Hearing aids, crucial for those experiencing hearing loss, work by amplifying sounds but cannot restore normal hearing or entirely eliminate background noise. With various styles available, including completely in the canal (CIC) and behind the ear models, each type brings its own set of advantages and considerations such as size, visibility, and battery life [1]. Features like noise reduction, wireless connectivity, and rechargeable batteries further enhance the user experience, making hearing aids an essential tool for better hearing [1]. However, choosing between one or two hearing aids often depends on whether a person has unilateral or bilateral hearing loss, highlighting the importance of consulting with a hearing specialist to make an informed decision.

Before selecting hearing aids, it’s advised to undergo a thorough hearing test by a specialist, who can then recommend the most suitable option based on the type and severity of the hearing loss, lifestyle needs, and manual dexterity. Technological advancements have also led to the availability of over-the-counter (OTC) hearing aids for those with mild to moderate hearing loss, offering a more accessible solution [2]. This guide aims to provide insights into making the best choice between one or two hearing aids, considering various aspects such as health insurance, financial assistance options, and the latest in hearing aid technology.

Understanding Hearing Loss

Hearing loss manifests in various forms and understanding its types and degrees is crucial for selecting the appropriate hearing aid. Here’s a breakdown of the types and classifications of hearing loss:

Types of Hearing Loss:

types of hearing loss
conductive hearing loss
sensorineural hearing loss
mixed hearing loss
  1. Conductive Hearing Loss: Occurs when sound is blocked in the outer or middle ear. Common causes include earwax buildup, fluid in the middle ear, infections, and ruptured eardrums.
  2. Sensorineural Hearing Loss: Results from damage to the inner ear or nerve pathways from the ear to the brain, often irreversible. Causes range from aging, noise exposure, hereditary factors, to diseases like Meniere’s and otosclerosis.
  3. Mixed Hearing Loss: A combination of conductive and sensorineural hearing loss, involving both the outer/middle and inner ear.

Degrees of Hearing Loss:

degree of hearing loss
mild
moderate
severe
profound
  • Mild: Soft sounds are hard to hear.
  • Moderate: Normal conversation is difficult to understand.
  • Severe: Only loud voices are barely audible.
  • Profound: Only very loud sounds are heard.

Classification Based on Timing and Laterality:

  • Pre-lingual vs. Post-lingual: Determines if the hearing loss occurred before or after speech development.
  • Unilateral vs. Bilateral: Hearing loss affecting either one ear or both ears.

For individuals with bilateral hearing loss, using two hearing aids is often recommended to ensure balanced hearing, which aids in better sound localization and understanding in noisy environments. However, for those with unilateral hearing loss, a single hearing aid may suffice, depending on their specific hearing needs and daily activities.

Understanding these nuances is essential when choosing between one or two hearing aids, as each type of hearing loss and its severity can significantly influence the effectiveness of the hearing aid. It’s advisable to consult with audiologists who can provide detailed evaluations and recommend the most suitable hearing aids, considering the unique aspects of each individual’s hearing loss. Moreover, FDA-approved over-the-counter (OTC) hearing aids offer a convenient option for adults with mild-to-moderate hearing loss, simplifying the process of acquiring hearing assistance without a prescription.

Benefits of Two Hearing Aids

There are numerous benefits to wearing two hearing aids compared to just one, especially for individuals with bilateral hearing loss. Here are some key advantages:

  1. Enhanced Sound Localization and Safety:
    • Sound Localization: Two hearing aids significantly improve the ability to determine the direction from which sounds are coming. This is crucial not only for everyday interactions but also for safety, as it helps in identifying potential dangers in the environment.
    • Safety Considerations: Better sound localization contributes to safer navigation in various settings, particularly in traffic or crowded places.
  2. Improved Speech Understanding and Listening Comfort:
    • Speech Clarity in Noise: Wearing two hearing aids helps in distinguishing speech from background noise, making conversations easier to follow in noisy environments. This is due to the binaural summation effect, where the brain combines auditory inputs from both ears to filter out unwanted noise.
    • Reduced Listening Effort: With both ears assisted, the strain of trying to hear with only one good ear is eliminated, reducing listening fatigue and making communication more enjoyable.
    • Music and Television: Enhanced auditory input from two hearing aids provides a richer and more balanced sound experience when listening to music or watching television.
  3. Preservation of Auditory Health and Function:
    • Auditory Deprivation: Using two hearing aids prevents the unaided ear from auditory deprivation, which can lead to deteriorated hearing ability over time.
    • Tinnitus Relief: For individuals experiencing tinnitus, using two hearing aids can provide more effective relief. The additional stimulation helps mask tinnitus sounds and makes them less noticeable.
    • Long-Distance Hearing: The ability to hear sounds from a distance is greatly improved, which is beneficial in various social and public scenarios.

These advantages underscore the importance of choosing dual hearing aids for those with hearing loss in both ears. It’s essential for individuals to consult with an audiologist to assess their specific needs and determine the best auditory support, ensuring a balanced and effective hearing solution.

When is One Hearing Aid Sufficient?

Deciding between one or two hearing aids often hinges on the specific hearing loss condition of an individual. Here are scenarios when one hearing aid might be sufficient:

  • Unilateral Hearing Loss: If a person experiences hearing loss in only one ear while maintaining normal or nearly normal hearing in the other, a single hearing aid is typically adequate. This setup helps balance the hearing capabilities without unnecessary intervention in the ear that hears well.
  • Financial and Personal Considerations:
    • Cost Concerns: The decision to opt for one hearing aid may be influenced by budget constraints. Hearing aids can be expensive, and not all costs are covered by health insurance. In such cases, if one ear has significantly better hearing than the other, it might be economically sensible to aid only the impaired ear.
    • Trial Periods: For those uncertain about the benefits of dual hearing aids, many audiologists offer a trial period. This allows users to assess the difference in hearing with both one and two devices. If there is no noticeable improvement with two, they may choose to continue with a single hearing aid.
  • Real-Life Application and Professional Advice:
    • Case Example: Mark Pollard, a patient from the Berkeley Hearing Center, encountered single-sided hearing loss due to head trauma during his teens. By using a non-invasive hearing aid on the affected side, he noted a significant enhancement in his quality of life, demonstrating that one well-fitted hearing aid can be sufficient depending on the individual’s condition and lifestyle needs.
    • Audiologist Consultation: It is crucial to consult with a hearing professional who can evaluate the degree of hearing loss and lifestyle needs. This personalized assessment helps in making an informed decision about whether to use one or two hearing aids.

Choosing the right number of hearing aids is not just about addressing the auditory deficiency but also enhancing overall communication, safety, and quality of life. Each case should be considered individually, with professional guidance, to determine the most effective auditory support strategy.
