“…Sensorineural hearing loss causes deterioration in speech recognition [34,35,36,37]. In contrast, SRSs in atretic ears are not very poor if the presentation level is su cient since the functions of the sensorineural system are maintained.…”

Gel is a conduction medium used to improve signal transmission and is applied in ultrasonography to obtain high-quality images; however, it is rarely used in hearing devices. The application of gel to couple the transducer to the ear could potentially improve the benefits of hearing aids, particularly cartilage conduction (CC) hearing aids, which deliver signals by vibration. The aim of this study was to investigate the impact of gel application on the efficacy of CC hearing aids in 23 patients (30 ears). The aided thresholds, maximum speech recognition scores (SRSs), and hearing level at which the maximum SRS was observed were compared before and after the application of gel to the transducer of CC hearing aids. Subjective impressions of hearing improvement, on applying the gel, were also evaluated. The aided thresholds above 1 kHz significantly improved on applying the gel to the transducer. The effectiveness of gel application was better for patients who reported improvement in hearing. The audiometric results were consistent with subjective evaluations. The application of gel has minimal risk, and its benefits can be verified easily with subjective evaluation. Gel application can be considered an effective option for improving the benefits of CC hearing aids.

“…Group delay created by filtering was removed by applying zero-phase filtering technique. These cutoff frequencies were purposefully chosen because they are the typical frequencies of residual hearing in individuals who utilize bimodal hearing ( Smith-Olinde et al, 2004 ; Jürgens et al, 2011 ; Bianchi et al, 2016 ; Patel and McKinnon, 2018 ; Varnet et al, 2019 ; Yoho and Bosen, 2019 ). Results from these chosen cutoff frequencies can be used for future comparison with data that will be measured in individuals with hearing aids and cochlear implants.…”

Dichotic spectral integration range, or DSIR, was measured for consonant recognition with normal-hearing listeners. DSIR is defined as a frequency range needed from 0 to 8,000 Hz band in one ear for consonant recognition when low-frequency information of the same consonant was presented to the opposite ear. DSIR was measured under the three signal processing conditions: (1) unprocessed, (2) target: intensified target spectro-temporal regions by 6 dB responsible for consonant recognition, and (3) target minus conflicting: intensified target regions minus spectro-temporal regions that increase confusion. Each consonant was low-pass filtered with a cutoff frequency of 250, 500, 750, and 1,000 Hz, and then was presented in the left ear or low-frequency (LF) ear. To create dichotic listening, the same consonant was simultaneously presented to the right ear or high-frequency (HF) ear. This was high-pass filtered with an initial cutoff frequency of 7,000 Hz, which was adjusted using an adaptive procedure to find the maximum high-pass cutoff for 99.99% correct consonant recognition. Mean DSIRs spanned from 3,198–8,000 Hz to 4,668–8,000 Hz (i.e., mid-to-high frequencies were unnecessary), depending on low-frequency information in the LF ear. DSIRs narrowed (i.e., required less frequency information) with increasing low-frequency information in the LF ear. However, the mean DSIRs were not significantly affected by the signal processing except at the low-pass cutoff frequency of 250 Hz. The individual consonant analyses revealed that /ta/, /da/, /sa/, and /za/ required the smallest DSIR, while /ka/, /ga/, /fa/, and /va/ required the largest DSIRs. DSIRs also narrowed with increasing low-frequency information for the two signal processing conditions except for 250 vs. 1,000 Hz under the target-conflicting condition. The results suggest that consonant recognition is possible with large amounts of spectral information missing if complementary spectral information is integrated across ears. DSIR is consonant-specific and relatively consistent, regardless of signal processing. The results will help determine the minimum spectral range needed in one ear for consonant recognition if limited low spectral information is available in the opposite ear.

“…The BIF in the SII model is not invariant; it varies with features of the target speech, such as the type of speech material ( DePaolis, 1996 ; Du et al , 2019 ), the availability of visual information ( Bernstein and Grant, 2007 ; Bernstein et al , 2020 ), and presentation level ( Calandruccio et al , 2016 ; Shen et al , 2020 ). Recent research also suggests that the BIF may vary from individual to individual ( Shen and Kern, 2018 ; Varnet et al , 2019 ; Yoho and Bosen, 2019 ; Shen et al , 2020 ). For speech recognition in masking sounds, the BIF also depends on whether the masker is broadband noise or competing speech ( Buss and Bosen, 2021 ).…”

Spectral weighting for sentence recognition in steady-state and amplitude-modulated noise

Spectral weights in octave-frequency bands from 0.25 to 4 kHz were estimated for speech-in-noise recognition using two sentence materials (i.e., the IEEE and AzBio sentences). The masking noise was either unmodulated or sinusoidally amplitude-modulated at 8 Hz. The estimated spectral weights did not vary significantly across two test sessions and were similar for the two sentence materials. Amplitude-modulating the masker increased the weight at 2 kHz and decreased the weight at 0.25 kHz, which may support an upward shift in spectral weights for temporally fluctuating maskers.
