Hearing Aids and Hearing Impairments

Hearing Aids and Their Use

Definition of Hearing Aids
- Hearing aids are devices placed in or near the ear to assist individuals with hearing. The purpose of these devices is to enhance sound perception and improve the ability to listen.
Types of Hearing Aids
- There are various types of hearing aids, which can be categorized into different styles such as:
- Behind-the-ear (BTE)
- In-the-ear (ITE)
- Completely-in-canal (CIC)
- Some patients may also have cochlear implants, which are surgically implanted devices that work directly with the auditory nerve to provide hearing assistance.
- Visual aids may be provided to illustrate different types of hearing aids.

Daily Reminders
- Caregivers should remind clients to wear their hearing aids each morning before their activities. This ensures optimal use throughout the day.
Proper Placement
- It is crucial to insert the hearing aid correctly. If placed backwards or incorrectly, it may not function properly.
- Ensure that any duct deposits in the hearing aids are cleared before insertion. This can be done with a clean paper or cloth while using gloves.
Water Exposure
- Hearing aids should be removed before bathing or showering to prevent damage from water exposure, as they often contain batteries which can be ruined by moisture.
Safe Storage
- Caution should be exercised with clients who may misplace their hearing aids, such as placing them under pillows or in laundry. Regular checks should be made to ensure hearing aids are not accidentally collected with linens or garbage.
Troubleshooting Hearing Aids
- If a hearing aid does not function as expected, troubleshooting steps include:
- Check the battery power and ensure it is charged or not expired.
- Ensure the device is turned on, as some aids have a small switch which can be easily overlooked.
- Confirm the hearing aid is correctly oriented, with appropriate labeling for right and left ear.
Recharging Hearing Aids
- For rechargeable hearing aids, ensure they are placed in the charger correctly and not washed, but cleaned gently with a tissue only.

Common Causes of Hearing Impairments
- Several diseases can contribute to hearing disorders:
- Otitis Media
  - This is a frequent ear infection found especially in children, often compounded by flu or colds. It can lead to blocked ear tubes, preventing proper drainage, potentially causing permanent damage if left untreated.
  - Antibiotics might be prescribed to combat ear infections in pediatric cases.
- Meniere's Disease
  - Characterized by fluid buildup in the inner ear, causing pressure and imbalance. Symptoms include:
  - Vertigo (dizziness)
  - Tinnitus (ringing in the ears)
  - Nausea and vomiting associated with dizziness
  - Symptoms are usually unilateral (affecting one ear) though they can worsen without treatment.
- Presbycusis
  - Age-related hearing loss predominantly affecting older adults. It results from gradual degradation of the auditory system, particularly within the nervous system. Once neurons degrade, there is no restorative treatment available.
Testing Body Language and Lip Reading
- Individuals with hearing impairments may resort to body language and lip reading to assist their understanding of conversations.
- Caregivers should ensure clear communication by positioning themselves appropriately and speaking clearly and at a moderate pace to enhance comprehension.

Maintaining Hearing Aids
- Regular checks should be made on hearing aids to ensure optimal performance. This includes:
- Verifying cleanliness and operational status before use each day.
- Ensuring safe storage practices are in place to prevent loss or damage.
Communication Techniques
- Use clear, slow, and deliberate speech, particularly keeping facial expressions visible to support any non-verbal communication needs. This enhances the resident's ability to comprehend interactions effectively.
