IHAB's SoundCompass is a testing system developed to scientifically and objectively assess the sense of sound direction.
Five to seven speakers are arranged in front of the patient to precisely measure horizontal-plane spatial perception, with the entire process — from presenting stimuli to collecting responses — fully automated.
Key Features
Fully Automated Testing
- Automates the entire process, from stimulus presentation to response collection
- Enables fast, convenient testing
Configurable Test Conditions
- Supports a range of settings tailored to test purpose and subject
- Offers flexible test configuration
Data-Driven Error Pattern Analysis
- Analyzes directional-perception error patterns from test results
- Supports optimizing hearing aid/cochlear implant settings and building tailored rehabilitation programs
Test Setup Adapted to the Booth
- 5–7 speakers arranged in front of the patient (customizable)
- Precisely measures horizontal-plane spatial perception
In-House Designed Speaker Mount
- A dedicated mount designed and built in-house for angular precision
- Improves the accuracy and reproducibility of the test environment
User-Friendly Touchpad Response
- Uses an intuitive touch-based response method
- Provides a testing environment accessible to children and older adults alike
Why does sound localization — 'hearing space' — matter?
- 01A core auditory function behind spatial awareness
- 02Used to locate speech, warning sounds, and approaching vehicles
- 03Linked to environmental-sound awareness and communication ability
- 04Directly tied to safety — walking, driving, and avoiding hazards
- 05A key indicator for asymmetric hearing loss, sensorineural hearing loss, and auditory processing disorder
Key Features for Clinical Use
- Provides an intuitive results report for clinicians
- Offers sound-localization metrics based on international standards
- Automatically grades sound-localization impairment using the ICF Framework
