Direct drive hearing devices, which deliver a signal directly to the middle ear by vibrating the tympanic membrane via a lens placed in contact with the umbo, are designed to provide an extension of audible bandwidth, but there are few studies of the effects of these devices on preference, speech intelligibility, and loudness. The current study is the first to compare aided speech understanding between narrow and extended bandwidth conditions for listeners with hearing loss while fitted with a…

TLDR
This study establishes a speech recognition process that accurately outputs the speech-related semantics and proves that the method based on deep learning solves the problem of low accuracy of the traditional translation system.

Speech recognition, loudness, and preference with extended bandwidth hearing aids for adult hearing aid users

TLDR
The results suggest that providing the maximum bandwidth available with modern hearing aids fitted with DSL v5.0, using targets from 0.25 to 8 kHz, can be beneficial for the tested population.

Investigation of Extended Bandwidth Hearing Aid Amplification on Speech Intelligibility and Sound Quality in Adults with Mild-to-Moderate Hearing Loss.

TLDR
It is demonstrated that a pair of currently available extended bandwidth hearing aids was technically capable of delivering high-frequency amplification that was both audible and useable to listeners with mild-to-moderate hearing loss and was of acceptable sound quality.

Sound Quality Ratings of Amplified Speech and Music Using a Direct Drive Hearing Aid: Effects of Bandwidth

TLDR
The direct drive system provides higher sound quality of both speech and music compared to narrowband conditions, and stimuli with specific high-frequency content were rated with higher soundquality when additional high- frequency energy was present.

High-frequency audibility: the effects of audiometric configuration, stimulus type, and device.

TLDR
Estimating the maximum audible frequency by estimating the frequency where the speech spectrum intersects the audiogram in the high frequencies can assist clinicians in making decisions about which device or configuration of devices provides the greatest access to high-frequency information, as well as whether frequency-lowering technology should be used.

Achieved Gain and Subjective Outcomes for a Wide-Bandwidth Contact Hearing Aid Fitted Using CAM2

TLDR
Most participants preferred slightly less gain at 6 to 10 kHz than prescribed for experienced users by CAM2, preferring similar gains to those prescribed for inexperienced users, but gains over the extended high frequencies were high relative to those that are currently available with acoustic hearing aids.

Effects of Amplification and Hearing Aid Experience on the Contribution of Specific Frequency Bands to Loudness

TLDR
The results suggest that amplification causes high frequencies to have a larger contribution to overall loudness compared with listeners with normal hearing, and the high frequencies seem to dominate loudness perception in listeners with SNHL using hearing aids as they do in viewers with NH.

High-frequency amplification and sound quality in listeners with normal through moderate hearing loss.

TLDR
Results revealed that preference for either the wider or narrower bandwidth was correlated with the slope of hearing loss from 4 to 12 kHz, with steep threshold slopes associated with preference for narrower bandwidths.

TLDR
High-frequency amplification significantly improved objective performance in noise and subjective preference in quiet for listeners with varying degrees of mild-to-severe high-frequency hearing loss and dispensers should be aware that high- Frequency Amplification should, at least initially, be provided to the affected high- frequencies when mild- to-severe hearing loss is present.

The Benefits of Increased Sensation Level and Bandwidth for Spatial Release From Masking

TLDR
Performance for all listeners, regardless of age or hearing loss, improved with an increase in overall SL and/or bandwidth, but the improvement was small relative to the benefits of spatial separation.

Paired comparisons of nonlinear frequency compression, extended bandwidth, and restricted bandwidth hearing aid processing for children and adults with hearing loss.

TLDR
Preference for EBW can be limited for those with greater degrees of hearing loss, but participants with greater hearing loss may be more likely to prefer NFC.
