Adaptive Sound Technologies LectroFan High Fidelity White Noise Sound Machine with 20 Unique Non-Looping Fan and White Noise Sounds and Sleep Timer

数年前から謎の低周波音が聞こえるようになり、特に睡眠時には気になり睡眠障害でした。 こちらのブラウンノイズで耳障りな低周波音がかき消され悩みが解消されました！ 寝室の睡眠用とリビングの休憩時のために2台購入しました。

多少効果はあります。家が高速道路の近くにあるため少し騒がしいのですが、これを使うとある程度効果があります。

真下の住人のTVやラジオの騒音対策として最初にスリープミー、その後こちらを購入しました。 ○： デジタルなのでUSB接続と細かい音量・音源セッティングができる。 スリープミーより軽量でコンパクト。 ✖️： 素材がプラでチャチ。ボタンもチャチでペコペコな感触。 USBアダプタ経由の場合、他機器の接続を受けて音が途切れたり勝手に電源OFFになることがある。 （スリープミーともに）筐体がプラなので騒音を拾い反響し、かえって耳障りな時が多々ある。 共振は消せない。 前からスマホアプリ＋音楽用のBluetoothスピーカーで対策していて休ませたくて購入したけれど、総じてスマホ＋スピーカーの方が効果的で休ませられていません。スピーカーが上向きなので上階の騒音対策には良さそうです。 なおco.jpで買うなら、この円安のご時世でも.comで買った方が送料込でも安いです。

I looked all over the Internet for a sound machine. I do not enjoy animal, rain or outdoor noises, I LOVE the sound of a fan or window air conditioner unit. If you do, buy this one! I was super impressed with the fan sound options, Sounds identical to my summer air conditioner. I actually bought this because there was a comment from someone else saying it sounds like their fan. That's exactly what I wanted, and why I've left a review to help others. I'm Canadian and my skin cannot afford to have a fan on it with our harsh winter temperatures. It blocks out the noise from traffic and other humans in my house. The machine has no lights emitting from it, it's a nice size, and I personally enjoy the 24 hour feature. (These were all things I was very specific in finding) This product is a 10/10 for me. UPDATE: 5 months later and this machine is still the best purchase I've ever made. I absolutely love this sound machine. I used to fall asleep with my tv on for the noise, but after buying a health tracker band that tracks my sleep quality, the tv was no longer an option. I bought this and within a few days I felt much more rested and my tracker showed the difference in sleep. I turn it on when I'm getting ready to go to bed, select the one sound I always use, and leave it on until I wake up and switch it off. (One time I left it on, you couldn't hear it from the hallway but it was still a loud setting in my room. But the surprise was, the machine wasn't hot and I was gone for 12 hours!) I will be bringing this with me on my upcoming road trip for hotel sleep. It truely has improved my sleep and energy levels.

This item works for me even on low volume. Plenty of white noise and fan modes (10 of each) to find one that suits you. If you have a problem sleeping due to external noises, neighbours, traffic, wind, etc. and can't take to ear plugs it is worth a try. Note the unit comes with the USA connector on the charging lead, it has to be removed by simply untwisting it before you can fit the UK adaptor, this isn't explained with the instructions.

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.

I am using this device for the past 3 Years and it has been a great purchase.

Nice compact unit. Works well, as designed..!!
