## What is NoiseWall?

Noisy neighbours can make many people’s homes feel uninhabitable.
This app can help you to cover this noises and keep your focus in your studies, work or sleep better.

Important
Use headphones or external speakers to produce low noise frequencies. 


With this app you can easily generate four types of noises:

White Noise - 20Hz to 20.000Hz - All the frequencies in same level;

Pink Noise - 20Hz to 20.000 (More bass sound than white noise, because is formed by a algorithm with decrease in volume level when increasing frequency);

Brown Noise - Lower frequencies mix -  Sounds like thunder, distant plane or rocket; 

Custom Noise - You can apply a low cut frequency filter to get your own noise!

The sounds are produced in real time, they are not pre-recorded sounds.
This enables to play them without interruption, without loops.

The goal is to create a wall of sound that cover other noises that may be bothering you, allowing study, sleep or simply relax without being disturbed by external noises.
These continuous sounds also help to calm fussy babies.

### 5/5 — Best noise cancelling app

*2025-02-23, version 1.2.1*

Purpose: Cancels noise by creating a “wall” of white noise.

Pros: 
-Free
-cheap ad removal (although the ads are no trouble) 
-highly customizable
-good noise cancelling

Cons: 
-hard to use if you don’t understand how the noise cancelling works
-Controls are mostly intuitive but can be a struggle for some

### 5/5 — Works perfectly

*2023-09-18, version 1.2.1*

Perfect for me worked great. Went travelling and it helped with all the loud hostels i stayed in

### 1/5 — Why?

*2023-08-29*

It is just loud whooshing white noise. Like a thousand nails being driven into my eyes and teeth

**Developer response:** Please read the app description.

### 1/5 — Rubbish

*2023-06-25, version 1.2.1*

It doesn't block any noise when you say oh it blocked noise it just makes more

### 1/5 — Just another white noise app.

*2022-06-12, version 1.2.1*

Useless that I’ll be deleting in 5 mins. The user has to set white noise frequencies, but you can tinker that for hours. The least the dev. could’ve done was offer to record ambient noise, isolate different frequencies and the auto cancel specific noises. Even if not that, then at least label different sliders with the sort of noise they intend to cancel

### 5/5 — Great white noise app

*2022-05-26*

The best white noise generator app, it has 4 very good white noise sounds which you could mix all 4 together if you want and it can mix with other apps and play in the background. You could also adjust the volume for each noise but I wished there was a volume reset button so that it could all reset back to normal volume.

### 5/5 — Love the frequency cut-off feature!

*2020-03-05*

Chop the frequency and make some“black noise.” I love this App. Up to 4 different noise tracks at once.

### 1/5 — Rubbish

*2020-01-15, version 1.2.1*

Rubbish, does not block noise, just makes more noise.
