How Does the Ear Work?
The human ear is a complex organ responsible for hearing and balance. It consists of three main parts:
- Outer Ear: Collects and directs sound through the ear canal.
- Middle Ear: Amplifies and directs sound to the inner ear.
- Inner Ear - Cochlea: Receives sound and converts it into electrical signals.
- Hearing and Balance Nerve: Carries the signals to the brain.
The Eustachian Tube, a thin tube connecting the middle ear to the back of the nose, helps with air flow in the middle ear.
What is Sensorineural Hearing Loss?
Sensorineural Hearing Loss (SNHL) is typically a permanent hearing impairment resulting from problems in the inner ear or the hearing and balance nerve connecting the ear to the brain. This condition can be caused by various factors, including:
- Aging
- Excessive noise exposure
- Viruses or infections
- Certain medications
- Genetic factors or birth conditions
- Ear or head injuries
How Will My Hearing Loss Affect Me?
The impact of hearing loss varies depending on its severity. Here are the levels of hearing loss and their effects:
- Mild Hearing Loss: Faint or distant speech may be difficult to hear.
- Moderate Hearing Loss: Close conversations are manageable, but more distant speech is challenging.
- Moderately-Severe Hearing Loss: Loud speech is necessary to hear in quiet environments; difficulty persists in noisy settings.
- Severe Hearing Loss: Speech is audible only when the speaker is close.
- Profound Hearing Loss: Only some loud sounds are audible.
Additional experiences may include:
- Ringing or buzzing sounds in the ear, known as Tinnitus
- Increased frustration or loneliness
- Listening fatigue
How Can I Manage My Hearing Loss?
While sensorineural hearing loss is usually irreversible, regular check-ups with an audiologist every 1 to 2 years are crucial. Audiologists may recommend the following management strategies:
- Hearing Aids: These devices boost sounds that are difficult to hear, aiding conversations in most situations. Trials may be available.
- Assistive Listening Devices (ALDs): These devices help in specific situations, with or without hearing aids. Examples include amplifying a doorbell or streaming audio from a phone or television to a hearing aid.
- Communication Strategies: An audiologist can teach techniques to improve conversation flow and manage hearing challenges.
