is logarithmic, specifically based on a logarithm to the base 10. The relationship between the intensity of sound and the perceived loudness is not linear; rather, it's logarithmic. The key insight is that for every 10-decibel increase in intensity, the sound is perceived as being 10 times louder.
