Hearing aids come in a wide variety of shapes, sizes and models. Our consumer's guide consists of consolidated information to assist you in understanding all aspects of hearing aid devices to better make you an informed user and shopper.
Whether you're a musician, hunter, industrial worker or swimmer, custom ear plugs protect your hearing and prevent discomfort while continuing the activities you enjoy.
There are 4 main types of hearing protection, they are: Formable Plugs, Premolded Plugs, Semi-aural Devices and Ear Muffs. For hearing protection devices to be effective, they must fit correctly and be worn correctly, i.e. formable plugs must expand to fully block the ear canal and must be in the ear and not just sitting on the outside.
To correctly insert earplugs, slowly roll and compress the plug into a thin cylinder or to the shape of a golf tee without inducing creasing. While the plugs are compressed, insert it well into the ear canal and hold it there while it begins to expand. A rough test of whether an earplug is inserted correctly can be applied by cupping your hands over your ears while listening to a steady noise. If the plugs are fitted correctly, the noise levels should be almost the same whether or not you are covering your ears. At What Noise Level Should I Use Hearing Protection? As a guide, a motor mower is about 80dBA and this is about the threshold above which a person with no auditory problems must protect themselves, particularly as the duration of the exposure lengthens. The higher the level of sound, the shorter the time that you can be exposed before damage occurs.
The diagram below illustrates the noise levels and corresponding lengths of exposure at which damage to the auditory system can occur.
