The noise levels during space rocket launch is in the range of

A: 100-120 dB
B: 120-140 dB
C: 140-160 dB
D: 160-190 dB

The answer is: D

Explanation

The noise levels during a space rocket launch typically fall within the range of:

(D) 160-190 dB.

During a rocket launch, the noise generated is extremely intense and can reach levels as high as 160 to 190 decibels (dB) or even higher. These noise levels are extremely loud and far above the threshold of pain for human hearing.

Rocket launches produce intense noise due to the powerful rocket engines and the rapid release of energy during liftoff. The noise is created by the combustion of propellant and the expulsion of gases at high velocities. The sound waves generated by the rocket engines propagate through the air and can cause significant vibrations and pressure changes in the surrounding environment.

Due to the high noise levels, strict safety protocols are in place to protect personnel, equipment, and the surrounding area during rocket launches. Launch facilities often have safety zones and distance restrictions for spectators and personnel. Additionally, measures such as sound barriers, acoustic shielding, and structural designs are implemented to mitigate the effects of the intense noise.

It is worth noting that the specific noise levels during a rocket launch can vary depending on factors such as the size and type of rocket, launch site conditions, and the distance from the launch pad. However, noise levels in the range of 160-190 dB are commonly observed during space rocket launches.
