I do not have any tools to measure the sound level and I have been running studded winter tires for the last 10 years (Subaru WRX-Mistu Outlander-CX5 2013 and now a CX5-2016) so for me the sound is normal (on dry asphalt people hear me come, not a bad thing). It is very difficult to judge from my point of view, I know they are louder than non studded tires, but at the same time, technology has improved quite a bit, the Hakka 7 are more quiet than the Hakka 5 I had, and I think the Hakka 8 are even better (my next set probably, unless the 9 are out). They are louder than the summer Toyo A23, the only thing I can say which will probably turn you off from studded tires, is that when I put them on in the fall, I find them loud for a day or two, after that it doesn't bother me. At the end of winter I can appreciate the decrease in sound when I put my summer wheels, I am not denying that. For me it is all a question of do you really want studded or not, if yes you are ready to live with the noise, if noise turn you off, there are enough good studless tires on the market to satisfy your need, but for me nothing beats a studded tire on ice (that is why i live with the noise). One big + of the studded Hakka, they do not wear fast, i am on my 4th winter with them and i am still at 8/32. I think i could do another winter and maybe 2.
