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.
â¢ Extra: If you yourself were able to hear the Mosquito sound, you can test your absolute limit for hearing high-frequency sounds by progressively listening to sounds with even higher frequencies. If you couldnât hear the Mosquito sound, you can still test your limits by starting with a lower frequency and working your way up. YouTube's frequency of 12 kHz might be a good sound to start with.
