Aided Audiogram

Aided Audiogram

An aided audiogram is a hearing test that measures a person’s hearing ability while wearing hearing aids or other assistive listening devices. This test is crucial for assessing how well the hearing aids are functioning and whether they are providing the necessary amplification to help the individual hear better.

Purpose of an Aided Audiogram

1. Evaluate Hearing Aid Performance:

   • Determines how much improvement the hearing aids provide compared to unaided hearing.
   • Helps ensure that the hearing aids are appropriately programmed and fit the user's needs.

2. Fine-Tune Hearing Aids:

   • Identifies if adjustments are needed in the hearing aid settings to better match the individual's hearing loss profile.
   • Assists audiologists in customizing the hearing aids to improve speech understanding and overall sound quality.

3. Monitor Hearing Changes:

   • Tracks changes in hearing ability over time, ensuring that hearing aids continue to provide optimal support as hearing changes.

How an Aided Audiogram Works

1. Preparation:

   • The individual wears their hearing aids, which have been previously fitted and programmed by an audiologist.
   • The test is usually conducted in a soundproof booth to eliminate external noise.

2. Testing Procedure:

   • The audiologist presents a series of tones (pure tones) at different frequencies and volumes through speakers or headphones.
   • The person is asked to respond whenever they hear a sound, usually by pressing a button or raising a hand.
   • The test is conducted for both ears, with the hearing aids on, to measure the aided hearing thresholds.

3. Speech Testing:

   • In addition to pure tone testing, speech audiometry may be conducted to assess the person's ability to understand speech while using their hearing aids.
   • This involves repeating words or sentences presented at different volume levels and in various listening environments (quiet and noisy).

Results Interpretation

• Audiogram Chart:

  • The results are plotted on an audiogram, with the hearing thresholds recorded for each ear at different frequencies.
  • The aided audiogram is compared to the unaided audiogram (audiogram without hearing aids) to assess the improvement provided by the hearing aids.
  • Ideally, the aided audiogram should show better hearing thresholds, closer to the normal hearing range.

• Speech Understanding:

  • The test results help determine how well the person understands speech with their hearing aids, which is crucial for everyday communication.

Importance of Aided Audiograms

1. Ensuring Effective Amplification:

   • Confirms that the hearing aids are providing the right amount of amplification to meet the user's needs, ensuring better hearing in various environments.

2. Personalized Hearing Aid Adjustment:

   • Provides valuable feedback to the audiologist for fine-tuning the hearing aids, making sure they are customized for the individual's hearing loss and preferences.

3. Continuous Monitoring:

   • Helps in tracking the effectiveness of hearing aids over time, especially if the person’s hearing deteriorates or if there are changes in their listening environments.

4. Enhanced Quality of Life:

   • Ensures that the hearing aids are enabling the individual to hear and understand speech more effectively, improving their quality of life.

When is an Aided Audiogram Needed?

• After Fitting New Hearing Aids:

  • To verify that the new hearing aids are providing the intended benefit.

• Routine Hearing Aid Check-ups:

  • As part of regular maintenance and monitoring to ensure the hearing aids are functioning well over time.

• When Hearing Issues Persist:

  • If the person continues to have difficulty hearing even with hearing aids, an aided audiogram can help identify any issues with the device's settings or performance.

Benefits of an Aided Audiogram

• Objective Assessment:
  • Provides measurable data on how well hearing aids are working.
• Improved Hearing Experience:
  • Ensures that hearing aids are effectively supporting the user, leading to better speech comprehension and overall hearing satisfaction.
• Guides Further Adjustments:
  • If the aided audiogram indicates suboptimal performance, it guides the audiologist in making precise adjustments to improve hearing outcomes.

An aided audiogram is a vital part of the hearing aid fitting and maintenance process, ensuring that hearing aids are tailored to the individual’s needs and are providing the best possible hearing support.
