Permanent Threshold Shift (PTS)

What is a Permanent Threshold Shift?

PTS is a permanent reduction in the sensitivity of the ear to sound. It is caused by damage to the hair cells in the inner ear, which are responsible for converting sound waves into electrical signals that are sent to the brain.

What is an example of a permanent threshold shift?

An example of a PTS would be a person who has lost their hearing due to exposure to loud noise.

What causes a permanent threshold shift?

The most common cause of PTS is exposure to loud noise. Other causes include certain medications, infections, and head injuries.

What are temporary threshold shift TTS and permanent threshold shift pts?

Temporary Threshold Shift (TTS) vs. Permanent Threshold Shift (PTS): TTS is a temporary reduction in the sensitivity of the ear to sound. It is caused by exposure to loud noise, but the hearing usually returns to normal within a few hours or days. PTS is a permanent reduction in the sensitivity of the ear to sound. It does not return to normal, even after the exposure to loud noise has stopped.

Is a standard threshold shift permanent?

Symptoms of PTS

The symptoms of PTS can vary from person to person, but they may include:

  • Difficulty hearing high-pitched sounds
  • Difficulty understanding speech in noisy environments
  • Feeling like people are mumbling
  • Having to turn up the volume on the TV or radio
  • Having difficulty hearing people who are talking from behind or to the side

Treatment for PTS

There is no cure for PTS, but there are treatments that can help to improve hearing. These treatments include:

  • Hearing aids: Hearing aids amplify sound, making it easier for people with PTS to hear.
  • Cochlear implants: Cochlear implants are electronic devices that can be surgically implanted in the inner ear. They can provide a sense of sound to people who are profoundly deaf.
  • Speech therapy: Speech therapy can help people with PTS to develop their speech and language skills.
