Objective:
To achieve a multi-dimensional characterisation of normal-hearing and hearing-impaired listeners' hearing abilities, including standard audiological conditions and virtual acoustic scenes for the evaluation of hearing aids.
Design:
Within-subjects design, including speech intelligibility and listening effort measurements in two standard conditions and four virtual acoustic scenes, and assessments of loudness scaling, tone-in-noise detection thresholds, and HEAR-COMMAND tool questionnaire.
Study Sample:
76 age-matched listeners, including 20 normal-hearing, 25 hearing-impaired without hearing aids, and 31 hearing aid users.
Results:
Speech intelligibility and hearing aid benefit in virtual acoustic scenes fell between the results of the standard audiological conditions S0N0 and S0N90. The S0N0 and underground station environment were the most challenging conditions regarding speech intelligibility and listening effort. The pure-tone average explained most of the differences between the listener groups in loudness perception and tone-in-noise detection thresholds. Moderate to strong correlations were found between the HEAR-COMMAND tool speech scores and speech intelligibility.
Conclusions:
The study established a unique measurement database including complex virtual acoustic scenes and demonstrated a connection between speech intelligibility, hearing aid benefit, and other perceptual auditory measures. The database and findings provide a valuable foundation for advancing hearing aid evaluation and can serve as a benchmark in computational audiology.

Perceptual Constancy
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
Virtual Work
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Normal Stress
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's important to...
