Unusual sounds from a hearing aid
can be caused by several reasons.

  1. Check the battery to ensure your hearing aid still has sufficient power. Low battery levels may cause abnormal sound.
  2. Clean the hearing aid, as earwax or dirt buildup may cause sound interruptions or unusual noises. Use the brush provided with the device to carefully clean all parts.
  3. Check the cables and accessories. If your hearing aid has wires or external parts, make sure all connections are secure. The cable may be damaged or not connected properly.
    Adjust the sound settings. Sometimes the settings may have been changed accidentally. Try checking and adjusting the volume or programs again.
  4. Inspect the earmold or ear tips. The earmold/ear tip may be damaged or may not fit properly, causing echo or strange sounds. Try adjusting or replacing them.
  5. Reset the hearing aid by turning it off and on, or follow the reset instructions in the user manual.
  6. Consult a specialist if none of the above steps solve the issue. Bring your hearing aid to a professional or service center for further inspection.

This basic inspection may help fix the issue or identify the cause of the unusual sound. If you need further guidance, please provide more details about the problem so I can offer more accurate advice.

What is Audiogram?

An audiogram is a chart that displays the results of a hearing test, showing a person’s ability to hear sounds at different frequencies and loudness levels.

Components of an Audiogram:

Horizontal axis (X-axis): Represents sound frequency (in Hz – Hertz), starting from low frequencies on the left to high frequencies on the right

  • Low frequencies: 125, 250, 500 Hz

  • Mid frequencies: 1000, 2000 Hz

  • High frequencies: 4000, 8000 Hz

Vertical axis (Y-axis): Represents sound intensity (in dB – decibels), with louder sounds shown further down the chart

  • Soft sounds: -10 to 30 dB

  • Moderate sounds: 40 to 70 dB

  • Loud sounds: 80 dB and above

How to Read an Audiogram:

  • Each point on the graph shows the softest level of sound a person can hear at a specific frequency.

  • Symbols are used to represent the results for each ear:

    • Right ear: usually marked with “O” and often in red

    • Left ear: usually marked with “X” and often in blue

Examples of Audiogram Interpretation:

  • If all points fall between 0–20 dB at all frequencies, hearing is considered normal.

  • If points fall around 40–60 dB at all frequencies, this indicates moderate hearing loss.

  • If points drop below 80 dB at high frequencies, it suggests severe high-frequency hearing loss.

Using the Audiogram for Hearing Aid Adjustment:

  • Audiogram data is essential for programming a hearing aid according to the user’s hearing profile.

  • The hearing aid is adjusted to amplify sounds at the frequencies where hearing loss is present.

Understanding an audiogram helps you fine-tune hearing aids more effectively and ensures the best possible sound quality for everyday listening.

Understanding the decibel (dB) levels of various everyday sounds

It can help us understand the loudness of the sounds we hear and their impact on our hearing. Here are examples of common everyday sounds and their approximate decibel levels.

  1. Light breathing: 10 dB
  2. Falling leaves: 20–30 dB
  3. Whispering, refrigerator running: 30–40 dB
  4. Rainfall, normal conversation: 50–60 dB
  5. Cars, trucks, vacuum cleaner, whistle: 70–80 dB
  6. Hair dryer, lawn mower, factory noise: 90–100 dB
  7. Machinery, sirens, firecrackers, fireworks, nightclub music, rock concerts: 110–120 dB
  8. Jet taking off (close range), gunshot or firecrackers: 130–140 dB
  9. Rocket launch: 150–160 dB

Effects of Sound on Hearing

  • Sound at 70 dB or below: Safe for long-term listening and does not cause hearing damage.
    Sound at 85 dB or above: Prolonged exposure may lead to hearing loss. It is recommended to limit listening time at this volume.
    Sound at 120 dB or above: Can cause immediate hearing damage even with short exposure. Avoid or use hearing protection.

Hearing Loss Prevention

  • Use hearing protection: In loud environments such as construction sites, concerts, or airports.
    Lower the volume: When using headphones or listening to sounds from various devices.
    Take listening breaks: Pause exposure to loud sounds periodically to prevent ear damage.

    Knowing and understanding decibel levels of everyday sounds helps you take better care of your hearing and prevent long-term hearing loss.

Audiograms are extremely important for understanding and managing an individual’s hearing in daily life, especially for those with hearing difficulties. Here are the main reasons why audiograms are important:

  1. Diagnosis and Assessment of Hearing Loss
    Audiograms help doctors or hearing specialists accurately identify the level and type of hearing loss, which can be classified as mild, moderate, severe, or profound.

    Hearing Aid Adjustment
    Audiogram results are used to customize hearing aids to match an individual’s hearing profile. The hearing aid is programmed to amplify sounds at the frequencies and levels where the user has hearing difficulties.

    Selecting the Appropriate Hearing Device
    Audiograms assist in choosing the right type of hearing device, whether it’s a specific hearing aid or supplementary listening devices needed to improve hearing.

    Treatment and Therapy Planning
    Specialists can use audiogram data to plan treatments or therapies to improve hearing, or to apply techniques that assist with listening and communication in daily life.

    Evaluating Treatment or Hearing Aid Effectiveness
    Audiograms are used to monitor and assess the effectiveness of therapy or hearing aid use, helping to determine if hearing has improved and to adjust the treatment plan as needed.

    Understanding One’s Hearing Condition
    Individuals with hearing difficulties can use audiograms to better understand their hearing condition and recognize the importance of preventing further hearing loss.

    Daily Life Guidance
    Information from audiograms allows specialists to provide practical advice for daily life, such as choosing suitable places for conversation, using assistive listening technology in different situations, or avoiding excessively loud environments.

    Audiograms are a vital tool for managing hearing issues in daily life, providing valuable information for diagnosis, hearing aid customization, treatment planning, and effective guidance for everyday living.

Hearing aid sound analysis is an important process to ensure the device functions effectively and meets the specific needs of the user. Here are the steps and methods for analyzing sound from a hearing aid:
