	Noise, Ears and Hearing Protection, Hearing Loss Prevention
		Hearing impaired people often have difficulty detecting differences between certain words that sound alike, especially words that contain S, F, SH, CH, H, or soft C, sounds, because the sound of these consonant is in a much higher frequency range than vowels and other consonants.
		Studies have shown that one-half of the workers wearing hearing protectors receive one-half or less of the noise reduction potential of their protectors because these devices are not worn continuously while in noise or because they do not fit properly.
		Hearing protectors do slightly reduce the ability of those with damaged hearing or poor comprehension of language to understand normal conversation, However, it is essential that persons with impaired hearing wear earplugs or muffs to prevent further inner ear damage.

		Hearing aids are not indicated for an ear with minor hearing loss, and are also not very useful in an ear with profound hearing loss.
		An audiometric evaluation should be performed to determine the type of hearing loss (sensorineural, conductive or central), the degree, and the frequency slope. The evaluation should also be able to predict the amount of benefit of an aid, in terms of speech comprehension.
		As historically 2 out of every 3 hearing aids are not worn (at least often), and hearing aids are generally not covered by insurance and typically costs in the thousands of dollars, we recommend that you think about this carefully.
