How Old Are Your Ears?

Comments: 0

Most hearing assessments measure pure tone thresholds between 250 Hz and 8000 Hz but this simple test goes to 19000 Hz. Don’t be discouraged if you can’t hear above 8000 Hz but consider booking a test if only one or two of these frequencies are audible to you.

The two most common causes of permanent hearing loss in adults are presbycusis (hearing loss due to aging) and noise induced hearing loss from long-term exposure to noise.

Prolonged exposure to noise over 85db will likely cause damage over time. But just how loud is 85db? Here are some common sources of noise, ranked by how dangerous they can be.
