Pretty self explainable.
Why do they not create a sonic boom when they enter Earths atmosphere

How do you know that they do?
Not saying i don't believe you, just curious.
Wikipedia said:Any sound generated by a meteor in the upper atmosphere, such as a sonic boom, should not be heard until many seconds after the meteor disappeared. However, in certain instances, for example during the Leonid meteor shower of 2001, several people reported sounds described as "crackling", "swishing", or "hissing"[18] occurring at the same instant as a meteor flare. Similar sounds have also been reported during intense displays of Earth's auroras.[19][20][21][22]
Sound recordings made under controlled conditions in Mongolia in 1998 by a team led by Slaven Garaj, a physicist at the Swiss Federal Institute of Technology at Lausanne, support the contention that the sounds are real.[23]
How these sounds could be generated, assuming they are in fact real, remains something of a mystery. It has been hypothesized by some scientists at NASA as that the turbulent ionized wake of a meteor interacts with the magnetic field of the Earth, generating pulses of radio waves. As the trail dissipates, megawatts of electromagnetic energy could be released, with a peak in the power spectrum at audio frequencies. Physical vibrations induced by the electromagnetic impulses would then be heard if they are powerful enough to make grasses, plants, eyeglass frames, and other conductive materials vibrate.[24][25][26][27] This proposed mechanism, although proven to be plausible by laboratory work, remains unsupported by corresponding measurements in the field.

Shooting stars, also known as meteors, do not make a noise because they are traveling through the vacuum of space where there is no air for sound waves to travel through. Sound waves need a medium, such as air, to travel and be heard by our ears. Since space is mostly empty and devoid of air, there is no medium for the sound of a shooting star to travel through.
No, even if a shooting star were to enter the Earth's atmosphere and get close to the surface, it still would not make a noise. The sound would only be heard if the meteor were large enough to create a sonic boom, which is rare. Most meteors burn up in the atmosphere and do not have enough mass to create a sonic boom.
Some people may think they have heard a noise when they saw a shooting star, but this is most likely due to a phenomenon called the "exploding head syndrome." This is a type of auditory hallucination where people hear loud noises, such as a bang or a roar, when falling asleep or waking up. The visual stimulation of seeing a shooting star may trigger this auditory hallucination in some people.
No, other objects in space, such as planets, asteroids, and comets, do not make a noise when they move. This is because they are moving through the same vacuum of space where there is no medium for sound waves to travel through. However, some objects, like planets, may have magnetic fields that can produce radio waves that can be detected by instruments on Earth.
Yes, there are some rare cases where a shooting star may make a noise. This is usually when a meteor is large enough to create a sonic boom as it enters the atmosphere. However, this is very rare and most shooting stars do not make a noise. Additionally, some meteors may make a hissing or crackling noise as they burn up in the atmosphere, but this is not a sound that can be heard by the human ear.
