How loud is 50dbA — Digital Spy
2007年2月20日 · The operating volume at "silent" mode is "<50dba"... I tried running it at "Silent" to test it, and there wasnt much of a noticable difference between full power and silent - both were bloomin loud! So what I'm asking is: how loud is 50dbA?! What is 50dbA comparable to? Its only slightly quieter than the Dyson, is that about right?!
