Type: suchowychAparaty hearing loss Decibels or percentage December 2000, Dr. Neil Bauman Revised February 2003 Question: From time to time, I see people, he wrote: "I have 78 hearing loss in the right ear and 95 left." What is the percentage mean I thought the sound was measured in decibels dB, and not the percentage If this is the case, what percentage is 115 dB R. D.Odpowied: Great question. You have good reason to be confused, because you can not identify decibels as a percentage no matter what anyone mwi.Decybeli vs procentNatenia sound is actually measured in decibels dB. There are two reasons why you can never identify decibels as a percentage. First, the decibel scale is open-ended, that as the Richter scale used to measure the intensity of earthquakes. To calculate the percentage you need to know the value of the maximum possible. In both of these scales there is no cap on the maximum value. Therefore, one can not calculate the percentage. Any such attempt is only a few meaningless gibberish! Second, the decibel scale is logarithmic, a percentage scale is linear. The numbers that appear similar are very different meanings. They are as different as trying to compare apples to elephants! When people unconsciously Talk about having a 50 percent hearing loss, they probably mean that they have a loss of 50 dB. Where did the idea that we can measure the percentage of hearing loss Here's how Brad Ingrao, an eminent audiologist, wyjani.Aby measure sound intensity audiologists measurable need to do mathematical calculations that are so strange that 20 20 26 dB SPL. "To a scale that makes sense for most people including our audiologists knucklehead, otherwise the equation is used to convert the volume using the sound pressure level SPL scale to the volume HL scale that goes from 0 dB HL normal level to 120 dB HL pain. If we forget about hearing loss greater than 100 dB as most people do not, we get 0 dB to 100 dB as useful dynamic range of hearing for the average "normal" ucha.Poniewa doctors and audiologists tend to under-estimate the ability of the patient to understand such things or do not understand it themselves, erroneous notion dB evolution. "There you have it folks. Apparently, health professionals, we are too stupid to understand a lot, so let us believe a mistake, instead of teaching us prawdy.Moemy put an end to this nonsense now. I want to understand how the decibel scale works and why using a percentage to describe our loss of hearing is so le.Najpierw we need to understand that the decibel is not a given intensity loudness of the sound, but rather that it is the ratio of the number of times louder or soft, the sound is the sound level referencyjnego.Oznacza that 0 dB is no sound, but it is an arbitrary zero. We define it as a sound, a young sensitive human ear hears. Moreover, since the decibel scale is logarithmic, every 10 dB of sound is actually a ten-fold increase. Therefore the volume by 20 dB is twice as loud as the sound of 10 dB, but is 10 times loud, and the volume by 30 dB is 100 times louder than the sound of 10 dB. Similarly, the volume will be 50 dB 100 000 times out loud 10 x 10 x 10 x 10 x 10. In this way the decibel scale works. It is completely different from the linear scale procentowej.Teraz see the fallacy of trying to compare this "small" scale decibel scale rate. To illustrate, suppose remember, it's the assumption that we're doing here is completely wrong that 0 dB is equal to 0 percent loss of hearing and 100 dB loss is equal to 100 percent. This would mean that 50 percent is equal to 50 dB of hearing loss, right Wrong! Not by a long shot! 50 percent of hearing loss will be equal to, believe it or not, only 3 dB loss! Looking at it another way, 50 decibel loss is only half as loud as it will be a percentage scale, but it will be only one-thousandth of a percent so loud! Another example. I have a 70 dB loss. This is not equal to 70 percent of the loss in any way. In fact, this means that I can hear the faintest sound should be 10000000 times louder than the softest sound a person with normal hearing can hear. One in ten million is definitely not a 70 percent loss, but you will lose 99.9999999! Quite a difference, right Now you can see why we can not use percentages when talking about our hearing loss. They simply do not identify. They are absolutely ridiculous! Percentage used to describe DyskryminacjiMimo that you can not use percentages to describe our loss of hearing, we can properly use percentages to describe our ability to distinguish sounds. To determine our ability to distinguish between words, our audiologist adjusts the volume on our volume. Then I have to listen to us a list of words and repeat what we think we hear. We have the right number, in terms of percentage, it becomes our result of discrimination. Therefore, if you understand 80 of 100 words in my right ear, my discrimination is 80 for the ear. I may have a completely different outcome for my other ear. Therefore, we can accurately describe our ability to understand what we hear as a percentage. A person can correctly say that the discrimination is 78 in the right ear and 95 in the left ear. But it has nothing to do with the severity of hearing loss as our takich.Niepenosprawno Percentage and suchuJeli hearing loss as a result of an accident at work, is the formula that is used to calculate the percentage of pension for which they may be entitled. Do not get involved. This is not a hearing loss is expressed as a percentage. On the contrary, this formula calculates how much the degree of hearing loss allegedly affects the ability to remain employed at full wynagrodze.Na example, plunking your level of hearing loss to the model can give the result of 75. This means that with a hearing loss, you may be entitled to a 75 pension. Again, this is not your average hearing loss is expressed as a percentage. If you are interested in how to calculate the percentage of disability for hearing loss, see my article you can read the "How much are you worth as a hearing-impaired person". Prioritizing Our loss suchuPracownikw health care hearing hearing classification into several categories, such as normal, light, mild, moderate, medium, heavy, serious, deep and dull. Not all of them use all of these categories, nor do they all use the same range of hearing loss in each of them. In the past, the most common is a simple skal.Proste Classification Hearing Hearing ThresholdNormalna suchudo 20 dBMild loss suchuOd 21 to 40 dBredni loss suchuOd 41 to 60 dBCikie damage suchuOd 61 to 90 dBGbokim niedosuchemponiej 90 dBDzi, studies have shown that even hearing loss only a few decibels can cause serious hearing problems. As a result, many health professionals are refined care hearing this scale in order to better reflect this reality. Please note that these ranges are arbitrary and may vary slightly between authorities.

If you have a typical "ski slope" hearing loss can be described as "I'm 30 dB loss at 500 Hz, falling to 100 dB at 4000 Hz." A more general way, but still true, that would be described as "I have a mild loss in the low frequency range, falls into a deep at higher czstotliwociach.Nastpny best way to describe our hearing loss is the average of four frequencies that carry most of the speech information to arrive at a figure . use the following four frequencies 500 Hz, 1000 Hz, 2000 Hz and 3000 HZA And the average hearing loss in the frequencies derived from one drawing. However, this method decreases, if only we have some hearing left at very low frequencies. By Frankly, it is not right to take the average of our best and worst form. This can give a very bad impression of our losses suchu.Jeli want a very simple way to describe your hearing loss, the most accurate and easy it means you have either mild, moderate, severe or profound hearing loss. Your audiologist can say which category of hearing is generally in. Remember, you can be mild at low frequencies and deep in the highs But simplification can be reasonably reflect the practical loss of hearing in one of these categories. is much more significant and much more accurate than trying to use a percentage point.
