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, when I had the test done in a sound booth by an audiologist, I only had minor ultra high frequency hearing loss and according to them could hear up to 18k. What I heard was not a tone, but this weird humming sound and I explained that to the audiologist that it did not sound like a tone at all to me, but they just brushed it off.
