How many times more intense is a 60 dB sound than a 30 dB sound?

Options

  1. A2
  2. B4
  3. C1000
  4. D10000

Correct answer

C. 1000

Step-by-step solution

Loudness of two sounds are given as L ₂=60 ~dB and L ₁=30 ~dB Loudness of sound L=10 ₁₀ I I ₀ array ll & L₂-L₁=10 ₁₀ I₂ I₁ & 60-30=10 ₁₀ I₂ I₁ & ₁₀ I₂ I₁ =3 & I₂ I₁ =10^3 I₂=1000 I₁ array
