Why would it be possible to determine the multiplication factor for the sound intensity that increases the sound intensity level by 22.0 dB without knowing the initial sound intensity? What is the numerical value of the factor?

• A. i) The ratio (I₂/I₁) doe not require the value of I₁ ii) 158
• B. i) The ratio (I₂/I₁) doe not require the value of I₁ ii) 0.00631
• C. i) The difference (I₂ - I₁) doe not require the value of I₁ ii) 158
• D. i) The difference (I₂ - I₁) doe not require the value of I₁ ii) 0.00631
• E. i) The ratio (I₂/I₁) doe not require the value of I₁ ii) 2.92
• F. i) The ratio (I₂/I₁) doe not require the value of I₁ ii) 0.342
• G. i) The difference (I₂ - I₁) doe not require the value of I₁ ii) 0.342
• H. i) The difference (I₂ - I₁) doe not require the value of I₁ ii) 2.92
