At least seconds we'll be able to hear Google Echo now. Because an echo is a reflection of sound delayed to the listener after a direct sound, the delay will be proportional to the distance of the reflecting surface from the source and listener. An echo is a reflected sound wave. An echo is a reflected sound wave. If this delay is less than a second, the human ear will not be able to distinguish between the cheap sound and the original direct sound. When the temperature is, the speed of sound in dry air is about this site. Therefore, the reflecting object must be farther away from the sound source than the sound source in order to feel the echo. When the sound resonates, it takes about two seconds to stand on it.
The emitter is located meters away. Canyon walls or water-facing cliffs are the most common natural echo-producing barriers in nature. These articles are online complex barriers. We know that when sound encounters an obstacle it Kenya Phone Number List back. So when will we hear the echo from the surface of the sound barrier? Physical experiments show that the smoother the surface of the object, the better the sound reflection effect. For example flat wall vertical cliff mirror site is this marble surface etc. This is also the reason why we often hear echoes when we stand in a newly built house and speak.
Because the sound we emit travels through the air without any resistance, and reach our ears. A finished, furnished home will absorb sound better. Conversely, objects with rough surfaces or uneven surfaces usually reflect less sound. People also call these objects sound-insulating objects or sound-absorbing objects. Normal sound is not reflected when it encounters such surfaces. If the sound encounters a rough surface after being transmitted, the content will not become smaller and will not cause resonance. Sweaters are required at the bubble station.
