Answer 1

`\mathbf{\beta=140\ dB}`

Explanation:

The Logarithm Function

The sound level is usually calculated as a logarithm by the formula:

`\displaystyle \beta=10\log(I)/(I_o)`

Where

I = Sound intensity in W/square meter

Io = Smallest sound intensity that can be heard.

`I_o=1\cdot 10^(-12)\ W/m^2`

The blue whale can emit a sound of I=106.8 W/square meter, thus the sound level is:

`\displaystyle \beta=10\log(106.8)/(1\cdot 10^(-12))`

`\displaystyle \beta=10*14`

`\mathbf{\beta=140\ dB}`
