Adaptive Sound Technologies LectroFan Classic White Noise Machine – Compact Sleep Sound Machine for Bedroom, Travel, Study and More – 20 Non-Looping Fan & White Noise Variations – Black

HELPFUL TIPS… for the best sound machine.
UPDATE 2014-FEB-14– After owning the device a couple weeks, I had some realizations about why the Lectrofan is the best product. Other white noise machines often do not allow a very full range of pitch from high to low. The Dohm, for instance, does have a pleasing sound, but it is not capable of changing pitch too much, just muffling it really, changing the tone some too. Changing the pitch is the SMART way to block out particular sounds. If my roomie downstairs is listening to music from his cell phone or a higher pitched video game, turning the lectrofan on higher pitch blocks it out without having to blast the volume. If is he is blasting bass from his stereo, the lower pitches work better.The low rumbling of White Noise 1 (lowest Pitch) may have a pleasing sound (very much like “Brown Noise,” a wonderful sound that many of you researching this topic have probably heard), but it will actually fail to mask many sounds that are higher pitch. Do not make the mistake of leaving it on the lowest pitch and just blasting the volume every time you need to block out louder noise. I suppose that white noise 4-6 would be the best general sound-blocking pitches for when you have a variety of noise in the environment. This kind of use is impossible with something like the Dohm, which I used for a long time before this. There are many sounds which the Dohm will never block without trying to use brute force with the volume (and it doesn’t get anywhere near as loud as the lectrofan.) And the Lectrofan can be turned so loud that your room can sound like you are living under a waterfall or something– so it can basically block out almost any environmental sound (though of course the reality will always be that you have to have it louder than the sound you are trying to block, which is the principle of all the sound conditioners. The point is that the sound is constant and you are not distracted by all the changes in noise.)– I didn’t think I would use the fan sounds too much- I just figured I wanted the white noise. The fan sounds are actually pretty nice. They are soothing and with no perceptible loop (lectrofan told me they were actually algorithms making the noise and not any recording of a fan.) The fans do have one issue that some people will enjoy and others will not, and most people may not even notice. They do have a repeating change in bass, which I notice more than others because I am neurotic about sounds. This change in bass will be more apparent if you have headphones on or earplugs in, but you might like it as a nice constancy. I doubled up on the lectrofans so I could get a richer sound in my room (which is very cool for white noise), but unfortunately the wobbly bass sound of the fans becomes even more distracting then. Others may enjoy this. The major downside of the fans is that they do not have the same range in pitch as the white noise, so they can not do the targeted kind of sound-masking I described above. I suspect people who are not very sensitive or neurotic (i.e., anal) about these kinds of issues will really enjoy the fans, though. I guess they are probably more realistic for having this trait.– The white noise is pleasant. Higher pitches sound unpleasant at first, but give them a chance, maybe lower the volume. They end up sounding like fans, or rain, or a distant waterfall over time. I have the lectrofans in my room on white noise, but it still kind of sounds like the rushing of air or some other sound in nature with a similar pitch; the brain kind of fills in the gaps or hears what it wants from so general a sound. The sounds grow on you. Sometimes I will be sitting here hearing it as a waterfall, other times I will hear the same sound as air from an airconditioner or a huge downpour of rain. It is a really interesting phenomenon. Or maybe I am just crazy.– The customer service was great. My first purchase would rattle when I turned the volume up to the highest levels. They sent me a replacement with two day shipping promptly with no questions asked. The new device gets VERY loud (way louder than the Marpac Dohm, it’s main competitor) without losing quality.– I owned a Dohm, but do not use it anymore. This device is more efficient, smaller, louder, and produces a better quality of sound and a wider range of sound. My Dohm started rattling after a few months and so I looked for a better product. Thank God this had been released recently.

The Best Noise Machine Out There
I keep one in my suitcase. I have one that I use every night at home in our bedroom. I keep one in the spare room and I have one near the couch if that becomes my sleeping spot. This unit’s noises don’t skip, click, start over, or make a repetative sound. I am a ridiculously light sleeper. Works great. A variety of sounds to choose from. There is a volume control. I’ve had a couple for a few years already. You can plug into the wall or use a USB that is included.

Excellent at blocking extraneous noise!!! The machine comes w/ European/UK/USA plugs. Shall travel with it. Haven’t slept w/ earlplugs since receiving it. Wish I had bought this years ago!

Es un aparato pequeño, que cabe sin estorbar en el escritorio o mesa de noche, pero su bocina es potente.Se puede conectar con un cable USB a la computadora o a un cargador de celular.Genera varias frecuencias de ruido blanco y simula sonidos de ventiladores, que ayudan a dormir o a concentrarse en un ambiente ruidoso, debido a que están tapando lo que suena alrededor.El sonido que produce no es música relajante ni nada es eso, es algo como un motor de avión, monótono y denso. Se puede decir que es algo como un desodorizante que se usa en el baño, que probablemente no es un perfume bonito, pero es fuerte, no es desagradable y su función es ocultar olores más feos.Obviamente si hay una apisonadora trabajando al lado o un escándalo muy fuerte, el dispositivo no va a poder tapar el ruido de este tipo, pero es muy recomendable para personas que quieren eliminar ruidos más tenues, sin embargo molestos, como televisión, voces, vecinos, perros etc.
