I am curious as to why 45 rpm reissue is dead quiet. Is it because it is a reissue and/or because of the 45 rpm speed. If it is related to the speed, how is this so??
Steve,
honestly i don't know for sure why they are quiet, but i have a few ideas about it. the speed relates to more information being given for a specific time of the music. so it's not so much a 'lower noise' as a 'more musical information' deal.
--they are sold at a premium and so are always mastered and pressed to the highest standards.
--they are cut without concern for space so the gooves can be wider and so the signal to noise ratio is better.
--my older 45 rpm pressings from the 70's and 80's are not as quiet as the re-issues from the last 10-15 years. i'm guessing that they've made advances in lower noise processes.
--jackets and liners are better and these are clean pressings.
--these pressing are handled with care by their owners and so live a sheltered life.
i have over 1000 of these and i can pull any of them out and expect to not hear even one pop or crackle. not that you don't occasionally hear one, but when you do it's a surprise.
to your original question; it very well could be that the higher speed does result in less noise, but i don't really know about how that might work.
