Home Report Understanding the degrees of hearing loss How sound is measured The loudness of sound is primarily measured in units called decibels dB. For example, here are decibel levels for some common sounds: Breathing: 10 dB Normal conversation: dB Lawnmower: 90 dB Rock concert: dB Gunshot: dB Prolonged exposure to sounds louder than 85 dB can cause damage to your hearing; sound at dB is uncomfortable and dB is the threshold of pain.
When measured together, decibels and hertz tell the degree of hearing loss you have in each ear. At each frequency, between 20 Hz and 20 kHz, the threshold of our sensitivity is different.
The best threshold at around 2 kHz is close to 0 dB. It is also in this middle range of frequencies that the sensation dynamics is the best dB. The conversation area dark green demonstrates the range of sounds most commonly used in human voice perception; when hearing loss affects this area, communication is altered. Connexion Powered by eZPublish - Ligams. The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear.
Generally speaking, the louder the sound, the higher the decibel number. So, just how loud is 50, 65, 75, or even 95 decibels? These benchmarks should give you an idea. Researchers have discovered that extended or repeated noise exposure to levels of 85 decibels or above can cause permanent hearing loss. When it comes to protecting yourself from damaging levels of sound, wear hearing protection or avoid environments with a sound volume higher than 85 decibels.
The louder the noise level, the less time it takes for the damage to take place. In fact, for every 10 decibels of noise exposure, the intensity of the sound goes up 10 times. At 85 decibels, the maximum recommended exposure time is 8 hours. By decibels, the noise exposure limit drops to 15 minutes, and at 10 decibels more dB , the risk exposure time plummets to just one minute.
Exposure to sound levels for longer than that could result in permanent hearing loss. Loud sounds are everywhere, and the damage can be permanent. The good news? This type of hearing loss is also very preventable.
There are several ways you can protect yourself from the harmful effects of high noise levels. Learn which sounds in your environment are too loud.
For sounds that you can control, dial down the volume to a safer decibel level. Skip directly to site content Skip directly to page options Skip directly to A-Z link. Section Navigation. Facebook Twitter LinkedIn Syndicate. What Noises Cause Hearing Loss?
