With the nature of sound, when does normal noise become deafening? Knowing about decibel levels can help preserve your hearing.
The Decibel Scale Explained
Decibels (dB) are a logarithmic measurement for the intensity of sound. This means that 10dB is actually a tenfold increase in sound intensity. A whisper is about 30dB, normal conversation hits around the low 60s and a lawnmower yodeling good times at you weighs in at just under that lovely 90-point.
The Danger Zone
Hearing damage is the consequence of exposure to sounds over 85dB for an extended period. About as loud as city traffic or a garbage truck. The louder the sound, remember that it needs very little time to harm your hearing. For an Audiologist Cheltenham, contact www.imperialhearing.com/audiologist-near-me/cheltenham
Time Matters
There is about 8 hours worth of safe listening at 85db. Damage can occur at 100dB (mower, motorcycle or chainsaw level) in just 15 minutes. Hearing damage occurs immediately at rock concerts and other loud events eventually reaching 115dB).
Common Dangerous Sounds
Hair dryers: 80-90dB
Sporting events: 100-115dB
Power tools: 85-100dB
Headphones at full volume: 100-110dB
Sirens: 120dB
Protection Strategies
Adhere to the 60/60 rule with headphones: Limit volume level to no more than 60% for only up to an hour at a time. Those cheap giveaways are no replacement for a quality set of ear protection so invest in them next time you go out where it’s loud. Regularly get away from it all.
Warning Signs
Signs of excessive noise include ringing ears, difficulty hearing a conversation over background noise or having to raise your voice in order for someone who is an arm’s length away be able to understand you.
Your hearing is irreplaceable. If you are unsure, wrap it up — your future self will be glad.
