What Does my Audiogram Mean?

What Does my Audiogram Mean? In Canada, 19% of our 35 million population have hearing loss (Statistics Canada, 2013), and many more than that have their hearing tested regularly. So what does the audiogram mean? What information does it give me about my hearing? Well, here's a short explanation for you and what your audiogram means. What is an Audiogram? An audiogram is a graph used in audiology to plot your hearing levels. On this graph, you'll see the vertical line we call decibels (dB) and the horizontal line for frequency (hertz - Hz). Decibels are the units of volume or loudness used in audiology. Quiet sounds are at the top of the graph and as you go down the louder the sound is. Frequency is the pitch of the sound with low pitch on the left and high pitch on the right. We examine several frequencies from 250 to 8,000 hertz; this captures all the sounds in human speech and more. During a hearing test, we use this graph to chart how you respond to beeps at each frequency as we raise and lower the volume. Each ear is given a symbol, O for your right ear and X for your left. We'll look at these more in the next section. Information is on the Audiogram? After the hearing test is done, there are several important things to look at. First, we look at the responses of your right and left ear. Depending on where they fall on the graph...

Meniere's Ear

What is Meniere’s Disease

Meniere's Disease Meniere's disease, maybe you've heard of it, maybe you have it, but what is it? A disease of the inner ear, Meniere's specifically affects the snail-looking structure called the cochlea (the blue structure in the figure below). The cochlea plays a large role in our balance and transmitting sound into electrical signals the brain can understand. Meniere's affects roughly 600 people out of every 100,000; 80% of which only have it in 1 ear. Although, it can eventually move to the other ear. Yet even with so many people having it, there is still much unknown about this disease. Causes As mentioned above, we still don't know much about Meniere's, especially what causes it. Professionals suggest there are 4 possible causes: A build-up of endolymphatic fluid (fluid of the inner ear that creates the electrical signals) An autoimmune disease A viral infection Genetics Or a combination of the above Although we aren't certain, there are theories that support each of these possible causes. Symptoms Because of the organ it affects, the cochlea, Meniere's has 3 very distinct symptoms that appear in unpredictable episodes. Episodic hearing loss - usually with a low-frequency loss Vertigo Roaring Tinnitus Sometimes also accompanied by a feeling of fullness in the ear These symptoms can occur together or separately. Episodes of Meniere's can last for a few hours, days, or months and seem to happen at random. Although, some individuals with Meniere's can feel an episode coming on. Treatment The treatment protocol for each patient...
