Sound affects our hearing.

While we are surrounded by sounds everyday, we don’t often consider that some of these sounds could be loud enough to cause noise-induced hearing loss (NIHL). According to the Hearing Health Foundation, when we are exposed to harmful noise that is either too loud and/or that lasts a long time – sensitive structures in our inner ear can be damaged, causing NIHL.

What sounds cause NIHL?
NIHL 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 at a rock concert or loud sports event.

The loudness of sound is measured in units called decibels. For example, the humming of a refrigerator is 40 decibels, normal conversation is approximately 60 decibels, and city traffic noise can be 85 decibels.

Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. It is always important to be aware of the distance from the source of the sound as well as the duration of exposure to the sound. It is recommended to avoid noises that are too loud and/or

Ear protection for hunting and high decibel noise. Protect your ears while shooting at the range or hunting.

A simple gunshot registers at 140 decibels which is significant enough to cause permanent hearing loss.  Signia custom ear protection for hunting and high-decibel noise is specifically designed for these transient types of sounds. They are custom-made to fit your ear so they offer maximum protection from loud, harmful sounds and the sudden “impulse noise” coming from a gun.

There are many other sounds that can cause damage to your ears. For example, an active snowmobile registers at 110 decibels, a jet ski at 115 decibels, even heavy traffic registers at 85 decibels. Prolonged exposure to these types of noises can cause gradual and sometimes permanent hearing loss. Ear protection is also beneficial in these situations.
