A sound wave is the pattern of a disturbance generated by the flow of energy as it propagates away from the source of the sound across a medium (such as air, water, or any other liquid or solid matter). When anything vibrates, it sends waves of energy (vibration) into our ears, whi...
Soundis energy traveling through the air in waves. Sound waves don't look like the waves on the sea—indeed, you can't see them at all. If you could see sound traveling, you'd see it squeezing air molecules together in some places and stretching them out in others. In other words, ...
Making small talk is a way to start a conversation with a stranger when meeting for the first time. It isn't easy to make small talk with people. You don't know. Sitting by yourself and saying nothing at a party is rude. Making small talk is necessary to build business relations. Mak...
Sound may be the last thing you hear at night as well when you listen to your heartbeat and drift gradually into the soundless world of sleep. Sound is fascinating—let's take a closer look at how it works!Photo: Sound is energy we hear made by things that vibrate. Photo by William ...
The choice of lighting in the growth chambers is an important consideration for several reasons. It's important to use energy efficiently in space, because resources are limited. Energy can't be wasted on light bulbs that don't maximize their output. In addition, different types of lighting ...
However, the sound is the same even after exercising. Others say that the whooshing sound inside the shell is generated by air flowing through the shell - air flowing through the shell and out creates a noise. You'll notice that the sound is louder when you lift the shell slightly away ...
“Predictive maintenance is a big thing,” says Schmid. “This lets us limit equipment downtime and improve safety by being proactive about a fix.” The sensors work by analyzing the sound frequencies, vibrations, and temperature of a given machine to tell if it’s working within its normal...
Gordon Raphael, engineer and producer who’s worked with The Strokes and Regina Spektor, told us he’s more interested in music made by humans. “I’m so fascinated by human music,” he said. “…The thing about music that kills me is hearing an experience and a story turned into music...
BMW model names have not always been as clear, simple and structured as they are today. This becomes apparent when we take a look back at the long history of BMW. The first car BMW ever made was christened the BMW 3/15 PS, a licensed model built in 1929. The “PS” in German sto...
For a small sound source radiating energy uniformly in all directions, intensity varies inversely with the square of the distance from the source. That is, at a distance of two feet from the source the intensity is one-fourth as great as it is at a distance of one foot; at three feet ...
