from quality to flash from causing people to top this is where it is they are. welcome to the 77 percent. this week and the w. v. listen what do you hear music kids playing a neighbor drilling raindrops hammering against the window your own heart to beat the world we live in is noisy sound is everywhere even in business in fact sound is business and that's our topic today on made but to have you with us if you live

like mean next to a busy road you'll know the frustration of having to cope with noisy costs passing by night and day but maybe just maybe they'll be a time when all those noisy engines will be replaced by electric vehicles but what sounds like a blessing could actually be a curse because electric vehicles off so quiet but and cyclists can't hear them coming and that's dangerous and that is why the e.u. is requiring an acoustic warning device leaving it to design us to come up with a fake yet authentic sound. for sound designers combustion engine noises are as complex as symphonies. and they provide the basis for developing artificial motor sounds for electric cars at present they sound like this. when did you know we're going to consider the

mating call of a stag. was this country or a tiger or whatever is not the chirping of a sparrow. office mature sound like that does something to a driver menace said to meet at your bellowing noise that signifies the. time of greatest. does this buzzing sound zain india doesn't have such an immediate and powerful impact but it could come to signify another kind of power that's expressive in its own right and of power. the challenge is to develop that power for electric cars. that disempower. car dealer benyamin davidge says a timid buzz just doesn't do it for him he loves the full throated growl and roar of 500 horsepower. figure does it not matter too that's just part of it

for many people with. big engine big sound great sound lights soft that means performance passion fun behind the wheel when everything good and exciting about driving as you head into the sunset in your sports car to move on and going for it. but how can a letter vehicles be fitted with a truly authentic sounding fake sound. in this we're going 151617 kilometers an hour the noise is minimal i'm going to tweak the sound quality. i've just boosted the higher frequencies. the new e.u. regulations says new electric cars will have to be equipped with an acoustic vehicle alerting system which makes a sound at low speed entering reversing. the. it's not that the e.u.

wants to make the world sound better and cooler for us all it's about safety you have to be able to hear if an electric car is just 10 meters away heading at you or 20 kilometers an hour. and the sound has to be distinctive and easy to hear fish cut out for. sound design or just want to shape the experience of those inside the car as well as outside it's also about branding. despommier by my 50 years ago most eighty's had a special distinctive sound and it had to do with the substance of the cars the sound was authentic just like it also came to stand for stability and safety those times are over now you can fake everything so you keep wondering does anything actually sound like what it really is is. driving pleasure reliability safety all that has to be suggested by the sound of a car mom. but i

feel there's a lot of research being done in this area and what they always find is that people customers car buyers what a car does sound like a car that's part of the culture that's what they've learned. so when an electric car set soften the future it might sound something like this. but sound designer think that won't be the last word in the matter they 1st see further developments. going to the next generation won't care about cars making sounds like combustion engines once there are only electric cars on the streets they want to expect any extra added sounds that just won't matter. so we can start over with fresh ideas.

why shouldn't a chorus sound like a flying saucer for example or anything else one might care to dream up. we could all get rather interesting. i still consider the sound. sound is everywhere and affects us whether we realize it or not i mean it sounds pleasant and soothing like birds singing. laughter. and of course iraq sling wind. now all of us off far far less appealing sounds like silverware scratching across a tall slim plate screeching child across a block of thought or the relentless noise of traffic. well for better or worse was rounded by sound so let's find out more about how it affects us.

setting the tone how sounds affect us. what's that noise it's a faulty washing machine our ears never switch off they can perceive frequencies between 20 and 20000 hertz even when we're sleeping that can alert us to potential dangers. high pitched sounds like chalk squeaking on a blackboard put our teeth on edge where the lapping of waves is coming. business also seeks to exploit the powers of sound music influences are subconsciously triggering emotions but it is good music also good business. we tend to linger longer in department stores and are likely to buy more if we hear slow peaceful sounds but not every type of music has that effect the music has to appeal to us personally or sukey ambience apparently we're more likely to buy french wine if we

hear french music playing. according to another study we spend an average of 6 euros $75.00 on wine when we had classical music while will only pay an average of $1.00 euro $95.00 if pop music is playing but we don't buy more bottles. from playing sounds people rubbing their hands together drumming on tin cans accompanied by whispering voices. some people say videos on you tube calm them down make their scalps feel all tingly. some fast food outlets or do it yourself stores have already used these kinds of videos in advertising campaigns. by the way researchers say dairy cows produce 7.5 percent more milk when beethoven is played to them. has played. whereas popular music for example seems to cut more

by some 2.5 percent. another study indicated that sounds can even change the way swiss and ages to use exposed to hip hop was judged to be the funkiest. funky cheese thanks to hip hop music who would have thought so sound can be used to guide our behavior manipulate our consumption and maybe even make us more productive and sound can wholesome be used for pure sensation a case in point is the brain tangle known as a s m are all autonomous sensory rhydian response that is apparently triggered by certain audio visual content as m.r. videos are huge on the internet and it's a trend that shows no sign of slowing down. more than 13000000 videos that revolve around one thing.

a.s.m. are stands for autonomous sensory meridian response it's that pleasant scalp and spine tingling sensation more videos try to stimulate more than $260.00 or uploaded each day many viewers say they find them relaxing. this is 34 year old you tube or dennis holder in his videos mostly eats. guys this freak. who drives previous business and comedy you tube channels didn't really take off. by eating on camera got him a following his videos last roughly 20 minutes people watch him eat to help them fall asleep as a body for 24 seconds while 20 years ago i couldn't have imagined that you could watch other people eating and find it relaxing because most people watch it to relax sometimes i find this combination

a bit bizarre because eating noisily is still frowned upon in the western world that's why i find it bizarre but really funny that's why i'm sticking with it. they are more videos have been around since 2010 but search inquiries have tripled since 2015. believes interest will continue to rise his top videos have over 90000 views clips that show him eating german classics like sausages are most popular and they help him stand out from the crowd. you can see it in the you tube analytics many new scriber is find out about me because of sausages here in germany we're famous for our sausages and i've already had comments like wow your sausages must be made of plastic they make such a snapping noise. but it's not. the advertising industry has discovered a s.m.r.

videos as a marketing tool firms like kentucky fried chicken. and german hardware store chain horn use them some last up to 40 minutes. in the world of a.s.m. our food videos solids don't tend to go down such a treat hearty fatty fare is the real click bait totals channel which has been up for 2 and a half years has 17000 subscribers and no us counterpart has reached out to him so lots of you if you want your channel to grow on you tube cooperation is pretty important i made a video with someone from the us. she has around 700000 followers and obviously some of them will end up viewing other videos of mine look at your i do work with. denis hodell has acquired hundreds of extra followers through the collaboration he hopes he'll be able to make a living from his channel. next heathrow's.

sleep. don't sleep just yet sound and music half long driven technical innovation one of the latest and most popular online platforms is take talk video sharing app can be the gateway to success for musicians but it also collects a lot of user data still nothing stands and the way of progress. well look. with many snippets like these to talk has sent the music world into a spin. the app allows you to music videos and. dancing singing you can do anything with it. with almost 740000000 downloads and

29000 the talk is now the world's 2nd most popular. for. talented musicians it offers a huge opportunity like a 24 year old rapper from braman his song over those went viral on the platform. the guy contacted me and instagram and said hey your song overdose when we could leave viral and take talk. wasn't really on my radar so i don't load it and saw 30000 videos with my song i got thousands of inquiries from labels and it broke the 1000000 mark on spotify. 600000000 views on take talk and 6000000 plays on spotify it was snapped up by

universal music now he's hoping to match these numbers with his new song. i used to release something every 2 or 3 weeks because the didn't really need to be perfect. when i finished a song i just wanted to get it out there 2 or 3 weeks later come out with the next thing. but now i. some quality and valid takes a lot more time than. only a handful of other artists have achieved similar favors. acts with old town road. blanco brown with a get up so there are. they all went viral on tick tock and became stars. i really would have liked to talk to someone at a big music label like warner or sony because surely they must be looking at to talk to increase their digital sales no one buy c.d.'s anymore but sadly they

weren't really open to discuss their strategies so instead i asked around in the german music industry association. then i. went to new player appears on the market it's often a small startup that finds a new and exciting way of distributing music then people meet and talk about it. everyone wants to be the 1st to really grasp what it's about companies get very interested in it. and then the market has to agree on a price because music has a value and a price and for music companies digital earnings have become the most important source of revenue. and that's why they're defending it. and music industry 1st started making money from streaming in 2005 and profits continued to grow 10 years later turnover had reached 2600000000 euros. it was

almost as much as all other music formats put together. digitalisation isn't something that you would cheat once and for all and then say that's done we've gone digital it's an ongoing process we live in a world where people are now thinking about how to link virtual reality and music or expand the possibilities of music listening there are still many avenues to explore. for the moment the latest digital craze take talk seems stoppable. that's despite cases of political censorship and fears about chinese government access to user data. there are actually 2 versions of to talk and one is only for china it's called. stricter censorship. in the rest of the world.

talks owner is testing its streaming service in india and indonesia in 6 days it had more than $100000.00 downloads but doesn't want to produce his music specifically for digital platforms. of course you can create songs made for tick talk with a short and snappy intro or hard fact beats but i think you can get any song or vibe across on tech talk. i don't tailor my songs to words when i hear a beat i like i take it and make a song out of it. it's that simple nowadays. i wonder what betov more value would have done with a tool like tick tock but then again the music they composed was meant to be played in concert halls designed to carry the sound all the way up to the gallery but one

thing is still true today the right sound makes all the difference. of busy more with stores than shop is and they make plenty of noise it is pretty loud in general and there's room. it's too loud too much sound is reflected for me it feels overwhelming. to work noisy listens for a living a physicist advises builders an architect on all things acoustic for example on how to lower noise levels. in a historical context people always interpret noise as trouble right something's going on dinosaur is coming or a volcano is erupting it causes an instinct to flee to kick around when it's really noisy we have these associations with pressure with

a stressful situation. syria airport in switzerland is pretty noisy at least for the people who live nearby but inside all is calm and quiet acoustics were taken into account in the airport's design the key concept is isolation there are several layers of glass built in here one after the other and taken together they provide a very high level of sound proofing inside you really aren't subjected to any adverse effects from the noise levels you'd hear outside. but what about the more than 30000000 people who stream through the airport every year surely they make a lot of noise. the ceiling is clouded with sheets of metal and some of them are perforated those perforations allow the sound waves to be absorbed reacting to. the quiet atmosphere pay solve the more comfortable passengers feel the more likely they are to open their wallets. and like many other factors in airport planning

acoustics play an important role in security. we have a loud speaker system that 1st and foremost has to issue clearly understandable announcements this device here represents the human ear. or. how well current nouns mintz be heard there are ways to measure it and operating permits for an airport is only issued when it meets criteria set down in what's called the speech transmission index. in airports the goal we shoot for is 70 percent when you measure here you see that the value actually exceeds that by a little bit given. syria airport is just one of noise projects he's also been involved in planning cutter's national museum as well as a stadium in brazil and a concert house in israel. the field of acoustics is booming

demand for expertise is on the rise in. this i think that how a room is perceived has grown an overall importance in the last few years visual characteristics still have to be harmonious there's no question that still an architect's primary business but air quality temperature and acoustics are also now key aspects of room design. this is especially true when music is involved. in the past ok stations had to calculate complex models a concert. but today computer programs can tell them what a performance will sound like from any seat in the audience before construction even begins. to militarize will become

a simulation programs that are used everywhere by acoustics experts nowadays have been around since the 1990 s. and there are certain acoustic book and so there's plenty left to do in the world of acoustic design. our resident wise enough to guess it is important to take a true break during the working day and he demonstrates the benefits by heading to a tranquil refuge far from the office. can you take care of their and they're. not sure i can. conference time. i could take a look at their so i called you back here this needs doing this has to be finished a.s.a.p. . they all want something and now i could care for him. what's

this ride i call back. got up too early i only have breakfast standing as usual. as soon as one thinks down another is waiting that's how it is all day long you need a break but not in the lunchroom you contradicts that. on that and this thing turn it off really off. go off line get out of the office away from your colleagues gartside kind of call. yourself 3. cents your body be present. and be grounded for a moment. that's

good you can do that anyway. no you say the company will collapse. no it won't but you will if you never stop. take a break. the whole day has been like this i don't know why it's not my fault. bit of peace and quiet away from the office excellent advice well that's all for now from me and the rest of the my team thanks for watching.

mean. to the point of a strong opinion it's a clear position the international perspective says. can germany succeed where others have failed in brokering a political solution to the long running conflict in libya chancellor merkel says last sunday's conference here in berlin was a 1st step to speech have a chance find out on to the point. to the point of a joke 30 militants on doug ready to go. it was once a paradise. today it's a toxic drugs a hostage situation mentioned tunisia is the filthiest river in the world.

the main computer the international fashion industry i. can assure you i'm still the same. morons most common in women in 75 minutes on p.w. . here i am picking. the closest place to hell you just want an ignorant. nice cheese and keep thinking. i want dollar story. because a. must. leave. starts january 27th on d w. every 2 seconds

a person does forced to flee their home nearly 71000000 people have been forcibly displaced. the consequences. disastrous our documentary series displaced depicts dramatic humanitarian crises around the world. forgetting when i didn't go to university to kill people that i don't know or to have my boss come to me and tell me to kill someone having in many and if i don't they'll kill me. with their lives and their future so they seek refuge abroad. scares me the most about this state to rise is that someday we won't even see the relief. but what will become of us who stay behind it's if my husband went to peru because of the crisis. if he hadn't gone there we would have died of hunger. let me down down. just
