Assessing Speech Perception and Amplification Benefit During Infancy

May 30, 2025 updated by: University of Colorado, Denver

The goal of this project is to compare aided and unaided speech discrimination among infants with hearing loss and a cohort of infants with typical hearing.

Working Hypothesis: Among this group of infants with hearing loss, performance will be significantly better when infants are tested while using amplification (i.e., aided condition) compared to when tested without amplification (i.e., unaided condition). Infants fit with optimally programmed amplification will perform similarly to the infants with typical hearing on speech discrimination tasks.

Conditions

Conditions

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 years to 8 months (Child)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Infants between 6 and 36 months of age (inclusively) will be be enrolled in either the normal hearing or hearing loss cohort based on hearing status. Infants will be recruited from the community as well as through established clinical relationships with the principal investigator at Children's Hospital Colorado Audiology Centers.

Description

Inclusion Criteria:

  • Children between the ages of 6 months and 36 months (inclusive) at the time of enrollment.
  • English is the primary spoken language in the home
  • Demonstrated ability to complete a conditioned head turn via visual reinforcement audiometry (VRA)

  • If normal hearing

    -Normal hearing sensitivity bilaterally

  • If Hearing Loss

    • Children with diagnosis of bilateral sensorineural hearing ranging from mild to severe
    • Children currently using hearing aids
    • Children currently enrolled in intervention

Exclusion Criteria:

  • Children born earlier than 35 weeks gestation
  • Children with abnormal tympanometry on the day of testing
  • Children with concerns of secondary disabilities
  • Children with Auditory Neuropathy
  • Concerns of hearing loss in normal hearing children

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Normal Hearing
Group 1 will consist of approximately 20 infants with normal hearing. This cohort will have passed their newborn hearing screenings and will pass audiologic measurements on the day of testing. Audiologic measurements include tympanometry to determine middle ear function and otoacoustic emissions testing to determine cochlear integrity.
Hearing Loss
Group 2 will consist of approximately 20 infants with diagnosed bilateral sensorineural hearing loss ranging from mild to severe. These infants will also pass audiologic measures on the day of testing (tympanometry as described in group 1), currently use bilateral air-conduction hearing aids, and are enrolled in early intervention services.
Device: Hearing Aids
Hearing aids will be used by infants with a diagnosed sensorineural hearing loss.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Behavioral Speech Perception
Time Frame: Through study completion, up to 6 weeks pending subject factors (e.g., fatigue, otitis media)
To measure speech perception ability, infants are trained to complete a task in response to a change in a speech sound played over a speaker. Scores are given in d' (or equivalent) and are calculated from both true and false responses. Scores can range from 0.97 and 3.00. Scores above 1.2 are considered significantly above chance indicating successful perception of speech contrasts. To separate issues such as speech discrimination abilities versus proper conditioning, if a child is unable to discriminate a speech contrast (e.g., /ba-da/ or /sa-sha/) testing will transition to the 'easier' speech contrast /a-i/. If the child can discriminate between /a-i/, the investigators will repeat the previously tested contrast. Upon completion of this contrast the next contrast in will be assessed based on randomization ordering. If either contrast was not assessed/the child did not reach criterion, the participant will be rescheduled within 1 month, pending subject factors.
Through study completion, up to 6 weeks pending subject factors (e.g., fatigue, otitis media)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Aided Behavioral Speech Perception Improvement
Time Frame: Through study completion, up to 6 weeks pending subject factors (e.g., fatigue, otitis media)
Scores are measured from 0 to 2.03. Higher scores indicate greater benefit from hearing aid use in the hearing loss cohort.
Through study completion, up to 6 weeks pending subject factors (e.g., fatigue, otitis media)
