, which is currently used to determine the func tional hearing ability in adults or children with hearing loss treated with cochlear implantation, and provide recommendations as to how to generalize those characteristics into criteria that can be applied to other validated hearing tests for persons with cochlear implants. Although the chapter provides a description of the salient characteristics of the HINT, the committee believes that recommending how to generalize those characteristics to other validated tests is likely not the most useful question.

With that improvement, the relatively easy CID sentences fell out of favor due to ceiling effects exhibited in tests of cochlear implant recipients. In the 1990s the HINT sentences became the favored assessment for cochlear implantation.

Now, with the ongoing improvements in cochlear implants, the HINT is itself subject to the ceiling effects. The HINT sentences are based on the Bamford-Kowal-Bench (BKB)

In cases of unilateral HINT administration, the non-test ear may require masking so that individual ear performance is quantified. In addition to the standard materials and methods used in the development and validation of the HINT, several studies have administered the adaptive HINT via an eight-loudspeaker circumferential array with speech presented from 0 degrees and uncorrelated noise presented from all eight loudspeakers (e.g., Compton-Conley et al., 2004; Valente et al., 2006)

• Uses sentences • Adaptive assessment • Intelligible materials • Translated into multiple languages • Speech-spectrum noise • Recorded male speaker • Designed for co-located speech from the same azimuth • Relatively quick assessment • Difficult to obtain However, just as improvements in cochlear implant technology and surgical techniques warranted a change from CID to HINT sentences, recent improvements in these areas may warrant SSA re-evaluating its current use of the HINT.

In 1996, stakeholders from otolaryngology, audiology, hearing science, and cochlear implant manufacturers recommended a Minimum Speech Test Battery (MSTB) for cochlear implant candidacy and for assessment of post-operative performance.

It considers a person with hearing loss disabled until age 5, or for 1 year after initial cochlear implantation, whichever is later. After that period SSA requires speech recognition testing performed with any version of the HINT to determine whether the person's impairment meets requirements for disability (SSA Listing 2.11B and 102.11B)

. While that remains a feasible method for adaptive HINT administration, the measure still offers limited ecologic validity, given the use of a single male talker, well-articulated speech, and a steady-state background noise.
