science and exciting world of research imagination and the willingness to join us on a strange Journey as by unlikely experiments together into one astounding Discovery changing our lives forever open a door in your mind and step through into the realm of weird Connection in this episode how the world's most revolting irritating and annoying noises could become an instrument to help control a turbulent world all in just five weird connect this journey begins with this man recording the sound of someone losing their lunch sound of his own nose sniffing and the munching of an apple that's for being sick to his stomach he didn't do that himself he hired an actor to do it somebody could recording who did all the right things into a bucket Trevor Cox is not a Hollywood sound effects wizard he is a professor of Acoustics at the University of Salford in England although it may sound a little offbeat he still being a serious subject what was signed in the world was very much but leave the room is not really very nice we don't know why do you respond so strongly to the Suns just wanted to know why some noises Sparks such a negative reaction dim into three categories disgusting the most grading and the most infuriating sound known to humankind on a scale of truly bad and just Apple the worst thing you've ever heard 5 1/2 head first physics went to the University campus the cacophony of nasty computer cases of the worst 22 alarm clock at number 16 stop barking dog at number 14a ringing cell phone at number six a badly played violin and in second place microphone feedback identify is the world's worst sound number one we have the sound of someone throwing up we find vomiting nausea because of something cold of disgust reaction because he's in the Philippines but what about the other some sounds are unpleasant because they reminded . just hearing the swirling of a drill is like when I head home I feel the dentist going in for the kill increasing pain painful associations and discussed explain the most of the sounds on the countdown some sounds didn't fit into either revulsion Association categories for instance why would something like Styrofoam rate so high on the list I mean it's something that cause you to ask me something nasty so it kind of seems to me much lot unit intrinsic actual sound itself other squeaky sounds like microphone feedback and badly played violins couldn't explain by disgust or Association sounds that was disturbing it was their pitch Sound Vibrations tickle the hairs that line the basilar membrane in our cochlea sending signals to our brain process this sounds brain sometimes find high pitch sound confusing if we take a nice Selfie song note lots of different parts of a cell membrane which move in different ways at the same time the high rate of vibration is simply too fast for the interviewer to cope with voices are there still no Spanish for let's just say baked beans in a bucket but how would Professor cost is 7 Discovery Health you may not the search for the worst sound in the world could have a calming effect on an unruly mob but in just five weird connections were going to find out how would lead to the Sound of Silence we began our Strange Journey with a repulsive noise now we had two whales and an even more challenging problem repulsive Behavior security expert Howard Stapleton lives in South Wales professional skills when his eldest daughter was harassed at a local grocery store teenagers wanting can I send my Vincent Ultra spell to go and get some milk she came back into the site with no milk. What happened in there being about the group of tents without the Moon 12 to 15 year old boys hang around outside restaurants in shabam the following died I went and spoke to them. And he knew I was in spirit Industries sells brass instrument an iPhone than the public cameras is now it is only with those end up with nice to teach your kids behaving badly and I'm functioning as you get very precise position is very little theater which is converter necessity is the mother of a tension and Stapleton remembered an unpleasant experience from his own childhood that might solve the problem I then remembered back to when I was about to live in 12 years old and I actually thought my father was the bustle I used to take with absolute welding and put one on top of my head so if it sounds the sound of the ultrasonic welding had been unbearable young Howard so why wasn't anyone else in the real reacting I know I'm a Potato. looks around the rest of the group and everyone just put that check in the head stay woke up thinking I was joking about the sound they were experiencing a known as presbycusis literally how you relate to care anymore on the first phone for the hearing took I would die into the ability to hear the high frequency the tiny hairs that line frequency receptors are the first to go so the older you get the less you can hear high pitched sounds Stapleton determined that if he could come up with a device by the store fronts any lawn mowers it is kitchen table design in the machine I would tell me how annoying the noise was sent out to a meal I could hear it using a test subject what would be the sound that drove them distraction finally he founded that no teenager would be able to. now all that was left was to see if his mosquito would bite he got the opportunity after receiving a call from the owner of the store where his daughter had been harassed on that one I'm down there and they going for market open on Sunday in Islam horrible noises coming through me On Demand have an awesome wonder why this sounds like a perfect solution to many of the teenagers still the principles behind device will set the tone for some sound new site but what's all that got to do with this man in weird connection number one noises in the world's worst connection number to the frequency that turn off public tennis and now connection number three we put the spotlight on Channel high frequency sound waves is an unassuming tigrat with the powers of a superhero he can whisper directly in the ears of patrons at the local library from way up in the balcony pompeya cheese this seemingly superhuman feet with a gizmo he invented called the audio spot it's a speaker that focuses sound at a specific Target Pompeii was your average teenager always stereo equipment he had a gift for engineering and design he made an incredible scientific breakthrough that really what the shortcomings of traditional loudspeakers were he realizes that regular loudspeakers directional sound a loudspeaker is like the light bulb the sound is created really cuz everywhere the young engineer wanted to direct sound just like a laser pointer that you can fuse cats with not that mathematically there are only two options to make speakers act like lasers used or only broadcast the same frequencies Howard Stapleton use to deter teens in into the reason lies in the way audio waves travel through the air low frequency Audio Waves like bass sounds have more time to spread out over a larger area as they travel short frequency waves reach their targets faster so to get high frequency sounds frightened people away and that wasn't what Pompeii was trying to do so he needed another option in order to create a Sound Source that's directional either you need to limit only to extremely high frequencies for you need to have a loudspeaker that's tens of meters across when create a speaker that big certainly the beam is that big so it doesn't do very well when you want to Target one person or one small area it seemed that pompey's project was doomed very rare and science to get to a stopping point where you real flies that corn in the math and according to all known Theory something's just not possible their doctoral program and direct them toward the next new possibility using ultrasound waves to create his audio beam ultrasound waves are even shorter than Howard Stapleton not even a teenager and also makes them highly directional if Pompey ultrasound lazarbeam several sleepless nights later Define we made the math work this Theory there is always moving even and it's still rude how these are currents would strike the ultrasound waves and convert them into frequencies we can actually here since the ultrasound waves are highly directional the resulting the audible sound was perfect abilities of this device work and list one of the fun things we used to do is get up on the balcony five stories up in our laboratory building and in the sound down at people walking below sometimes we beam Fashion Glass sounds of the Caterers walking by with dishes I would whisper in people's ears and it was all great fun has Grown Ups cast of the time what you did yesterday directional sound during Pompeii award and the year of mini but can it help restore calm when the pizzas. and what is the audio Spotlight have to do with what this man is doing in his car as we ride the audio way too weird connection number for in our first three weird connections the revolting to the irritating Swiffer sites channel of disturbance now we're just two steps of a control this is the median on a mission in the world the knowing is Neighbors he's test on a deserted Airfield clear laser like directional sound has an Aficionado of classical music to Midian was intrigued by a new kind of audio amplifier the soap planar magnetic speakers speakers the planar magnetic speaker that I got to hear cost $6 it was a very very small very very low power but it has unbelievable intelligibility turn it up very loud that's when I began to see if we could make this thing like on steroids and have this thing powerful we could take over the music unfortunately the big the worst they sounded in for this complex problem all speakers one of the very interesting characteristics of our technology is that is pulled dipole that means that the speaker sends out as much energy in this direction as it sends out mattress in someone's like two speakers the resulting creation was also more directional individual small speaker transmits wave as it spreads out and the results sounds louder and more directional Force Base in Southern California for the ultimate if it was light enough Fairfield enough for the Moment of Truth has arrived from more than half covid-19 human pain speaker system one of the loudest and most Direction devices ever built the largest speaker that we've ever created with is what we call 96 is capable of sending sound 56000 ft for 10 Mi perfectly intelligible comedians Innovation for outdoor concert goers bring just to the final Connection in this music lovers are not the only fans of some idioms new technology the United States military is training soldiers this situational training exercise brings together all 4 weird connections the high pitch sounds that Professor Cox determined are inherently of Aura to humans in connection won the ear splitting tones perceptible only to the young and section 2 and the audio that can be being too specific listeners and for a non-lethal powerful sound deterrent large walls speakers can raise the ears putting tone to a painful decibel level some of them will just cover their ears the majority of them will leave the area they just don't want to deal with that type of military experts estimate lethal weapons can potentially save hundreds if not thousands of it is to pull over and get that crowd to disperse anything that would keep us from having to raise our level of force people on both sides the piercing high-pitched Cry of non-lethal audio Weaponry may help while violets and disperse angry Mobs with a single shot having to be fired in five weird connection we have found the very best use for the very worst cities in the world if all this comes from the sound of throwing up imagine what else is possible
