Early Hearing Detection and Intervention (EHDI) Funded Research Projects

Current Research Projects

Innovations for Electrophysiologic Assessment of Infant Hearing
University of Arizona

Project Summary:
The long-term goal of this research is to apply knowledge of auditory system development to the clinical challenge of assessing hearing abilities in infants and young children. The translational and immediate goal of this research proposal is to develop and implement cost-effective, sensitive and specific tools for infant auditory assessment that can be used by pediatric audiologists.

The specific aims of this project are: 1) To develop and implement new stimulus, signal processing and response evaluation methods for obtaining frequency-specific estimates of hearing thresholds that can be used in non-sedated infants. 2) To compare the sensitivity, specificity and the time required to complete a test using the innovative methods developed for specific aim 1, to existing technologies including a) a new technology using adaptive "Kalman" filters and in-situ bioamplifiers that are purported to allow signal extraction in high levels of electromyographic and/or electroencephalic noise. This will be a test of the Vivosonic Integrity ABR system. b) Conventional tone burst stimuli and signal processing algorithms (linear filtering, amplitude-based artifact reject, signal averaging), such as those employed by the majority of instruments designed for infant ABR assessment.

Developmental Outcome Feasibility Study: Deaf or Hard of Hearing
University of Colorado

The goal for this project is to assess the feasibility of providing technical assistance to a minimum of five states to develop data management systems that are capable of collecting and reporting developmental outcomes of infants and children identified through a hearing screening program.

Language and Behavioral Outcomes of Children with Congenital Hearing Loss: Family Perspectives Study II
Women and Infants Hospital, Providence, Rhode Island

The goals for this project are:

  • Conducting prospective comparisons of language, communication, behavior, and adaptive skills among (1) children identified early with minimal and mild hearing loss; (2) children identified early with moderate to profound bilateral hearing loss; and (3) typically hearing children at 36 and 48 months of age, and
  • Identifying the child, family, and intervention characteristics that contribute to the best possible outcomes.

Children’s Hospital of Philadelphia

The goals for this project included:

  • Learning more about current practices of clinical audiology programs across the United States that serve children with mild bilateral and unilateral hearing losses;
  • Testing the effectiveness of hearing screening during preschool years to detect hearing loss (particularly mild loss) that was missed during the newborn period; and
  • Learning more about the listening and communication abilities of infants and children with unilateral hearing loss.
