Purpose The objectives of the current study were to examine effect noise (−5 dB SNR) on auditory comprehension and its relationship with working memory. It was hypothesized that has a negative impact information processing, memory, comprehension. Method Children normal hearing between ages 8 10 years administered memory tasks in quiet noise. measure comprised 5 domains: main idea, details, reasoning, vocabulary, understanding messages. Results Performance significantly poorer than quiet....

Over the first years of life, brain undergoes substantial organization in response to environmental stimulation. In a silent world, it may promote vision by (i) recruiting resources from auditory cortex and (ii) making visual more efficient. It is unclear when such changes occur how adaptive they are, questions that children with cochlear implants can help address. Here, we examined 7-18 old children: 50 had implants, delayed or age-appropriate language abilities, 25 typical hearing...

Objective Previous research shows that cochlear implant users experience significant difficulty with speech perception in noisy listening situations.

Purpose This retrospective study used a cochlear implant registry to determine how performing speech recognition candidacy testing in quiet versus noise influenced patient selection, recognition, and self-report outcomes. Method Database queries identified 1,611 recipients who were divided into three qualifying groups based on preoperative perception scores (≤ 40% correct) the AzBio sentence test: group, +10 dB SNR +5 group. These evaluated for demographic hearing characteristics....

Speech recognition was evaluated for ten adults with normal hearing and eight Nucleus cochlear implants (CIs) at several different signal-to-noise ratios (SNRs) three frequency modulated (FM) system arrangements: desktop, body worn, miniature direct connect. Participants were asked to repeat Hearing in Noise Test (HINT) sentences presented speech noise a classroom setting percent correct word repetition determined. Performance both normal-hearing CI participants the desktop soundfield...

Speech recognition abilities of adults and children using cochlear implants (CIs) are significantly degraded in the presence background noise, making this an important area study assessment by CI manufacturers, researchers, audiologists. However, at time there a limited number fixed-intensity sentence tests available that also have multiple, equally intelligible lists noise. One measure speech recognition, AzBio Sentence Test, provides 10-talker babble on commercially compact disc; however,...

Previous research suggests that young children have significant difficulty recognizing speech in the presence of background noise as compared with older and adults. However, limited exists examines developmental effects recognition separate age groups children, especially a classroom setting. The lack may relate to number tests multiple, equally intelligible lists are also appropriate for children. As result, goals present study include investigating (1) (2) benefits spatial separation...
