The word Noise come from a latin word noxia meaning "injury" or "hurt" . Noise is an unwanted unpleasant annoying sound caused by vibration of the matter.
Vibrations impinge in to the ear drum of human or animal to setup a nervous disturbance, which we call sound. When the effect of sound a undesirable that it maybe termed as "Noise".
Why do you need Noise Protection?
When we are exposed to harmful noise - sounds that are too loud or loud sounds that last a long time - sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss. These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back. Noise-induced hearing loss is irreversible, and there is no cure.
What is Noise-induced hearing loss?
Noise-induced hearing loss can be caused by a one-time exposure to an intense impulse sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a mine or factory, or those who shoot regularly.
How do you measure your noise exposure?
Sound is measured in units called decibels. On the decibel scale, an increase of 10 means that a sound is 10 times more intense, or powerful. To your ears, it sounds twice as loud. The humming of a refrigerator is 45 decibels, normal conversation is approximately 60 decibels, and the noise from heavy city traffic can reach 85 decibels. A noisy factory can reach levels of up to xx decibels.
What are the sources of noise that cause hearing loss?
Sources of noise that can cause noise-induced hearing loss include wind noise on motorcycles, firearms, mines, factories and construction sites, which can emit sounds from 85 decibels up to 150 decibels. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sounds, the shorter the time period before noise-induced hearing loss can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss.
What can happen if you don’t wear Noise Protection?
Hearing loss can be a direct result of an occupation, a recreational activity or simply exposure to loud sounds. From specialty custom earplugs to musicians' sound attenuators, we offers a variety of protection and listening enhancement products.
How can you prevent hearing loss?
Custom fit earplugs provide outstanding noise protection for a variety of recreational and occupational environments.
We provide hearing protectors fit snugly and comfortably into your ear-canal, allowing you to use telephones, walkie-talkies and earmuffs without having to remove them.
