My Lexus LFA sounds really similar to this

Thanks! This let me know that my headphones were messed up. The frequency in my headphones goes up and down, all over the place.
This is the frequency at which alternating current operates on aircraft.
Yup
and a USA phone line
Lloyd Duff No.
excuse me its higher but the same pitch and I know because I have listioned to your phone dial to see if it matches my voice..THANK YOU
Lloyd Duff Okay, I wasn't sure what you were talking about because there's things like 20hz AC on a phone line for ringing current. Standard US dial tone is a mix of 350hz and 440hz. So it is two frequencies that are close to this, but roughly 2 musical semitones in each direction.
400hz... I've always thought that this is the frequency that NEEDS to replace the 1000hz tone that is used to Censor Bleep profanity. 1000hz is better off as the tone for emergency alerts such as severe weather since the intention of the beeps is to get your undivided attention (The EAS already uses something to that effect). 400hz is still loud, but muffled enough so as not to have that 'startling' element that the 1000hz has and therefore, is better suited to censor swearing.

400hz is too laid back to have the alert effect. I think TV stations used the 1000hz tone because it was more defined for Audio adjustment. Also cheaper to use as a tone as 400hz cost more due to adjusting the tone hence costing them more to pay whoever supplied it. Just a thought nothing concreate unless anyone has a better explantion for them
Whenever your television station signs off the air for the night.
I find some of the comments here amusing. The actual tone used by the weather service to alert listeners is 1050Hz, not 1000Hz. That's the single tone you hear at the beginning of a weather alert on NOAA Radio. Weather receivers decode that tone after a certain length of time and trigger the alert warning in the radio (the sound of a wail or siren), or just open the audio so you can hear the NOAA audio.
As for the EBS (now EAS) tones, it's a combination of 853Hz and 960Hz transmitted simultaneously, and at specific lengths of time. One thing you CAN NOT do is to transmit those tones unless there is an actual emergency. The FCC gets very upset and very involved when people think it's cute to use those tones on the air when no emergency exists and will fine your a$$ off for doing so! Having worked in radio for 40 years, I became very familiar with the EBS (EAS) tones, how they were used, and when we could use them.
Personally, I think the 1000Hz tone for beeping out profanity isn't used properly. It's often way too loud for the general program content it's used in. You can beep out words with a lower level tone and still have the same effect, while not blowing listeners out of their chairs!
This is the sound my great Gramp's pulse monitor makes.
Wow your gramp's heartbeat is hella fast. Respect
Why is my speaker spitting on me
Lol that means you got water in the speakers. 400 hertz pushes the water out. I use this audio to clean out the water every time I get my phone wet.
This tone was used in USA and Japan for TV test tone.
400 hz is the most common ac frequency for planes, qnd this sounds like a hum over a plane radio
I had headache from this xD
It can damage your hearing
@@flatcapman Awesome! I want to hear this with my headset! :D
I have a better idea. Come To Australia. Our accents sound like this tone
Szrenka Adam same bro
If you work on airplanes you know this one.
The 1986-1989 Black Screen of death tone heard at the end of certain Warner Bros Cheesy Shield tapes, Disney buena vista tapes, and a few others.
That was nice. It sounded very nice.
with the right volume and setting it's a chill out tone
nice 400hz
Yup. The note here is Ab 4 tuned -027. If you can play G 4(middle G) on a 448.98 hertz instrument, you should get 4 hectohertz.
i got g4
This tone has a strange effect on me. It sends me into a trance. Always has. I feel deeply its a part of me and 1000hz makes me alert 400hz puts me to sleep with my eyes open. I call it "the Family tone" and I see it the same as my finger prints. If you think hearing this is intense wait till you hear a person talk in it with a SMPTE ripple
In fact if you turn this tone all the way up and put your speaker close to your ear you can feel air moving through it
I used this to calibrate a cassette player and when it played fast I checked the frequency with an analyzer app and it said that it was 368hz when I calibrated the cassette player to 368hz it played perfect
Did you know 80-400 Hz sounds can make a spider freeze???
The end of tapes does have the low pitched black screen of death by 1984-1989.
Everybody is gangsta until the sound is still on and it came from someone near you in a hospital

Using this to fault diagnose rfi on an aircraft
This is beautiful 😍
my brain started tweaking what
I have been doing research on mosquitoes and apparently this is the perfect sound to attract them because it is similar to the beat of a females wings
It's really weird cause if you just hum it does the thing where two frequencies contrast.
Good evening sir Sonic Electronix, thank you so much sir.
I love you
LFA gang
Apparently spiders don’t like 80hz to 400hz so I’m playing this to get rid of spiders found 8 in my home within 2days
Why does it sound lower in my right ear but higher in my left
I'm sencing this sound from a vast place with great purpose. I can't put my finger on why the voices in my head are telling me of grand significance. That probably sounds crazy.😂
I don't think your crazy. I have Autism and Im sensing something from this tone. And even an evolution where the tone can evolve to a Human voice using upper and lower tones to denote words in pitch. This sound is Australian and the 1000hz one is clearly "English" 2 different men=one streamline
Ancient forgotten civilisation have build several perfect geometrical rooms directly in a massiv stone in India wich resonate very well with this frequency, but we don't know why... (400hz 800hz 1000hz 1200hz)
if you like 400 that much, you should try 432. and learn about solfeggio frequencies. sounds are powerful. the nervous system uses frequencies to communicate to the body. In the same way we are subtly influenced by plant hormones when we eat them, sounds can subtly influence our bodies as well. I have holes in my skull that make my brain perceive sounds as my body moving, and I am extremely sensitive to different frequencies, as you appear to be.
@@chironOwlglass that doesnt explain how 400hz can hynotise me
400hz is the natural frequency of the earth and it has a great significance to the pyramids.
me tring to scare a spider:
this tone gives me serious headache, its the same call tone on whatsapp
Brancher a bourd? Ne penser pas de brancher au prises murales dans l'environs de la galere. Les systems d'alimentations electriques sure Des avions commerciaux marchent normalement a 115 volts C.A. a 400HZ. C'est sufficient pour abimer gravement votre laptop. Les prises dans les salles de bains marchent a voltage regulier (110v60Hz). Mais plusiers sont deconnectees.
Sound like korean kbs and sbs sign off
Snow In tha phone foh today
a 300 cent sharp G
This sound causes spiders to stop in their tracks. They freeze up. Anything between 80 to 400 hz will work fine
I’ve heard people use this in songs to make the melody sound better. Idk
God singing
I felt a pressure drop in my blood vessels after listening to this. What if sound waves could ultrasonically clean corroded blood vessels?
This frequency is used for Neck issues
i closed my eye and it feels me different sound
my skull is vibrating
If you listened very closely to my former girlfriend's head you would hear this exact sound.
Or the way I snore
Mmm 200 hz

Can this kill mosquitos ??
Had the volume up too loud and it hertz!

Im too busy toneing to take that
Lo tuve al maximo
Вау, ни одного комментария на русском!

Is it really 400 Hz? I thought youtube compresses audios the time you upload it
its 400hz I remember the exact sound from our CRT TV back in the day
Lloyd Duff nope. A CRT would make 15,000 Hz. Sky: compression would not change a file’s frequency. A sine wave is the simplest sound, so it is the easiest thing for digital compressors to describe. It would therefore not change at all.
@@allanreilly5827 mate I seen enough tv sign offs to know the difference and i know my own tone thank you. I even dreamed I toned it out of my mouth and coming from a person? YES ITS NOT ROMANTIC IT WAS CREEPY. BTW you are wrong because a Sine wave can be not only amped but can be used as a weapon as well because if you jack it to jet HZ you can not only blow a person's head apart but the vibration from the backfeed would dissolve human bones as well. think Im kidding? OK put 1000hz in G Major on You Tube and NEVER listion to it with headphones unless you desire to be deaf for life..HE WILL MAKE YOUR EARS BLEED. Static is just boring No ghosts but a test pattern can be dangerious
Lloyd Duff Well you specified CRT, so it sounded like you were talking about the flyback transformer. That is 15,000 hz. The TV sign-off would come out of your speaker and so the display type would be irrelevant. I think they used that tone because it is good for finding problems in an audio circuit. You can look at the tone on a waveform monitor and different kinds of problems will change the shape you see in predictable ways. As for using sound as a weapon, that was always too impractical for real world use. Bombs are far cheaper and more predictable. :0
@@Alllgr Also a signal can be hidden under a test pattern signal with a scrambler. If it matches the broadcast it's masked under the bars. In the x-files wetwired it caused people to kill showing halluctnations and Mulder nearly got shot by an infected Scully who thought he betrayed her to the cancer man. In Videodrome they bragged their service could be hidden under a test pattern. This isnt like a bomb because everyone had a TV then and its a mass infection on anyone who sees the bars. My point is it CAN be used as a weapon like anything else and Tom Foolery is a test patterns weakest flaw. A ghost can use static but the living can alter a test pattern and in the wrong hands it can kill a LOT of people so it is HARDLY impractical esp. since some nutjob wont give a flying rats ass how many he kills
It wasn't that loud. Wasn't bad at all.
Loud
Only the one who likes this?
not only the one I love this tone and even use it as self ID. This tone can hypnotise me so I can sleep with my eyes open. I go into a trance
telephone sound
My voice tone is over 400 hz.. 😇😂 and lowest note is almost 60 hz
A human voice never goes over 40hz sorry to say. Unless your not human
@@flatcapman your not human
Yeah no my headphones are broken
It’s Japanese dial tone.
Sailor Moon
METAL GEAR SOLID
I find this annoying. Other hertz frequencies are ok. This gave me a headache.
@Mrs Mimi H My 2 older brothers found me watching an Australian Test Pattern with this tone going and I was in a trance like state like I was asleep with my eyes open. They switched it and that snapped me out of it but with a shocked and loud UGHHHHHHHH. I got told off "that's not a sci fi show THATS A TEST PATTERN MAN" They explained what that was
This sound scares me-
You sound better then ladies saying it turns them on THAT scares me
@@flatcapman im- LMFAO- yeah this definitely does NOT turn me on- it turns me o f f
@@_paisleymchugh_2346 I think it wasn't meant to be aimed at a person. More like a 1000hz tone
Qui enlève l’eau de son tel
Wtf
its a test tone for TV back in the day to test Audio
Did you know Travis scott played 400Hz at his concerts?!
he played the Sine wave tone?
You fell for the 4chan trolls 😭😂
