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.
phyregod !!YTINASNI. Nope, a real resonator is a glass pack or small muffler looking thing, designed to mellow out the tone of your exhaust. Used in conjunction with your catalytic converter (emissions) and your muffler (self explainatory), the resonator attempts to break up the sound of each combustion into more of a hum. If you put your lips together and blow, out comes THBBBBBBT!.. Do the same thing to a horn, and you get a pleasant, solid tone instead.
