Respiration audiometry with pre-school children

Area of Science:

• Pediatric Audiology
• Auditory Perception Research
• Child Psychology

Background:

• Assessing hearing in preschool children presents unique challenges.
• Traditional audiometry methods may be difficult for very young children to tolerate.
• Respiration audiometry offers a potential alternative for objective hearing assessment.

Purpose of the Study:

• To evaluate the feasibility of respiration audiometry in preschool-aged children.
• To determine the reliability and validity of respiration audiometry in this age group.
• To identify potential challenges in implementing respiration audiometry in clinical settings.

Main Methods:

• Respiration audiometry was conducted on 12 children aged 3.5 to 4.9 years.
• Test signals were presented at 1 kc/s, 1-second duration, at varying hearing levels (HL).
• Two ascending series (test and retest) were attempted, with responses monitored via a strain gauge on a dynograph.

Main Results:

• Only 5 out of 12 children completed both test series due to behavioral issues.
• A low ratio of positive respiratory responses was observed.
• A significant number of false-positive responses occurred, with 9/13 positive responses below the play audiometry hearing threshold level.
• A reliable hearing threshold level could not be estimated for any participant.

Conclusions:

• Respiration audiometry, in its current form, is not sufficiently reliable for preschool children.
• High rates of test incompletion and false-positive results limit its clinical utility.
• Further research and refinement are necessary before respiration audiometry can be recommended for pediatric audiology clinics.
