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.
Generally speaking, the flatter a line is, the better the speaker will sound. The Echo has much stronger response between 300 and 1400 Hz, which is where most of the sounds of human voices reside. A few other performance characteristics are worth noting. For starters, in our tests the Echo played +4.5 dB louder than the Home. In a bedroom or kitchen, such a difference probably doesnât matter, but in a very large living room the Home might not sound loud enough. The Echo is a true omnidirectional speaker, too, so it will more easily fill a large space with sound.
