What are bodily symptoms of increased CO2 levels?
Increase in confusion, and finally loss of consciousness, coma and death (with high enough CO2 levels).
What is well loss?
Well loss is the step difference in water levels inside and outside the well. It is due to energy losses across the well screen.
How are chemical elements most often transferred between different topic levels?
their gain or loss of electrons
When are 2 amino acids linked by a peptide bond?
two tRNAs pair with neighboring codons on an mRNA transcript
Where are chromosomes located in hearing impairment?
Non syndromic hearing loss (loss without other clinical problems) should be addressed. Non syndromic hearing loss is more common and autosomal recessive accounts for 80% of losses whereas autosomal dominant accounts for about 20%. Less than 3% of losses are due to mitochondrial genetic faults and X linked chromosomes.
What is the lowest level of noise that can cause hearing loss?
The lowest level of noise that can cause hearing loss is 85 dB. Prolonged exposure to noise at this level or higher can cause permanent damage to the tiny hair cells in the inner ear which are responsible for transmitting sound signals to the brain. In general any noise louder than 80 dB can cause hearing loss so it is important to protect your hearing when exposed to these levels of sound. Noise levels below 70 dB do not typically cause hearing loss. Noise levels between 70 and 85 dB can cause hearing loss with extended unprotected exposure. Noise levels above 85 dB can cause hearing loss with shorter unprotected exposure.It is important to be aware of the noise levels around you and to take steps to protect your hearing. If a noise is too loud wear hearing protection such as ear plugs or ear muffs. Additionally it is important to take regular breaks away from noise to allow your ears to rest.
Permanent hearing loss can occur when one is exposed to what?
Hearing loss by noise exposure occurs when the cochlea or Inner Ear is exposed to excessive noise levels that can cause temporary or permanent damage to ones hearing. We use a baseline that sound levels over 85dB will cause hearing loss and that hearing protection is manatory when exposed. Cell phones, televisions, personal entertianment devices, lawn mowers, power tools, sports or entertainment forums all can easly cause hearing loss. Everyday sounds you find outside can also cause hearing loss and we call that noise pollution. Noise exposure will be the leading cause of hearing loss in people aged between 20 - 60 years old. Noise levels that cause hearing loss can be long term or short term and is determined by the intensity of decible range (loudness)and frequency versus time exposure to that sound. Best described it is your exposure time against the intesity of the volume levels. You can be exposed to low levels over longer periods and shorter period with more intense levels. Very much like being exposed to radiation. We can all be exposed to radition with temporary or little effect or be very harmed by it. Long term exposure to low doses or short term doses at high levels can extremely harmful. So the longer you are exposed to intense sound the more likely you will get hearing loss and most likely permanent loss. It may take 1 second as a jet fighter takes off or 20 years listening to traffic you can have noise induced hearing loss. Anyone that has been to a rock concert can remember the "amplifer hum" after the concert and feeling deafened, that was hearing loss due to noise exposure. Hopefully your hearing came back but it was a signed that you damaged your hearing and may come back later like exposure to the sun to haunt you. We have determine that noise levels measures at 85dB or greater can cause hearing loss. We us a sound level meter to measure or weight noise by peak levels or long term levels by intensity and also by frequency. We can determine if the sound levels are dangerouse and recommeded protection. The human part effected is the hearing nerves that cannot be replaced, so most noise induced hearing loss is permanent. How can we determine noise exposure has caused a hearing loss? Ususally , client history current and if possible past hearing tests . There is in most cases a distinct shape of hearing loss in tested frequencys that can effect one ear or both ears and previous hearing tests are available we can see if and what changes have occured. What can you do about it? Not much except possible use of a hearing aid to help with the hearing loss and protection what hearing is left. There is little medically at this time that can be done as far as repairing the damage. So allways use hearing protection, turn down your IPOD and cell phone and just be lucky you are not driving in the car that you can hear playing music a mile away. There is available. There is enough available hearing protection the can be specific for your hearing needs and uses so use them.
How has noise induced hearing loss been reduced?
Laws that require protection from loud noise in the workplace have achieved substantial reduction in noise induced hearing loss.
What are affects of noise pollution?
loss of hearing (from excessive exposer to extreme noise pollution) and bags under the eyes (from loss of sleep :P)
What are negative effects of transportation technology'?
- global warming (Antarctica - rising sea levels) - illegal immigration - noise pollution - visual pollution - loss of earths natural resources - injuries - deforestation - loss of natural habitats - wars for oil - social issues
What is the insertion loss and noise figure of your filter?
insertion loss the loss that occur the insertion of a device in transmit ion line or fiber .
Diseases caused by noise pollution?
uhmmm...... loss of hearing?
What are the signs of a blown turbo?
Unusual noise, significant smoke from the tailpipe, loss of power and loss of boost.
What is excessive environmental noise from planes autos and industry?
Excessive environmental noise, also known as noise pollution, is the presence of high levels of noise from various sources like planes, automobiles, and industrial activities that can have harmful effects on human health and the environment. It can lead to stress, sleep disturbances, hearing loss, and overall decreased quality of life for those exposed to it. Measures to mitigate noise pollution include soundproofing buildings, implementing noise regulations, and designing quieter transportation and industrial equipment.
When was noise discovered as a ill health problem?
Noise was known to cause hearing loss as early as the 1930s and possibly before that.
What is the main causes of hearing loss?
Prolonged exposure to loud noise is the leading cause of sensory hearing loss.
