Gaps-in-Noise test: gap detection thresholds in 9-year-old normal-hearing children

Area of Science:

• Audiology
• Pediatric audiology
• Auditory processing

Background:

• The Gaps-in-Noise (GIN) test is crucial for assessing auditory processing abilities.
• Establishing normative data for pediatric populations is essential for accurate diagnosis.
• Previous research has not comprehensively defined GIN test norms for 9-year-old children.

Purpose of the Study:

• To establish standard criteria for the Gaps-in-Noise (GIN) test in 9-year-old normal-hearing children.
• To determine the mean gap detection thresholds in this age group.
• To investigate the influence of gender and ear on gap detection thresholds.

Main Methods:

• Forty normal-hearing children (20 male, 20 female, aged 9 years 0 months to 9 years 11 months) participated.
• Procedures included audiological evaluation, acoustic immittance measures, Dichotic Digits Test, and the GIN test.
• Statistical analysis was performed on the collected data.

Main Results:

• No significant differences were found between the performance of the right and left ears.
• Gender did not influence the gap detection thresholds.
• The mean gap detection thresholds were 4.4 ms for the right ear and 4.2 ms for the left ear.

Conclusions:

• The obtained mean gap detection thresholds and standard deviations can serve as normative criteria for 9-year-old children.
• These criteria are applicable regardless of the ear tested or the child's gender.
• This study provides valuable normative data for the GIN test in pediatric audiology.
