Take a look at the attached paper for further info.

Also, while noise itself is not necessarily a problem, high noise levels indicate large pressure drops which can cause a lot of wear and tear on valve trim. If you have not already, you might want to talk to the valve supplier about this.

However, as you can imagine, in a non-industrial setting, it gets LOUD. Normally the specification is for less than 80 dBa.
So, we use noise reduction techniques. There are valve trim options to mitigate the noise at the valve source, or orifice plates after the valve to break up the pressure drop to reduce the noise and also muffler devices after the valve that absorb the noise.
