Disease relevance of Hearing Aids


Psychiatry related information on Hearing Aids

  • The present study assessed the clinical features of hearing and some aspects of language development in congenital deafness due either to GJB2 mutations or to other factors in Japanese patients who had been habilitated with hearing aids [6].
  • OBJECTIVE: This article presents the underlying rationale, normative data, and reliability data for a test of loudness perception (the Contour Test) that was devised for use in clinical hearing aid fitting [7].
  • Previous findings that sensorineural hearing loss and reduced speech discrimination adversely influenced hearing aid wear were attributed to differences in amount of loss and other intervening psycho-socio-vocational variables [8].
  • It was suggested that the range of individual differences renders any group mean MCL too imprecise a measure for selecting and prescribing a hearing aid, or for determining the effect that aid may have on an individual's performance [9].

High impact information on Hearing Aids

  • In randomized trials, hearing aids have been demonstrated to improve outcomes for patients with sensorineural hearing loss [10].
  • Patients using a hearing aid received tacrolimus more frequently than cyclosporine (P < 0.05) [11].
  • The present results establish the basis for future studies to aid in the evaluation and follow-up of patients with congenital hearing loss associated with GJB2 mutations who are habilitated with hearing aids [6].
  • The criteria were based on data from 135 evaluations of 50 children using cochlear implants with monosyllabic words, open-set sentences, the Clinical Evaluation of Language Fundamentals, and the Peabody Picture Vocabulary Test. Data from 114 evaluations of 43 children using hearing aids were used to illustrate the sensitivity of the criteria [12].
  • DESIGN:: Speech and several common nonspeech hearing aid test signals, matched at overall root-mean-square levels corresponding to average (65 dB SPL) and loud (80 dB SPL) conversational speech, were input into a master hearing aid circuit, and the gain of the circuit was measured in one-third octave bands [13].

Chemical compound and disease context of Hearing Aids


Biological context of Hearing Aids


Anatomical context of Hearing Aids

  • Patients with skin penetrating titanium implants in the temporal bone, for attachment of bone-anchored hearing aids, have made it possible to investigate the free-damped natural frequencies (resonance frequencies) of the human skull in vivo [19].
  • With the probe tube in the ear canal, a hearing aid alone is measured with a 60 dB SPL input and the FM system attached to the hearing aid (personal FM system) is assessed with an 80 dB SPL input to account for the higher input levels that occur due to the 6 inch distance between the speaker's mouth and the FM microphone [20].
  • Complete audiologic evaluation may prove to be uniquely helpful both in establishing a diagnosis by recognizing the characteristic patterns of stapes fixation and in planning for the surgical, medical, or hearing aid management of the patient with otosclerosis [21].
  • INTRODUCTION: The bone-anchored hearing aid (BAHA) system uses an osseointegrated titanium implant to propagate sound directly to the inner ear through the bones of the skull, bypassing the impedance of the skin and subcutaneous tissues [22].
  • We report our experience with titanium implants for extra-aural rehabilitation in the mastoid region with a bone-anchored hearing aid (BAHA) and auricular prosthesis [23].

Associations of Hearing Aids with chemical compounds


Gene context of Hearing Aids

  • The OSCAR-project (Optimal Speech Communication Assistance for Residual Abilities) within the TIDE frame is aiming at processing the speech signal in such a way so that it can be more effectively aurally perceived than with an ordinary hearing aid in case of a very small residual hearing [28].
  • OBJECTIVE: To compare the benefits provided to patients with sensorineural hearing loss by 3 commonly used hearing aid circuits [29].
  • In Experiment II, the largest differences between traditional probe microphone measures of SPL and predicted measures were noted when hearing aid gain was 0 dB and large negative RECD values were present [30].
  • METHODS: Fifty adults aged over 60 who were supplied with an NHS hearing aid had their hearing handicap and communication function recorded at initial hearing aid assessment, and after three months of aid use [31].
  • However, because childhood otosclerosis is rare and children commonly choose to use hearing aids in lieu of undergoing surgery, little outcome data are available [32].
