HEARLab was developed by National Acoustic Laboratories and the HEARing CRC. It is a proven test instrument that enables the clinician to measure cortical or brainstem responses in people with and without hearing aids. The system uses a standard PC with a versatile electronic interface for stimulus presentation and response acquisition. The interface allows the software to fully control stimulus levels, signal pathways and response conditioning. This technology enables new audiological tests to be added to the HEARLab system easily, through the development of new software modules.

The first software module released is NAL-ACA, which is a hearing assessment module that provides two different types of assessments:

  1. Aided Cortical Assessment (ACA) enables the clinician to evaluate hearing aid fittings using real speech sound presented through a speaker. By measuring the evoked cortical responses of an infant, with or without hearing aids, it is possible to estimate the audibility of speech sounds by that infant.
  2. Cortical Threshold Estimate (CTE) is used to estimate unaided hearing thresholds. Tones are presented via insert earphone or a bone vibrator and the evoked cortical responses are automatically detected by HEARLab.

Two additional modules have been developed and are awaiting regulatory approval:


This module allows the clinician to measure brainstem responses.


This module allows the clinician to produce an audiogram at the touch of a button. The software will automatically present stimuli and measure the response to produce the audiogram.


For those with existing HEARLab software running on Windows XP, two new upgrade options are available:

  1. Upgrade the HEARLab software by adding the /s/ stimuli. The cost is AUD500.
  2. Upgrade the HEARLab software to Windows 7, including the addition of the /s/ stimuli. The cost is AUD750.

To purchase an upgrade, please email


Frye Electronics are no longer manufacturing HEARLab. The HEARing CRC is currently working to find a new manufacturer. Currently there are no HEARLabs available for purchase. We will update this website when the situation changes. Frye Electroncis can be contacted for spare parts and accessories.
