Ling 6(HL) Test

The Ling 6(HL) test (v2.0) provides calibrated, pre-recorded Ling 6 sounds (m, u, a, i, sh, s) for use in measuring unaided or aided thresholds. They are typically used to measure aided thresholds for hearing aids, bone anchored hearing devices, or other assistive hearing technologies.

The Ling-6(HL) test includes level corrected stimuli allowing for speech sound detection threshold evaluation in dB HL. It was originally developed and validated with adult listeners (Scollie et al., 2012). A follow-up study, including active collaboration from pediatric audiologists across Canada, evaluated and refined the tool for use in pediatric hearing aid outcome measurement using an integrated knowledge translation framework (Glista, Scollie, Moodie, Easwar & The Network of Pediatric Audiologists of Canada, 2014). The Ling 6(HL) Test can be run using clinically available equipment, such as a CD player and commercial audiometer. The test includes a CD with eight tracks including a calibration tone to adjust the VU meter of an audiometer, calibration noise to ensure sound field calibration, and six stimuli corresponding to the Ling 6 phonemes (/m/), /u/, /a/, /i/, /sh/ and /s/).

Potential Applications

Test provides a valid approach for measuring aided and/or unaided speech detection thresholds instead of pure-tones

Includes sound field stimulus calibration in dB HL, allowing for repeatability, scoring and interpretation of test results

Aided thresholds can be measured to compare performance across different hearing aid conditions or with other assistive devices

Testing set-up instructions are provided along with scoring tools. This includes an audiogram that has been preconfigured to include normative performance ranges for adult and child listeners, as well as typical aided performance ranges for children with hearing loss ranging from mild to severe.
