entrance to the camp that all trains kimi and we've been very involved in you. know since and we didn't go into new areas and. i love your story. because i'm bored. most. easily. stores january 27th on d w. from. what do you hear music kids playing a neighbor drilling raindrops hammering against the window your own heartbeat 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 mate good 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 are quiet but estrogens 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. in between we're going to sit at the mating call of a stag. this country or a tiger or whatever is not the chirping of a sparrow. office mature sound like that does something to a driver or men are said to meet at your bellowing noise that signifies. time of greatest or does this buzzing sound zen 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 i'm a power to you don't you don't the challenge is to develop that power for electric cars the shawls we elect to move iti. 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. feel good does it not matter too that's just part of it for many people with big engine big sound great sound bite. 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 electrify 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 kind of. sound designer just want to shape the experience of those inside the car as well as outside it's also about branding. thus far by 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 over now you can fake everything so you keep wondering does anything actually sound like what it really is. driving pleasure

reliability safety all that has to be suggested by the sound of a car. 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. to vegas ounces. so when an electric car set softened the future it might sound something like this. but sound designers 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 car sound like a flying saucer for example or anything else one might care to dream up. we could all get rather interesting. description i still consider the sound. well sound is everywhere and affects us whether we realize it or not i mean you sound pleasant and soothing like birds singing. laughter. and of course iraq sling when none now of us off far far less appealing sounds like silverware scratching across a cotton play to a screeching child across

a block vote 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 out is never switched 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 and music influences our subconsciously triggering emotions but it is a 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 the n.p.r.'s 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 hear classical music while will only pay an average of $1.00 euro $95.00 if pop music is played but we don't buy more bottles. from playing sounds people rubbing their hands together or drumming on tin cans accompanied by whispering voices. some people say any s.m.r. videos on youtube calm them down or make their scalps feel all tingly. some fast food outlets or do it yourself schools have already used these kinds of videos in advertising campaigns. and by the way researchers say dairy cows produce

7.5 percent more milk when beethoven is played to them than when no music is played . whereas popular music for example seems to cut normal yields by some 2.5 percent . another study indicated that sounds can even change the way swiss and the target is ages which is 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 what productive and sound can wholesome be used to appeal 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 s 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. listening a yes m.r. stands for autonomous sensory meridian response it's that pleasant scalp and spine tingling sensation that the s.m.r. videos try to stimulate more than 260 year 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. to preach this earth. who drives previous business and comedy you tube channels didn't really take off. with day but even on camera got him a following his videos last roughly 20 minutes people watch him eat to help them fall asleep that's what the folks want to show

a force that can do what 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. 02 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 nooses 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. i hear. and german hardware store chain horn used them some last up to 40 minutes. in the world of more food videos solids don't tend to go down such a treat a hearty fatty fare is the real click bait total scam which has been out for 2 and a half years has 17000 subscribers and no us counterpart has reached out to web some of its a few 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 your i do work with. dennis

hodell has acquired hundreds of extra followers through the collaboration he hopes he'll be able to make a living from his channel. next. guys. 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. ringback lol. with many snippets like these take the music world into

a spin. the app allows you to music videos and. dancing singing you can do anything with this. with almost 740000000 downloads and 29000 to 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 overdose went viral on the platform. the guy contacted me instagram and said hey your song overdose when we could leave viral on to talk 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 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 it 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. focus on quality and that takes a lot more time than. only a handful of other artists have achieved similar famers like x. with old town road. 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 the 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. when a 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 their 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 continue to grow 10 years later turnover had reached 2600000000 euros by 28 it was a burning almost as much as all other music formats put together. digitalisation isn't something that he 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. more expand the possibilities of music listening there are still many avenues to explore. for the moment the latest digital craze take talk seems. 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 subject even stricter censorship take talk we know in the rest of the world take talks owner by testing its streaming service in india and indonesia in 6 days it had more than 100000 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 of fat beats but i think you can get any song across on tech talk. radio i don't tailor my songs to words when i hear a beat i like i take it.

it's that simple nowadays i wonder what beat the idea 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. the more with stores in shoppers and they make plenty of noise. pretty loud in general and there's room. it's too loud too much sound as reflected for me it feels overwhelming. durk noise listens for a living a physicist advices builders an architect on all things acoustic for example on how to lower noise levels. in a historical context people always interpret noise or trouble right something's

going on dinosaur is coming or a volcano is erupting it causes an instinct to flee to cape town when it's really noisy we have these associations with pressure with a stressful situation. searing airport in switzerland it's 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 of facts 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 colonel ounce 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. serious 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 concept house in israel. the field of acoustics is booming demand for expertise is on the rise still in. this i think that how a room is perceived has grown in 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 mill and soon will become a simulation programs that are used everywhere by acoustics experts nowadays have been around since the 1990 s. and they are certainly used by architects in planning large scale project but in many other cases for example in planning restaurants the acoustic aspects are still largely unexplored acoustic. and so there's plenty left to do in the world of acoustic design. our resident wise enough to guess as 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.

to see if they like we'll 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 take care of it i mean. what's this right i call back. got up too early i only have breakfast standing as usual and. soon as one thinks down and others waiting that's how it is all day long you need a break but not in the lunchroom you can't relax that. on that and this thing turn it off really off go off line get out of the
