Interventional
Description of intervention(s) / exposure
Other interventions - Provision of standard audiological + fNIRS test results
Other interventions - Provision of standard audiological test results only

Experimental: Provision of standard audiological + fNIRS test results - The treatment arm involves the provision of additional fNIRS sound detection and speech discrimination test results to the audiologists, in addition to standard audiology information. Standard information includes:
At diagnosis: unaided Auditory Brainstem Response results;
After initial hearing aid provision: as a) above plus aided Cortical Evoked Potentials;
After hearing aid program is adjusted to satisfaction: as b) above plus parent observational report, PEACH (2);
After initial cochlear implant programming: behavioural observations.

Active Comparator: Provision of standard audiological test results only - The standard audiology information available to the audiologists includes:
At diagnosis: unaided Auditory Brainstem Response results;
After initial hearing aid provision: as a) above plus aided Cortical Evoked Potentials;
After hearing aid program is adjusted to satisfaction: as b) above plus parent observational report, PEACH (2);
After initial cochlear implant programming: behavioural observations.


Other interventions: Provision of standard audiological + fNIRS test results
Infants with hearing loss will be tested using functional near-infrared spectroscopy (fNIRS) and a patented analysis algorithm to measure sound detection and discrimination. Their standard audiological test results will also be collected from their audiology service provider/s. Both sets of test results will be given to the participating audiologists in the experimental arm.

Other interventions: Provision of standard audiological test results only
The provision of test results to the audiologist will be the same as in the experimental arm, but without the fNIRS test results included.

Eligibility
Key inclusion criteria
The above eligibility applies to the participating audiologists who are in the experimental
and control arms of the study

Audiologist

- Is a qualified audiologist who meets the criteria for membership of Audiology
Australia.

- Has at least 1 year of experience in paediatric diagnostic, hearing aid or cochlear
implant audiology service provision in Australia.

- Provides a signed and dated informed consent form.

Audiologist

Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion criteria (only for a specific infant test result):

- Is the managing audiologist for the infant who's results are being provided.

Infants are also recruited into the study to have an fNIRS assessment performed. They do
not participate further after the fNIRS test.

Infant Inclusion criteria:

- Between the ages of 1 and 24 months at the time of fNIRS testing.

- Has permanent hearing loss in one or both ears as determined by audiological
diagnostic testing.

- Has a legally acceptable representative capable of understanding the informed consent
document and providing consent on the participant's behalf.

Infant

- There are no exclusion criteria other than not meeting the inclusion criteria.

Summary
Brief summary
The goal of this clinical trial is to find out whether hearing test results using functional
near-infrared spectroscopy (fNIRS) will help to fast-track early intervention for infants
born with a hearing loss. fNIRS is a method of imaging brain activity using light. The main
questions are:

1. Can audiologists make more confident decisions about the optimal interventions at
different critical points in the hearing care pathway when they are given additional
fNIRS information compared to when they have standard audiology test results alone?

2. Is the experience of their infant having an fNIRS test acceptable and comfortable for
the parents or care givers?
