Axiom Home Page Forums General Discussion Technical Questions blind testing of speakers

1 db represents the difference in loudness that an average human can detect as being different. However, does perception of sound quality (verses loudness) dip into a fractional level? This I do not know, thus I ask.

Also, it will require more than your average radio shack db meter to accurately measure into small fractions of a db and there is also the variations of the frequencies to consider as noted above.

Therefore, for me, I think that for home listening tests, getting within a db is a reasonable goal but I guess it depends on the answer to the above question.

EDIT: My post was being written as Alan posted his ahead of me. I'll let it stand as I'm too lazy to rethink my questions.
