## What is White Noise 3D?

Some people like to work in the cafe, but not in quiet library - some studies show that coffee shop environment will be more conducive to the sound focus, enhance creativity at work, this environment can be considered a kind of sound. " white noise. "

If you like listening to the rain, do not miss this application.

In addition to sound variety, also supports a variety of sound reverberation, and other custom scene.

Writing, running, travel time can be opened to listen!

It contains a variety of natural ambient sound.

Imitate the sounds of nature - this is the white noise (white noise), improve concentration, relaxation, fine.

Refers to white noise in a wide frequency range, the energy of each frequency band included in the noise and other noise equivalent bandwidth. Usually physically translate it into white noise (white noise). White noise or white noise is a constant power spectral density of random signals or random process. In other words, the signal power in each band is the same, since the white light is a mixture of various frequencies (colors) of monochromatic light, so that this signal has the nature of a flat power spectrum is called "white", this signal has therefore been called white noise. Noise signal relative, other do not have this property are called colored noise. Ideal white noise has infinite bandwidth, so its energy is infinite, which is impossible in the real world exists. In fact, we often limited bandwidth of the signal level regarded as white noise, because it makes us more convenient in mathematical analysis. However, the white noise in the mathematical treatment is more convenient, so it is a powerful tool for system analysis. In general, as long as the spectral width of a noise process has the effect that it is much larger than the bandwidth of the system, and its spectral density can basically be considered as a constant in the bandwidth, you can use it as white noise to deal with. For example, thermal noise and shot noise over a wide frequency range with a uniform power spectral density can usually think they are white noise. When you need to concentrate on work, there is always a complex and surrounding sound, you can use these two sounds to be obscured. In general, under normal circumstances you can use the white noise, pink noise is specifically for voice masking material. Pink noise has been known frequency is inversely proportional to (1 / f) noise, because its energy is inversely proportional to the frequency distribution, or every octave (Octave) the energy recession 3dB.

One application is the white noise of architectural acoustics, in order to weaken the internal space distracting and do not want the noise (such as conversation human) appears, use continuous low-intensity noise as background sound. Some sirens of emergency vehicles also use white noise as white noise to pass through cities such as background noise and traffic noise does not cause reflections, it is easier to attract attention. In electronic music also applied white noise, which is directly or as the input signal of the filter to produce other types of noise signals, especially in audio synthesis, often like cymbals for reproducing a high frequency domain so that percussion noise components. White noise is used to generate the impulse response. In order to ensure a balanced effect Venue concerts or other performances, it issued a white noise or pink noise from the PA system instantly, and in a different place to monitor the noise signal, so that engineers can effect a building acoustics can automatically enlarge or cut certain frequencies, which can be adjusted to give effect overall balance a balanced harmony. White noise can be used for frequency response of the filter amplifier or electronic test, sometimes it is used with a flat response microphone or automatic equalizer.

### 5/5 — 免费的

*2026-07-25*

这个是免费的诶，对我这种学生党就很友好，不过广告需要八块钱删掉，但是广告也不多，也有定时关闭，很喜欢

### 5/5 — 簡潔的交互頁面

*2024-08-20*

有自然的白噪音可以選擇、調節音量、對我來說十分好用，提升睡眠質量，看書時聽。感謝開發者

### 5/5 — 让人静心学习的背景音

*2022-10-28*

图书馆或者自习室会有人走动或者翻书的声音，很难静下心学习，带上耳塞也不好使，但是打开这个可以挑选自己喜欢的背景音，和音乐不同，它能让我很快进入学习状态，最喜欢其中的宇宙音效，打开以后甚至能忘记自己身边有人，喜欢喜欢！最棒的一点是，它可以自己混合不同的音效，diy让自己最舒适的声音，这一点好像很多软件都没有，要是能有iPad横屏版就更好了！

### 5/5 — 要求两次评论后可免费消除广告

*2022-01-26*

一开始用的时候是完全没有广告的，自从一次闪退之后，就开始了底下栏出现Google广告，明显地影响使用感。

### 5/5 — 希望大家都来试一试，太好用了

*2021-12-24*

中午午睡的好搭档，看书思考时候也可以打开一起使用，配合降噪耳机用，比起嘈杂的环境音简直是天堂啊！

### 5/5 — 简而惠

*2021-08-15*

虽然不能说这是个小而美的软件，但的确是算得上简而惠。
配合耳机使用，对于需要独立工作环境的人来说，简直太友好了

### 5/5 — 很好

*2021-05-19*

界面简单但这个也不需要太复杂，声音种类要是能再多一些就好了，还有跟随系统的黑暗模式

### 5/5 — 声音种类很多

*2021-04-15*

各种音效搭配起来效果不错，还可以保存自己配的，而且最重要的是可以息屏使用，棒棒哒

### 5/5 — 小小建议

*2021-04-11*

要是音效选择的时候，能点触听到想选的音效就好了，看名字不太能知道是什么声音

### 5/5 — 很不错 推荐使用

*2021-02-25*

里面的白噪音种类很多，而且还都是免费的，还有一个很喜欢的就是它可以定时关闭，这样就可以听着白噪音入眠了
建议：可以增添猫咪打呼噜的声音还有钢琴声音会更好
