How do we hear sound? Here is a quick overview of how our ears work:
Known as the pinna or auricle, this visible portion of the ear gathers sounds from the surrounding environment and sends it down the ear canal.
The vibration of the tympanic membrane (eardrum) transmits sound to the inner ear through three small bones (malleus, incus and stapes) that carry sound to the inner ear.
Made up of two main parts: the cochlea, a system of complex hair cells (sensory cells) and the vestibular system that sends sound to the brain for final processing.
Hearing impairments can occur in all parts of the ear; problems of the outer or middle ear can generally be treated with medication or surgery.
However, damage to the inner ear is responsible for about 80% of all hearing impairments. The good news is that modern hearing aids can compensate for most inner ear damage.
Several key configurations enable you to hear better while wearing them:
The circuit is manipulated by sophisticated software to do the following:
