The booming U.S. economy, in which imports tripled from $23 million in 1790 to $78 million in 1807, brought in far more tariffs to pay off the debt. Still, the deficit-cutting plan hit a setback when Jefferson decided in 1803 to add $15 million of debt to the mound he inherited.
Prolonged exposure to loud sounds is the most common cause of tinnitus. Up to 90% of people with tinnitus have some level of noise-induced hearing loss. The noise causes permanent damage to the sound-sensitive cells of the cochlea, a spiral-shaped organ in the inner ear.
Inner Ear Hair Damage One of the main reasons for tinnitus is when you damage or injure hairs in your inner ear. When your inner ear senses any sound, very small and delicate hairs move to the sound wave pressure. This makes the ear cells emit an electrical impulse through the nerves in your ear and then on to your brain. The brain translates these impulses as sound.
