Listening difficulty ratings, using words with high word familiarity, are proposed as a new
subjective measure for the evaluation of speech transmission in public spaces to provide …

Bone-conducted ultrasounds (BCUs) can be perceived by the profoundly deaf, who hardly
sense sounds even with conventional hearing aids, as well as normal-hearing subjects. A …

] showed that listening difficulty ratings can be used to evaluate speech transmission
performance more exactly and sensitively than intelligibility. Meanwhile, speech …

Ultrasound can be perceived through bone conduction by the profoundly deaf as well as by
normal-hearing subjects. Moreover, speech signals modulated onto ultrasound can be …

For ideal speech communication in public spaces, it is important to determine the optimum
speech level for various background noise levels. However, speech intelligibility scores …

Abstract Effects of auditory training with bimodal audio–visual stimuli on monomodal aural
speech intelligibility were examined in individuals with normal hearing using highly …

In this study, we investigated how the temporal envelopes contribute to the recognition of
isolated syllables, words, and sentences in noise-vocoded speech, under comparison with …

Objective To examine the feasibility and possible effects of in-home auditory training using
audiovisual speech stimuli on a tablet computer for patients with hearing loss using a …

The speech level of verbal information in public spaces should be determined to make it
acceptable to as many listeners as possible, while simultaneously maintaining maximum …

The acceptable range of speech level as a function of background noise level was
investigated on the basis of word intelligibility scores and listening difficulty ratings. In the …
