Noise level in dB = 10Log10 (Noise in watts)
10 dB = 10Log10 (Noise in watts)
Noise in watts for 10 dB = 101 = 10 Watts …(1)
1dB = 10 Log10 (Noise in watts)
Noise in watts for 1 dB = 100.1 = 1.26….(2)
P1/P2 = 10/1.26 = 7.94 W

Explanation:
Comparing Noise Levels:
- The decibel (dB) scale is logarithmic, meaning that each increase of 10 dB represents a noise level that is 10 times more powerful.
Calculating the Difference:
- The noise level of 10 dB is 10 times more powerful than the noise level of 1 dB. This is because 10 dB is one increment higher on the logarithmic scale than 1 dB.
Therefore, the noise level of 10 dB is 10 times more powerful than the noise level of 1 dB.
