Summary of the Video "L'audiogramma: cos'è e come si legge"

The video, presented by Giulia, an audiometrist and Audiologist at the Bo Technology Center for listening, explains what an Audiogram is and how to interpret it. The main ideas and concepts conveyed in the video include:

• Definition of Audiogram: An Audiogram is described as a "photograph" of an individual's hearing ability, visually representing the results of Hearing Tests.
• Color Coding:
  • Red lines on the Audiogram indicate results for the right ear.
  • Blue lines represent results for the left ear.
  • These colors are consistent with those used in Hearing Aids.
• Testing Frequencies:
  • The Audiogram is created by testing various frequencies:
    • Starting with 1000 Hz.
    • Higher frequencies are tested next (2000 Hz to 8000 Hz).
    • Low frequencies are tested last (125 Hz to 750 Hz).
• Testing Methodology:
  • The testing begins at a high volume and gradually decreases the intensity by 5 dB until the patient can hear the sound.
  • The patient's response (raising their hand) indicates their minimum audibility threshold for each frequency.
  • Each frequency is tested multiple times to ensure accuracy.
• Importance of the Audiogram: The Audiogram is crucial for adjusting Hearing Aids, as it provides the hearing aid technician with the necessary data.
• Age-related Hearing Loss:
  • High frequencies are typically the first to be affected by Age-related Hearing Loss, starting around the age of 30.
  • The video notes that individuals around 20-25 years old generally have normal hearing across all frequencies.
  • As one ages, hearing loss progresses from high frequencies to medium and finally to low frequencies.

Key Points:

• Audiogram: Visual representation of hearing ability.
• Color Codes: Red for right ear, blue for left ear.
• Frequency Testing Order: 1000 Hz → Higher frequencies → Lower frequencies.
• Testing Method: Start high volume, decrease until sound is heard (5 dB steps).
• Response: Patient raises hand to indicate hearing threshold.
• Hearing Loss Progression: High frequencies lost first, then medium, then low.
