Discussion in 'Vehicles' started by DJ-916, Jun 3, 2016. DJ-916 Member Location: Sacramento. I'm thinking about getting an older beater for driving and I don't see any limitations for mileage in either lyft or uber's requirements but I've ran across a couple random posts about a 100,000 mile limit. Does anyone know if there is such a limit for either company? Thanks!
Audible sound is the sound which is between 20 Hertz to 20000 Hertz and can be heard by human beings, whereas Inaudible sound may be below 20 Hertz or above 20000 Hertz and thâ¦is can't be heard by human beings.
Now the ATI Silencer 1 (Rev. 2) gives the definition of sone here in somewhat subjective terms. For example: nearly inaudible in a computer case is highly relative to many factors and not nearly as definitive as it should be. What would help, would be if I could find some relation between sone and dB (or dBa). For Example if I knew that 1 sone = 25dB (or dBa) I would have a better feeling for how comparatively noisy each VGA coolers fan was.
