Keep in mind there are a variety of mobile applications and hand-held noise meters available that monitor noise levels. Sounds 10 times louder than total silence would be. Sound is measured in decibels (Db) on a logarithmic scale. More powerful centerfire ammo is even louder. That’s loud enough to cause permanent hearing damage and physical pain. 22 caliber rifle with standard velocity ammo creates 140 dB of sound. It’s important to wear ear plugs or other hearing protection devices when engaging in noisy activities in order to prevent noise-induced hearing loss. As an example of how loud a gunshot can be, a. Without hearing protection, high-decibel exposure can damage hearing, especially when experienced at close range or for prolonged periods of time. The more you are around loud noises, the more you risk having hearing loss. It can also occur after you are exposed to loud noise in a short period of time, such as a gunshot or explosion. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off Noise-induced hearing loss is permanent hearing loss that is caused by being around loud noises over a long period of time.125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine.120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail.100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle.85 – 100 decibels: For example, a hair dryer, blender, power lawn mower, forklift, or subway train.
Levels and sources of damaging noise include: Keep in mind that exposure to sounds higher than 110 decibels can cause instantaneous hearing loss. With extended or up-close exposure, noises that reach 85 decibels or higher can cause permanent damage to the cilia, or hair cells, in the inner ear, leading to permanent hearing loss.
