Download version 2.1.0 released on 02.07.2016. This requires at least Windows 7 SP1. For an operating system before Windows 8, if you aren't current with all the updates, you might have to first install Microsoft's .Net 4.5 from here.

To run the program, unzip the downloaded file where you want, and run the executable file.

There are two programs included in the archive: Noisette is geared toward generating sounds and can play a single sound at a time, NoisetteX allows you to play simultaneously several sound files or playlists. You should use lengthy sound files or else you will hear interruptions when the playing starts again.

Noisette is a program which continuously plays white noise. It's useful for people who live or work in a noisy place, people who want to cover the stressful background noise.

"White noise" refers to a specific type of sound, but is also used as a generic term for noises which sound like static / hissing, huge waterfalls or heavy rain.

White noise is very effective in providing a wall of sound against environmental noise, but can't cover screams or the beats of a subwoofer. Theoretically, it might cover them, but it would have to be so loud that it would itself become the problem. Grueling sounds, like the "Hard sledge hammer" sound generated by Noisette, can cover a neighbor's subwoofer, but they create their own (severe) problems.

You can also use a white noise machine or a fan (or air conditioner), but they are not as practical and generate drafts. Audio files and computer software are far more flexible, especially regarding the volume control and the diversity of sounds.

When listening to white noise, you should use two standalone, high quality speakers; a 2.0 speaker system is a good choice. Notebook, tablet or phone speakers are no good. High quality speakers can give a lot of power to the low frequencies, which makes the noises sound "deeper"; however, a subwoofer would create annoyingly powerful low frequencies.

It may surprise you to hear that grueling sounds, like "Hard sledge hammer", can calm a hyperactive brain. This happens because such sounds disrupts the brain's activity, including hyperactivity. But since the cause of the hyperactivity doesn't disappear, the calm is temporary. Be aware that the side effects are quite strong on both brain activity and ear, so limit the use of such sounds.

Standalone noises

Here are some white noise sound files, each with a 5'000 seconds duration: Air - Smooth (Air: hp 100hz-48db, lp 15'000hz-48db), Medium air - Smooth (Medium air: hp 100hz-48db, lp 15'000hz-48db), High air - Smooth (High air: hp 100hz-48db, lp 15'000hz-48db), Air - Deep (Air: hp 100hz-48db lp 2000hz-48db), Air - Stratospheric (Air: hp 100hz-48db lp 400hz-48db), Rain - Smooth (Rain: hp 100hz-48db, lp 15'000hz-48db), Static; right-click a link and choose "Save target / link as" in order to save each file on your computer. When you click on a link, modern browsers start streaming the noise, so that you can see which ones you like. You can play them with NoisetteX or any sound player.

"Air" is, technically, a type of brown noise, but unlike brown noise, it doesn't exhibit high frequency fluttering, that is, it's a much smoother noise, especially at high volumes.

Some noises are derived from the original, by applying effects (indicated in parenthesis) in Audacity, as follows: "hp" - high pass filter, "lp" - low pass filter, "hz" – frequency (= threshold above / below which to preserve frequencies), "db" – rolloff (= volume reduction of low / high frequencies), "g" – gain (= volume increase of remaining frequencies). A high pass filter removes subtle patterns with low frequencies. A low pass filter can create sounds with low frequencies which sound like a deep rumble, even if the original sound is just static.

Here you can see a number of sound files and videoclips with various relaxation sounds. If you want relaxation, also look there for ASMR.

Remote control

Noisette and NoisetteX can be controlled with a Windows Media Center remote control.

The "Play", "Pause / Resume", "Stop", "OK", "Enter", "Space" keys stop or toggle playing.

The "0"..."9" keys play the sound with the specified index ("0" is for 10).

Reactive noise

Reactive noise allows the program to play a sound only when there is noise in the environment.

If there is noise in the environment, the program plays the currently selected sound. If the noise in the environment stops, the program stops playing the currently selected sound.

In the main window of the program, when the "Threshold" check-box is active, the currently selected sound is played only if for the last 10 seconds the default microphone connected to the computer records environmental noise whose discreet volume samples exceed the specified threshold in more than 50% of cases.

This 10-50 rule ensures that the program will start playing a sound only when there is a sustained noise in the environment, not when there is a sudden, short noise.

When the "Play what microphone records" check-box is active, the program will also play what it records through the computer's microphone.

The microphone integrated in a notebook or tablet is perfectly usable for this feature.

Editing sound

You can use Audacity to edit sound files, and save them as MP3s (that you can play on an external player).

When you want to repeat a sound file by appending it to itself, after you copy and paste the file to itself use the "Effect \ Repair" menu function (on the join area) to remove any click noises which may have occurred (at the join).

If you want to make a noise sound less stereo and more mono (that is, sound less in-your-ears), use the "Stereo butterfly" Nyquist filter (you first have to import it from the website).


SPL is the local pressure deviation from the atmospheric pressure, caused by a sound wave.

SPL represents an important factor in comparing the "power" of speakers, especially of subwoofers. The higher the SPL is, the more powerful a speaker sounds. The SPL written in the specifications of speakers is normally measured at 1 m away.

An SPL of about 130 creates a sound shock wave powerful enough to be felt as a hit in the chest, but there have to be about 140 to feel the chest pounding. A jet engine has an SPL of 150 dB, a vuvuzele horn has 120 dB, jack hammer 100 dB, refrigerator 40 dB.

The dB scale is logarithmic, so 10 dB represents a doubling of the perceived sound volume / loudness. A 10 dB increase of the SPL means that the sound amplifier needs 10 times more power (electrical, not RMS). Doubling the distance decreases the SPL (and the perceived sound volume / loudness) with 6 dB.

In order to get low frequency sounds to sound as intense as high frequency sounds, dedicated speakers (like subwoofers) must be used because normal speakers can't produce low frequency sounds with a high intensity.

To decide whether to get a ported or sealed subwoofer, see this.

Stressful music

Why is the music from a neighbor so stressful?

The problem isn't the music's high volume, but the use of a subwoofer, the high volume of the bass (= the low frequencies), and the fact that the walls filter out the high frequencies, reduce the medium ones, and let pass the very low ones with virtually no influence.

Why is bass felt whereas "normal" sound heard? Because:

  • The bass contains beats (= sound separated by short pauses), of about 1 second, which pass through the walls, forming wall-sized shock waves that envelope the people on the other side, and are felt (not just heard) as percussions / impacts, just like cannon shots are felt. Beats literally feel like someone is hitting you every second or so, for hours on end; it's torture. If a low frequency sound isn't interrupted, it's perceived as a pressure wave (= hum) instead of a shock wave.

  • The air pressure created by a subwoofer (which generates the audible low frequencies of bass) is much higher than that created by the satellite speakers (which generate the audible high frequencies).

  • The human ear is much less sensitive to low frequencies than to high frequencies, so a subwoofer's volume (= output energy) has to be increased much more than the volume of the satellite speakers.

  • High frequencies are absorbed by walls much easier, so they are absorbed before they reach the other side. For example, for each doubling of the frequency, a brick wall provides more sound insulation with about 5 dB.

The long-term physiological effects of bass include high blood pressure, heart fluttering (which feels like a butterfly's touch), stomach and esophagus burning sensations. Silence actually promotes brain development.

If you ever feel the need to ask a neighbor to turn the music down, instead, ask them to not use the subwoofer, at least when they listen to music for a long time. The problem is that most subwoofers which come with satellite speakers can't be turned off independently from the satellites, so they should turn the subwoofer's volume to the minimum, but this might not be effective because subwoofers have a quite significant minimum volume.

You can try telling the neighbor something like "You have a subwoofer that can be heard for hours, and it's very stressing. Please don't use the subwoofer when you listen to music for hours. (At least turn the subwoofer's volume at minimum.)"

When trying to find out from where sound is coming, be aware that simply listening from inside of your home is pointless. Sound, especially bass, can appear to come from one place but actually comes from the opposite direction. To find out the source, you have to listen to doors because they have the lowest sound insulation.

Running on tablets

It's possible to run the program on tablets which have full Windows.

However, by default, Windows on tablets uses a sleep mode called "connected standby", mode which once active stops all desktop applications (but not the ModernUI ones).

Because of this, network downloads stop, instant messengers don't receive messages, email clients don't check for new mail, sound stops, and so on.

In this mode, if the tablet's display is turned off, the connected standby mode is activated, that is, there is no separation between the display and the sleep mode.

In order to deactivate the connected standby and keep the desktop applications running when the display turns off, you have change something in the tablet's registry.

Go to the "HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ Power \ CSEnabled" key and set its value to 0 (from its default value of 1). Then restart the computer. Then, in the current power plan set the time after which the display is turned off.

Note that once the connected standby mode is deactivated, the tablet can no longer sleep, though it can hibernate, so even if the display is turned off, the tablet will consume a lot more energy than with the connected standby mode active.

Known issues

Sometimes you may hear a faint pattern in the noise. Some patterns may be present in noise itself, but some appear only from time to time. If this happens, it's most likely that you have to reboot your computer. Phones are the worst in this regard. If rebooting doesn't fix this issue, try to restart your speakers as well (the amplifier integrated in your speakers might introduce patterns); also try to shutdown and then start your computer and speakers. Also check the sockets and transformers because some may be whistling, and unplug anything from the sockets, and unplug the transformers from the sockets.
