Hello and welcome to JustAnswer!
IF the a/c compressor is excessively noisy it's either because of an internal failure, lack of lubrication, or a restriction in the system.
Oil is carried to the compressor along with the refrigerant and circulates around the system. If for some reason there is little oil in the system, such as if the system was flushed and not enough oil was reintroduced afterward, then it can cause compressor noise. The compressor won't last long in that state.
A restriction could cause noise. If the condensor was restricted for instance and high side pressure was climbing too high then it can cause excessive compressor noise.
If pressures are good and oil doesn't appear to be an issue then the compressor itself would be the cause of the noise. They do get noisier with age and if it's loud enough to be offensive then it will need to be replaced.
