live from berlin i'm brian thomas with the entire news team thanks so much for being here don't forget there's more to website but for the. first day in school in the jungle. for 1st clinging listen to. as grand the moment arrives. joining a ranting on her journey back to freedom. in our interactive documentary tour of the regulating returns home on the d w don't come to tank. the blue planet our world. we tend to describe its beauty in terms of what we

see and treat our site as our primary sense. but in recent years new research has pointed toward the importance of hearing of the sounds of our world and how we process them. hearing it seems is more important than we thought. some even believe it's the key to our futures. music is inbuilt within our d.n.a. within our genes. our society becomes faster and faster and faster we have to get information out of the environment there it quickly the auditory channel is quicker than the visual channel. this big developments happening in technology at the moment and a lot of people soon that's all about the visual but if you don't get the sound right then your sensor motion completely disappears.

so i walked to the right way going to how people react to every day sounds so i go on about the normal day icon of this lots of sounds i'm not really paying attention to little and i will be taking in my ears my brain will be taking unconscious. slee but michael just browsing the web. some aspects of the channel author

of a sense is not because we might think of his being as being something to do with speaking like i am now in communication but i choose an early warning system and that's what it's 1st evolutionary purpose. good to see you're welcome to the sound will come it's a really noisy place isn't it you would believe under these railway system most amazing sounds which will lead you about this wonderful call coffin and follow me. to my just as a listener around here just. one can hear. you

. come down maternal line boldness my. point you can see we hear. a slight back of the sofa for news on the 1950 s. rock n roll and part of musicianship reads he is going to great sound effect but he just calls by the. you know the brick is just peeping the sound here that your son

is probably spinning around inside of this curve but you have the bottom coming back and it will be also going along the top of the water and coming back again see it is amazing amazing contribution by science the mystery is how is the sun getting across it's giving around the top of the great was it just going straight and bouncing off the wall and coming straight back to you. could even be both. i think sound can be both about listening and about vibration so from a purely so physical point if you could think of acoustic ways which a vibration and they don't need someone to listen to to actually exist but actually to be of interest really you could have some observer has got to be an animal whether it's a human or a bird whatever listening to the. early

ninety's i moved from a music listener to. explore experiment. working on this topic you realized it is not really a 100 percent but the feeling of his reality existing outside of us. our brain it's all the delivering information to be needed in order to survive but you can very much money relate to your brain by giving it attention to. constant listening to the soundtrack. it's up to you how much of that sulphuric want to hear

. the sound itself can. physically. change our behavior in a radical way it can create moods that creates a physical reaction in the body the street in law is the law of this this is a this already a language but can communicate so much we never speech of actually hearing because everything what is moving everything what is living has a frequency that's a risk even if deep before we are born we have to experience of self.

one of the interesting things that i picked up on was how different the arches were i mean between them all because they all seem very similar in makeup and shape and size it depends whether focusing point as compared to the ground is above the ground and it's not really a cliff but the head you don't hit face right on the ground you get this reinforcement sign goes down an up and down and up and there's all kind of weird accused effects which you know we've all been listening to for millennia i mean this is this coast theories to. is placed in places where the echoes are particularly interesting so you can paint a picture of a figure and you stand but by and go out in the sun will come off and it will look like the person's to a sound of a person's. it's rather strange as an archaeologist. to have an interest in music because the past

is of course totally sonnet to us. we know that some of the most elaborate painted panels in the caves or similar case where he got the most dramatic acoustics. so he sped those paintings were associated with singing dancing musicality. this is a typical train or tram noise and i wonder what your sponsors to. be low enough i think i'm so you know it's really been pleasant on the ear how how calm and the theory has it is that there scraping sounds on pleasant because they sound a bit like a scream and in our brains we have a very short will sponsor mechanism to deal with danger that's what having was 1st

of evolution it was an early warning system so you'd find a lot of cities doing things like bringing fountains into squares because it gives you the sound of nature and you can do things like high traffic noise with it and of course we like the sound of nature is good for us you know in evolution returns we're used to living not in a city but out in the countryside and when there's water there's there's going to be food that's going to be what for us to drink so we naturally find a pleasant sound. and was quite curious about sound is actually sound waves a really weak from a physical point a few tiny little motions of air molecules but to us you know we have these big big emotional feelings responding to this week little force. little. for.

you. to. her. it was . the.

when early ancestors going back to be 3000000 years communicated with musicality they did that to express emotions to manipulate emotions to bill socialization ships because that was before language so we asked what was all this ability to be receptive to sounds what was all being used to have music it was it was being used for making music or of the making conversation is limited. humans are social creatures it was our hearing that enabled us to build communities

and to secure the survival of our species through evolution. the importance of our audio functions can be discerned from the moment we are born. babies are like superman when babies are born they are musical so they can discriminate between the rhythm of their native language and rhythms of other languages but more interestingly and at age of 4 days after birth babies are already crying in the stress pattern of their mother was the genes had an influence on brain structure that made us at one point musical and also able to process language.
