yes it is all its way to bring you more conservation. how do we make cities greener how can we protect habitats we can make a difference globally genius or a mental series accountable $3000.00 on t.w. and online. cutting. was extinct is makes sense to me was stop. ok wouldn't it be great if you could silence noise just like that we all know this only works on t.v. let's face it if i would sit here every single day i would presume to be deaf or

sick in any case especially road traffic noise is a risk to your health and well being on headaches dizziness and tonight is just some illnesses that can be caused by noise. a moment of quiet nothing but some blissful. unfortunately. our everyday lives are usually different when confronted with all sorts of noise 24 hours a day closing out isn't an option sounds become noise when they disturb us often when they're very loud but it's not just a question of volume psychologist dani and crystal says noise can't be described in purely physical terms. noise isn't an acoustic property it's a sensation but it is related to the acoustic properties of the sound. the louder the sound the more likely it is to bother me so it also depends on the situation.

if my favorite bands playing a concert i won't mind it being really loud but if i want to sleep my favorite band hopefully won't be playing in my living room an important factor is whether or not you have control. a sound that i can turn on and off is less likely to disturb me than something like street noise or aircraft noise because i can't control those. noises in our environment and especially become a problem when we're completely at sea it's no wonder that lots of people are affected by traffic noise and noise can cause illness even if we've become so used to a soundscape that we no longer consciously perceive it noises can still affect our health. for example scientists are studying the connections between noise pollution and mental illnesses such as anxiety and depression. and noise pollution is

a huge factor in stress especially if it persists for years. we've just completed a new study where we were able to show that noise pollution can predict the onset of anxiety and depression even 5 years later as well as insomnia for. but not everyone can choose where they live and work for many the only option is to cope with noise as best they can put it in fear. and i would advise people not to limit themselves because of concerns about noise but to continue with their activities and do the things they enjoy stress up to pawn that's an important way of reducing stress and then you can avoid the vicious circle of noise pollution and possible anxiety or depression that heartened. these days away seas of quiet a rare and valuable precious. the important thing is to seek them out. as the philosopher friedrich nietzsche remarked the greatest events are not our

noisiest but our stillest hours. underneath the next spring at the technical university of berlin since january 2019 he works at the institute of fluid mechanics and technical excuse to research his noisy face and noise assessment among other. high halo over the period how i felt i see through as the media what's he doing here i measure that the level also your traffic noise at this very busy street there so it's quite noisy isn't it yeah it's expected it's. much lower than 70 to be an average so it's very loud so it would be very appropriate to live here yes i would like to have me too ok so what about if you go to something more quiet great ok. it's a very very busy street it's very noisy is there

a difference between noise and just sound yes there's a difference and. it's noises on want to know as if you think it's in appropriate detail as noise and therefore it is a psychological phenomenon it is not the physical event it's in the printed auditory event this makes it sound to unwanted noise sary depends on my perception of what i do about this. yes yes and therefore it is difficult to measure if such a device unwanted noise because it is you is your perception. a lot of engineers tried to reduce noise from cars but it's still noisy so so why is this there's a simple reason because we have so many cars and on our roads so i think of it as a single car is quite a dent in the parsed but we have much more cars on the roads

a day off for the road traffic noise is quite high in our cities so but when you take a look at all the capitals in this world to me that cities are getting bigger and bigger and more mobility more mobility so can we do anything about the noise there are some approaches to promote develop being in cities to reduce noise on the technical side but also to offer something less torque to places like parks green areas because we can observe that it is quite quite beneficial for the for the health and life satisfaction for people living in cities but be divided say well i love this noise here it's great it's a booming city and i like to watch all the cars and the like it's here and there's still some net negative effects i mean. i would say it helps if you have a positive thinking it and a positive attitude towards the noise over city then it might decrease to

a certain extent potential health effects bought. our ears. we are always listening and therefore we cannot really adapt to noise it always stress therefore you can't avoid any health related risk. in with a think that the the so nice all and even if i like the lawyers even if you like the laws better it's quite simple if you listen to loud music over a long time then of course you will. have for hearing impairment often soldiers it's not exposure so let's 1st have a look at how our ears work and how they do this 24 seventh's. this is how dangerous prehistoric times you shut your eyes for some while undressed him and not even knowing it you're on the dinner menu for the competing species. bumps. that's all it takes despite sleep mode the ia is wide

awake it's registered the telltale sound and in a flash it transmits the signal to the controls and has a moment later the adrenal gland releases the stress hormones adrenaline and nor adrenaline they activate the unarmed systems in all the important organ. not immediately steps on the gas to increase the body's oxygen supply. blood vessels constrict blood pressure bryce's digestion is now of minor importance it gets decoupling from the blood stream maximum blood supply has to go to cause the body needed for survival right now the muscles a crucial. a rude awakening that at least the internal systems are already running at full speed so phyto flight in this case best to make a speaking exit. if you have this case but now it's time to replenish the lost

energy. after a short delay the stress hormone cortisol is also taking effect fat from the body's deploy. it's being mobilized. in the liver sugar is manufactured and released into the blood. caught his arm and shows that we don't run out of fuel when fleeing from danger it's an ingenious survival strategy for emergencies. but ever since we traded life in the wilderness for roads houses and traffic there's been a problem the alarm system that protected us by peds from saber tooth tigers for thousands of years now seems to have run its course. even though modern sources of noise can be annoying they rarely signal life threatening danger. but our alarm systems still react in the same way beware of saber tooth tigers the path of fight or flight. so stress hormones are released unnoticed during sleep and

particular cortisol levels a permanently elevated when there's continuous noise we get into a fight or flight mode our blood pressure goes up and energy is quickly made available in the blood. even if it isn't needed. in the long term that can cause health problems too high levels of sugar and liquids in the blood and hypertension can be precursors to cardiovascular disease. sic windows are the only permanent solution to help us sleep soundly and to give our in a a gnome system some rest. even in our modern world there are some loud noises that are somewhat outdated warning system should respond to when it comes to distinguishing between annoying and life threatening sounds. human evolution still has a long way to go. we've got something

more listen closely. andrea garcia is getting ready for bed but 1st he setting up a gadget that will measure the noise levels in his room because it's going to be a noisy night while he's asleep he will be exposed to the noise of airplanes flying overhead. tonight it will be turkey planes tomorrow night 60. 8 andrea tries to sleep as best he can. he's in for a restless night. people who live near airports have to put up with a lot of noise often until late at night and then again from early in the morning we're. almost mental has spent 7 years studying what noise does to our bodies the cardiologist is especially interested in the noise of airplanes at night which many

people struggle with. the idea of studying aircraft noise at night is based on major studies that have shown clear link between insufficient or interrupted sleep and a greater risk of cardiovascular conditions so heart attacks strokes cardiac arrhythmias or cardiac insufficiency. could too much noise be the cause the next morning andrea garcia goes to the clinic to be examined the doctors use ultrasound to evaluate the blood flow through his arteries that will show how elastic they are as a result of his poor night's sleep his arteries are less flexible. because andrea was healthy his body would repair the damage but that isn't the case with everyone . they say i have coronary heart disease for example and i'm exposed to aircraft noise at night then the condition of my arteries deteriorates and before then i have to assume that this noise related deterioration of my arteries will

lead to more heart attacks or cardiac arrhythmias heart failure and so on as for how to use them. so how come noise affects our blood vessels. that's something thomas mental has been investigating in mice when the rodents are exposed to the sound of airplanes their bodies produce more stress hormones they also suffer inflammation of the arteries because free radicals seen here and brown are formed in their cells. that you see in those. 100 garcia has now had a 2nd night of aircraft noise again he is not slept well. the cardiologist want to know whether his body has got used to the noise in which case his arteries all to be a little more flexible this time and less affected by his lack of sleep but the ultrasound shows the opposite to having the i was confronted with.

we've discovered that once an individual has had exposure to noise at night the deterioration of the arteries is considerably worse the following night stick up this heist in other words your blood vessels don't get used to the noise the damage inflicted on them is actually more pronounced. studies have shown that aircraft noise at nice not only damages blood vessels but also the brain causing it to age faster the doctors have discovered that memory and the ability to learn are impaired as a result. mice exposed to aircraft noise in this study for example were less able to remember where their rescue platform was in the water. the results of the study can be transferred to humans. we can start speaking the point is we know that children who live near airports develop a learning ability and memory more slowly and we can get one for our research results explain the cause of this phenomenon very well. people constantly

exposed to noise at night are at increased risk of high blood pressure atrial fibrillation strokes and heart attacks depression can be another resulting factor the scientists are now working on a drug designed to reduce the harmful effects of noise on the body. even though getting a peaceful night's sleep on a regular basis would of course be the best medicine. well i do love my headphones i have to admit and many young people are wearing headphones all over the day this is a problem. this is a problem in fact see that we have. gotten persons already showing some kind of hearing loss and this might be due to the extent of hues of. the biases

and the consumption of music and other stuff close to the ears because we have been high level at that your drum and this will cost them a hearing impairment after several years is just because they just pump up the volume that it's very loud insiders and not a problem as well but have fans there 1st of all the allow this of all you is a decisive factor as well as of course the duration how long. do they listen to such sounds and is this loudness and so is the expression of the doe's the loudness as well as the exposure time and we have to be aware that it is very close to the ear and so we have already very loud. levels at your drum but honestly i do have to turn up the volume because when i'm sitting here in this noisy road next to me i won't hear my music unless i just pump up the volume. gauge indicates how

dangerous it is so we have to really to mask the environmental noise in order to hear the music or your content and this shows what kind of volume or loudness we have at that your drum so it's even much louder than the usual ordinary of my mental noise. there's an app for that you can always do measurements with a modern smartphone so this is an app called ear action and you can just press the button and then you can see how noisy it is around you so as it is that of any value. i think it can be very valuable for young people in order to. assess the risk of. noise assault then they can measure and get a number and can decide what side i'll buy that it's too loud so i need some recovery time for my hearing system because if you have for. 80 or $85.00 to be then. you know it's might be critical law exposer time for my

hearing system for my hears so otherwise you can just damage it yes yes and such f. can show. off their noises around and then you can decide where maybe to leave. me. if you know. anyone looking for peace and quiet has come to the wrong place a flat ground engages all the senses a sea of lights for the eyes sweet treats with a tongue and a symphony of sounds for the ear. but what does it feel like when something goes wrong. as it has guessed i mean humans kiersten i was suddenly hit by a loss of hearing and now everything sounds much dollar but i'm slowly getting used to that i do still hear things like the clatter of the roller coaster.

kinston is now almost completely deaf in her right ear. the sudden hearing loss was probably caused by stress. to her. the world now sounds much less vibrant. she can still hear well with her left ear. but one air alone can't do the work of 2. for example she can no longer determine exactly where the sound is coming from. some couldn't hear you need both fires to hear well that allows you to recognize sounds and also to hear where there might be a source of danger that's why it's so important to look after your ears off the

passage. with only one ear working properly spatial hearing is in pat i'm not a common problem is tenet has a constant ringing in the years. it's usually brought on by prolonged exposure to loud noise. when our hearing is simply overwhelmed we can start to hear a certain sound even if there's no real external source it's usually a kind of whistling and it's always that day and night. the stick it's a torment and there's no guarantee it will go away it's best to learn to live with it and that. people suffering from tinnitus hear something they don't want to hear while those who are deaf hear nothing at all. impaired hearing lies somewhere between these 2 extremes and it can have many different causes.

the main courses are stress illness and excessive noise in the environment. but hearing also declines as we get older. children can hear frequencies of between 16 and 20000 hertz grown ups gradually lose the very high frequencies. the more our hearing range diminishes the greater the impact on our every day life . sound frequencies are to the ear what colors are to the eye the fewer we perceive the less information we can register. saying oh it impaired hearing can affect any pitch from the mono it's to the high notes such as birdsong or children's weiss's or the screeching hear in the background as i said yeah. the ability to hear a wide range of sounds from low pitch too high is key to distinguishing speech from

background noise that becomes ever harder as the range diminishes at some point voice and noise become indistinguishable everything melts into what blur of sound. as a rule when one's hearing gets that bad the doctors can't do much to help. so we need to protect our ears as best we can. if we're plagued by persistent stress keep tormenting our ears with nasty no. we risk losing our hearing altogether. we still in berlin but somewhere less noisy so it's important to give us some rest yes definitely. b.c. in our study said it is quite beneficial colleville being unsatisfaction to go to quite areas and relax there that is a very good thing also for our human hearing but also for the body and or health

and i mean this is less noisy in the place next to the street but there's still some noise coming from there you can give it people are working so that annoys me a bit but if i would sing loud i would hear some great music it wouldn't annoy me at all is this a typical human reaction yes i would say yes because if you think it is unnecessary it's voidable such noise then you have a very strong. emotion and strong annoyance reaction and it shows it's not the physical event itself it's that whether it's necessary or water bill or not and this really drives also the reactions and responses when you take a look at daily life so what can you practically do to protect your ears and to get some quiet run the day ok one important thing is to go to such places

and relax and you can also contribute to a quite the environment by buying quite products like a quiet printer or alone more or some. things you use in your daily life. this can really help to have acquired a environment you can benefit from it and others as well so it's not all about planes and cars and industrial noises and yes you are right it is also a vault. noise from neighbors we see much more complaints about the noise from neighbors no days that might be due to using increasing noise awareness that we know about the health effects. noise so much more critical and sensitive to such analysis and if you be considerate to other people respectful of people if you buy products then you can contribute to a quite violent it's not only

a technical solutions for making. traffic noise it's also our behavior so in my own personal noise can be intrusive definitely yes definitely so in particular if people think it's unnecessary it's unnecessary then noise then people see strong reactions to it so what you could do for quiet environment is. very quietly and. in good shape for your weekly health. covers many aspects of health care. what's new in medical treatment nutrition fitness and beauty. we discuss these topics in depth with specialists and give you the chance to pose your own questions so do get in touch through.
