Q

speech detection/speech awareness threshold (SDT/SAT)

A
  • used when patient cannot repeat words
  • can use with children, foreign speakers, developmental delay, brain injury. etc.
  • has limited diagnostic value
  • can be used to estimate SRT
  • usually is 10-15 dB lower than SRT
  • CANNOT be used to predict pure tone average
  • usually obtained using childs name
2
Q

what does SDT measure

A

the patients ability to DETECT the presence of speech

-do not need to identify word

3
Q

SRT and pure tone

A

should be similar

4
Q

speech recognition threshold (SRT)

A
  • obtained by having pt point to pictures of repeat spondaic words back
  • useful for gaining info about child’s hearing sensitivity in 500-2000 Hz
5
Q

speech discrim/ word recognition (WRT)

A
  • can help understand the impact of HL on speech understanding abilities
  • list of phonetically balanced words read to pt 45 dB ABOVE SRT and repeat back word
  • scored as a percentage
  • %es broken down in ranges (poor, good, etc)
  • poor score may reflect retro cochlea loss
  • score doesn’t always match audio
