Question:
The range of sound level of a jet aircraft at take-off stage is around
The range of sound level of a jet aircraft at take-off stage is around
Show Hint
Typical sound levels:
\[
\boxed{
\begin{aligned}
\text{Normal conversation} &\approx 60\ \text{dB}\\
\text{Busy traffic} &\approx 80\text{--}90\ \text{dB}\\
\text{Jet aircraft (take-off)} &\approx 100\text{--}110\ \text{dB}
\end{aligned}
}
\]

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recall typical environmental noise levels.
A jet aircraft during take-off generates extremely high sound levels.
Step 2: Identify the closest range. The typical sound level is approximately \[ \boxed{100\text{--}110\ \text{dB}} \] Hence, \[ \boxed{(C)} \] is the correct answer.
Step 2: Identify the closest range. The typical sound level is approximately \[ \boxed{100\text{--}110\ \text{dB}} \] Hence, \[ \boxed{(C)} \] is the correct answer.
