Ling, Madell, Hewitt (LMH) Test or Low, Mid, High (LMH) Test
The LMH test is used daily to assure that the hearing devices (i.e., cochlear implants, hearing aids, FM system, BAHA) are working properly. (Madell & Hewitt, n.d.)
EBP: Dan Ling developed the 5 sound test /a, e, u, sh, s/, then the /m/ was added to become the Ling 6 Sound Test. The test was developed to make sure that the patient hears all the sounds that are difficult to hear with their hearing devices. However, Madell and Hewitt added 4 additional phonemes to provide audiologist with additional information to adjust technology settings to access the frequency bands (Low, Mid, High) not being perceived (Madell, J., 2021).
(Madell & Hewitt, n.d.)
Goal: Daily, when presented with LMH sounds, the patient will independently identify or imitate the sound presented verbally with 100% accuracy each session as measured by self, communication partner and/or SLP.

Impairment: Adults/children with hearing loss with hearing devices.
Activity Breakdown
Step 1: A LMH sound would be said aloud by the clinician with the patient facing away from the clinician.
**That means wearing one hearing aid (left, right) at a time, then wearing both hearing aids.
Step 2: The patient will verbally repeat sound or point to written phoneme.
Step 3: Complete the steps above for all (right technology, left technology, binaural technology, FM system).
Step 4: Refer to the audiologist if any of the Low-Mid-High frequencies are not heard.
Hierarchy Cueing
Independently: The patient imitates or identifies the same sound.
