- Low prices and a great value on hearing aids with the latest technology from Sonic Innovations, Oticon, Widex, Starkey, ReSound, and Phonak.
Welcome to Hearbright
Welcome to HearBright! Your hearing is our concern. For over a decade, our Doctors of Audiology specialists have served the medical community by providing hearing tests for pediatrics to seniors.
We also specialize in a wide range of hearing aids. Widex, Unitron, Phonak, ReSound, Starkey, Oticon, Audina, and Siemens are just some of the brand names we have available at low prices. We have low prices for name-brand hearing aids because our goal is to serve our community with top quality hearing aids at affordable prices. Come to our one of our diagnostic centers for a thorough hearing evaluation, and then come to our Hearing Aid Center for your hearing aids.
HearBright also specializes in the prevention of hearing loss. Earpieces for use with an iPod and earplugs for noise protection are just some of the ways we help.
Join the thousands of patients who come to us to care for their hearing!
HOW WE HEAR
THE HEARING SYSTEM
The anatomy of the hearing system can be divided into four components for our convenience in remembering the parts and associating these parts with their function. These divisions are the:
- 1. outer ear
- 2. middle ear
- 3. inner ear
- 4. central auditory pathways
The Outer Ear (1)
The outer ear is made up of the pinna or auricle and the external auditory canal. The pinna collects and funnels sound down the ear canal. The ear canal is curved, “S” shaped, and about 1 inch long in adults. It has hairs and glands that produce wax called cerumen. Cerumen helps to lubricate the skin and keep it moist.
The Middle Ear (2)
The eardrum (tympanic membrane) is a membrane at the inner end of the ear canal. On that inner side of the tympanic membrane is an air-filled space called the middle ear cavity. The vibrations of the tympanic membrane are transmitted through the malleus (hammer) incus (anvil) and stapes (stirrup), also called the ossicles. The stapes footplate transmits the vibrations into the inner ear.
The Inner Ear (3)
The inner ear has two divisions: one for hearing, the other for balance. The hearing division consists of the cochlea and the nerve of hearing. The cochlea is snail-shaped, bony structure that contains the sensory organ for hearing called the organ of Corti. The organ of Corti releases chemical messengers when the vibrations from the stapes activate its tiny hair cells. These then excite the nerves of hearing which carry sound to the brain.
Central Auditory Pathways (4)
The central auditory system is a complex network of neural pathways in the brain that is responsible for sound localization, speech understanding in noisy listening situations and other complex sounds, including music perception.
THE PROCESS OF "HEARING"
Sound is transformed into mechanical energy by the tympanic membrane. It is then transmitted through the ossicles to the inner ear where it is changed again into hydraulic energy for transmission through the fluid-filled cochlea. The cochlea’s hair cells are stimulated by the fluid waves and a neurochemical event takes place that excites the nerves of hearing. The physical characteristics of the original sound are preserved at every energy change along the way until this code becomes one the brain can recognize and process.
Hearing loss misleads our brain with a loss of audibility and introduces distortion into the message that reaches the brain. Changes in the effectiveness of the brain to process stimuli, from head trauma, disease, or from aging, can result in symptoms that mimic hearing loss. The ears and the brain combine in a remarkable way to process neural events into the sense of hearing. Perhaps it’s fair to say that we “hear” with our brain, not with our ears!
