Decibel level

Not sure if the correct forum.

To the common ear — is there much difference between 90db and 97db

Looking at buying a pressure washer and these are the decibel ratings. Or another way, would a neighbour even notice the difference between these 2 levels?

I've no idea, but if you Google how loud 90db is you get all sorts of results:
Lawnmowers
Power tools
Blenders
Hair dryers

Thanks. How does the scale go up from 90 to 97, just a linear fashion is it?

No, it's logarithmic

98 is a hand drill on that page.

Of course, that raises the question of distance.

Ah right, so the difference between 90 and 97db is relatively substantial
