what is an audiogram?

 
AUDIOGRAM
  • An audiologist tests a person's hearing and produces an audiogram based on the results.
  • The audiogram is a graphical representation of a person's hearing in response to tones.
  • It records the softest level that a person is able to hear sounds in the right and left ear, from low pitches to high pitches.
THE AUDIOGRAM & SPEECH SOUNDS
  • Most consonants fall in the higher pitches
  • Vowels fall in the lower pitches
  • People with a hearing loss often lose their high pitched hearing first, making it difficult for them to hear consonants.
  • With only the vowels, it will sound as if someone is mumbling.

PUTTING IT ALL TOGETHER

  • Consonants are more important than vowels for speech understanding.
  • Consonants are spoken more softly than vowels and become masked in noisy environments.
  • Consonants are higher-pitched and most hearing losses occur in the higher pitches
  • People with a hearing loss often complain of people mumbling, or say they can hear the words but not understand them. This is due to a loss of consonants in speech.
