Cassie Blackburn
Period 4 Patient One Constant ringing, buzzing, or roaring in the ears or head (tinnitus)
Sounds may be distorted or muffled
May have difficult understanding speech
Can affect anyone
Someone with NIHL may not even be aware that they have it, but it can be detected with a hearing test Symptoms There are no actual treatments because once you lose your hearing, it's permantent and there is no way of truly correcting it Treatments know which noises can cause damage (those at or above 80 dB)
wear earplugs or other hearing protective devices when involved in loud activity
be alert to hazardous noises
protect the ears of younger children
if you suspect that you have hearing loss, have a hearing test performed by an audiologist Preventition Hearing loss is permanent and there is no true way of correcting it. Tinnitus may improve or get worse over time but most people learn to tolerate it by ignoring the constant ringing or using different strategies to block out sound. Prognosis Noise Induced Hearling Loss What is NIHL? Long-term exposure to high intensity sounds such as noise generated from machinery in factories that damage sensitive structures within the inner ear. It affects the sensory hair cells in the cochlea. Patient One A 45-year-old machine operator at a local factory. Lately, he has been complaining of a constant ringing in his ears and has noticed that he has a difficult time following conversation. His wife convinced him to get his hearing tested, and an audiologist found that he has noise-induced hearing loss with moderate to severe sensorineural hearing loss in both ears at frequencies around 4000 Hz and mild sensorineural hearing loss in both ears at frequencies around 8000 Hz. The hearing loss is accompanied by tinnitus.
