2/19/2023 0 Comments Dark noise vs white noise![]() ![]() The practice of naming kinds of noise after colors started with white noise, a signal whose spectrum has equal power within any equal interval of frequencies. This sense of 'color' for noise signals is similar to the concept of timbre in music (which is also called "tone color" however, the latter is almost always used for sound, and may consider very detailed features of the spectrum. Therefore, each application typically requires noise of a specific color. For example, as audio signals they will sound different to human ears, and as images they will have a visibly different texture. ![]() Different colors of noise have significantly different properties. Thank you.In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Espero que minha máquina dê um pouco de paz e tranquilidade às pessoas que vivem em lugares barulhentos. I hope my machine will give some peace and quiet to people living in noisy places. Em seguida, ele emite um som na frequência oposta que cancela o primeiro som. Then it makes a sound in the opposite frequency that cancels out the first sound. Conforme um som entra no microfone, a máquina determina a frequência do som. As a sound enters the microphone, the machine determines the sound’s frequency. Mas se você pudesse enviar uma onda, ou muitas ondas pequenas, em direção à onda grande, não seria tão poderosa, porque as ondas pequenas iriam atingi-la e reduzir seu tamanho. But if you could send a wave, or many small waves, toward the big wave, it wouldn’t be as powerful, because the small waves would hit it and reduce its size. É como estar no oceano e ver uma grande onda vindo em sua direção. It’s like being in the ocean and seeing a large wave coming toward you. ![]() O ruído branco é formado por ondas invisíveis de som que reduzem os efeitos do ruído escuro, emitindo sons de frequência oposta. ホワイトノイズは正確にはノイズではありません。実際、ホワイトノイズはまったく聞こえません。 White noise is made up of invisible waves of sound that reduce the effects of dark noise by making sounds of the opposite frequency. White noise is not exactly noise in fact, white noise can’t be heard at all. Dark noise is made up of sounds that bother you so much that you can’t concentrate on what you are doing. Have you ever been kept awake at night because of the sound of traffic, or people talking, or loud music? These types of noise are sometimes called dark noise. M: Thank you!įor the science contest this year, I’ve invented a white noise machine. Here’s the winner of this year’s science contest: Charles Moore! Charles, tell everyone about your invention.
