The Better hEAring Rehabilitation (BEAR) project aims to provide a new clinical profiling
tool—a test battery—for hearing loss characterization. Although the loss of sensitivity can
be efficiently measured using pure-tone audiometry, the assessment of supra-threshold
hearing deficits remains a challenge. In contrast to the classical “attenuation-distortion”
model, the proposed BEAR approach is based on the hypothesis that the hearing abilities
of a given listener can be characterized along two dimensions, reflecting independent
types of perceptual deficits (distortions). A data-driven approach provided evidence for
the existence of different auditory profiles with different degrees of distortions. Ten tests
were included in a test battery, based on their clinical feasibility, time efficiency, and
related evidence from the literature. The tests were divided into six categories: audibility,
speech perception, binaural processing abilities, loudness perception, spectro-temporal
modulation sensitivity, and spectro-temporal resolution. Seventy-five listeners with
symmetric, mild-to-severe sensorineural hearing loss were selected from a clinical
population. The analysis of the results showed interrelations among outcomes related to
high-frequency processing and outcome measures related to low-frequency processing
abilities. The results showed the ability of the tests to reveal differences among individuals
and their potential use in clinical settings.
