Speech Audiometry

Speech Audiometry

Speech Audiometry is a test used to measure how well you can hear and understand spoken words. It evaluates two main aspects of hearing: Speech Reception Threshold (SRT) and Speech Discrimination (SD). Both are critical in understanding your ability to process and comprehend speech at different sound levels.

Types of Speech Audiometry Tests:

• SRT (Speech Reception Threshold):

  • This test determines the softest level at which you can hear and understand speech.
  • A set of familiar words is spoken at decreasing volume levels, and you are asked to repeat them. The audiologist lowers the volume until you can no longer accurately repeat the words. The point where your accuracy drops below 50% marks your speech reception threshold.

• Speech Discrimination (SD):

  • This test assesses your ability to distinguish and repeat words at a comfortable listening level.
  • Words are presented at a volume that you can hear well, and you are asked to repeat them. The speech is delivered at the same volume throughout, and the words are not repeated or revealed beforehand, making it more challenging.

How the Test Is Conducted:

• Both tests are done using headphones, with speech sounds delivered through the audiometer.
• For SRT, the audiologist will test your ability to hear and identify words at decreasing volumes.
• For SD, the audiologist presents words at a consistent volume and measures your accuracy in recognizing and repeating them.

After the Test:

• Once the speech audiometry is complete, the audiologist will review the results with you.
• Based on your performance, they may suggest:
  • Preventive measures, like using ear protection around loud noises.
  • Corrective actions, such as hearing aids or other hearing devices, if necessary.

Speech audiometry helps to determine how well you can comprehend speech in quiet and noisy environments, providing valuable insights for treatment or rehabilitation if needed.
