Insights

The Frequency-specific Animal Sound Test (FAST4) is effective for preschool hearing screening in children over 4 years old, showing results comparable to pure tone audiometry (PTA). Further improvements are in the mFAST model.

Area of Science:

  • Pediatric Audiology
  • Hearing Screening Technologies

Background:

  • Monitoring children's hearing is crucial from birth through school age.
  • Universal newborn hearing screening (UNHS) is standard, but ongoing assessment is vital.
  • Assessing hearing in preschool and school-aged children requires appropriate tools.

Purpose of the Study:

  • To evaluate the Frequency-specific Animal Sound Test (FAST4) for children aged 2.5–10 years.
  • To compare FAST4 hearing thresholds with pure tone audiometry (PTA).
  • To determine the clinical utility of FAST4 in pediatric settings.

Main Methods:

  • 322 children (2.6–14.1 years) and 41 adults were tested with FAST4 using animal sounds via headphones.
  • Hearing thresholds were determined for high and low frequencies using FAST4.
  • Children's hearing thresholds were also measured using PTA.

Main Results:

  • Analysis included 156 normal-hearing and hearing-impaired children, primarily over 4 years old.
  • FAST4 demonstrated comparable hearing levels to PTA in both children and adults.
  • FAST4 testing was often prematurely stopped in children younger than 4 years.

Conclusions:

  • FAST4 is a promising tool for preschool hearing screening, offering advantages in simplicity and efficiency.
  • The test can be administered by non-specialist staff.
  • An improved successor model, mFAST, has been developed.
