Babies and children are not the only ones that need hearing protection at noisy events, you do too! Keep these facts in mind next time you go to a loud arena. At 140 dB, immediate nerve damage can occurĪt events you know will be long and noisy it is important to plan for it. dB table sound pressure levels SPL level test normal voice sound levels sound units decibel level common sounds sound intensity decibel comparison chart.At 112 dB, damage can occur with only one minute of exposure.This means that when you move up 10 on the decibel scale, sound is actually becoming ten times louder. At 100 dB, damage can occur with 15 minutes of exposure To accomplish this, the decibel scale is actually logarithmic.At 85 decibels, the maximum recommended exposure time is 8 hours. In fact, for every 10 decibels of noise exposure, the intensity of the sound goes up 10 times 2. Many of us enjoy sporting events and concerts and think that a few hours of these loud noises would not be damaging. Three main factors influence the severity of hearing damage: The louder the noise level, the less time it takes for the damage to take place. Arrowhead Stadium – Kansas City, MO (2014) – 142.2 dB.CenturyLink Field – Seattle, WA (2013) – 137.6.Loud noise above 120 dB can cause immediate harm to your ears. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Husky Stadium – Seattle, WA (1992) – 133.6 dB A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB.Memorial Stadium – Clemson, SC (2007) – 132.8 dB.Turk Telekom Stadium – Istanbul, Turkey (2011) – 131.dB.This decibel chart goes into detail about the sounds mentioned above: *In 2017, the Guinness Book of World Records released a list of the top loudest sports stadiums in the world. Sporting events: range from 105 dB to 130 dB*.Sirens (ambulance, police, etc.): 120 dB.Here are how some sounds rank based on decibels: Some noises that are above 140 decibels would be fireworks (150 dB), shooting off a pistol or rifle (160 dB), and near a rocket launch platform (180 dB). It is important to note that “while we can hear more than 140 decibels, it is too painful for our ears and if you expose yourself to such a loud noise you are at extremely high risk of permanent damage to your hearing” (Alpine). Audiologists use decibels to set hearing aids to the comfort of the user on a scale of 0 – 140 decibels, with 0 being no sound and 140 being the most sound. Decibels (dB) are units that are used to measure sound level/intensity.
