Use of frequency transposition in a thin-tube open-ear fitting

The effect of using integrated signal processing hearing aids on the speech recognition abilities of hearing impaired Arabic-speaking children

“…An exception to this are a group of researches which were directed to study frequency transposition in integrated HAs. 32,2,24,3,33 These studies reported an improvement in the identification of voiceless consonants, especially fricatives, in adult and children users which may be attributed to the regain of high frequency information that includes some voiceless fricatives such as /f/, /s/ and /sh/. 37 Information transmission analysis for vowels showed that both vowel duration and vowel place were equally transmitted through both hearing aids (Tables 6 and 7).…”

The contribution of a frequency-compression hearing aid to contralateral cochlear implant performance

“…Only frequencies within the source octave of 2f e to 2.7f e are lowered and frequencies below f e are left unprocessed. Kuk et al (2007) studied the effect of frequency transposition via the Widex Audibility Extender on consonant and vowel perception and subjective preference ratings for 13 adults with high-frequency hearing loss. The subjects were fit with hearing aids bilaterally that were programmed with and without frequency-lowering in two memories.…”

Perceived Occlusion and Comfort in Receiver-in-the-Ear Hearing Aids

“…In fact, acoustic stimulation may actually distort sounds and lead to poorer speech understanding. Therefore, patients with this degree of hearing loss are also not ideal candidates for this type of fitting (Kuk, Peeters, Keenan, and Lau, 2007).…”

“…Therefore, clinicians may fit patients with RITE devices paired with small, open domes who have low frequency hearing losses that exceed a mild degree. In such cases, patients who may in fact benefit from additional low frequencies may not always receive adequate amplification since open fittings do not provide gain at frequencies below 1 kHz (Kuk, Peeters, Keenan, & Lau, 2007). Whether or not various standard domes in conjunction with RITE aids result in an intolerable degree of self-perceived occlusion and/or discomfort in hearing-impaired, older adults, has not been adequately answered in the literature thus far.…”

“…Kuk et al, 2007). Whether or not various standard domes in conjunction with RITE aids result in an intolerable degree of self-perceived occlusion and/or discomfort in hearing-impaired, older adults has not been adequately answered in the literature thus far.The occlusion effect refers to a sound quality people may notice when wearing hearing aids.…”
