Filter by:In 1986 The Medical Research Council estimated that 4 million UK adolescents were at risk of hearing damage from over-exposure to loud music from personal audio players (PAPs), gigs, clubs, pubs and festivals. Since that time social noise exposure is estimated to have tripled to 19% of young people. The European Commission commissioned a report that estimated 5-10% of personal audio player users are risking permanent hearing loss and tinnitus by listening to music at high volumes for more than 1 hour a day for 5 years or more. Up to 246 million PAPs were sold in Europe in 2008, and 200 million mobile phones, many of which now have built-in audio players. Nevertheless, a recent survey showed that only 8% of young people identify hearing loss as a health problem. The Royal National Institute for the Deaf (RNID) undertook two surveys of young people in the UK to analyse listening behaviours as part of their "Don't Lose the Music" campaign. As a consequence they offer listening advice given by flyers at events and online at the dedicated website. There have been no studies to confirm if such advice is effective in reducing noise exposure. Aim: This study will pilot a methodology for a randomised controlled trial to test the effectiveness of a publically-available online video in changing the listening habits of young music lovers i.e. reduce the volume and number of hours of exposure. Hypothesis: A video and adapted sound track demonstrating the experience of noise-induced hearing loss and tinnitus accessed online will change the listening habits of 18-25 year-olds.
There are different kinds of ear tubes that may be inserted into the tympanic membrane to relieve recurrent acute otitis and hearing impairment due to otitis media with effusion. The tubes differ in size, shape and material. No-one knows if there are differences between the different kinds of tubes regarding complications. The investigators' hypothesis is that there is differences between the different kinds of tubes regarding complications. To test the investigators' hypothesis, the investigators are about to conduct a randomized controlled study of four kinds of tubes having two different material and two different shapes.
Noise-induced hearing loss (NIHL) is a significant clinical, social, and economic issue. Studies in animals have allowed us to identify mechanisms contributing to NIHL, including direct mechanical trauma, free radicals formed in association with metabolic stress, and reduced blood flow. A combination of antioxidant vitamins (beta-carotene, and vitamins C and E) and the mineral magnesium (which acts in part as a vasodilator but also as an antioxidant) is highly effective in preventing NIHL in animals. These studies evaluate efficacy of this intervention in humans. Hypothesis: Treatment with these micronutrients provides safe, effective attenuation of acute hearing changes induced by exposure to real-world sounds producing temporary (non-permanent) or permanent hearing changes induced by exposure to real-world sounds. Experiment 1: "Digital Audio Player" studies (University of Florida, Gainesville). Prevention of *temporary* elevations in hearing thresholds, induced by exposure to moderately loud music, will be measured. Subjects will be 70 young adults with equal numbers of male and female participants. Experiment 2: "Urban warfare" military studies (Karolinska Institutet, Sweden). Prevention of *temporary* elevations in hearing thresholds, induced by automatic gunfire sound inside a concrete bunker, will be measured. Subjects will be 31 adult male or female officers in the Swedish army required to participate in urban combat training regardless of study participation. All subjects are required to wear standard hearing protection during combat exercises.
The purpose of the study is to determine whether AM-111 is effective in the treatment of acute inner ear hearing loss (acute sensorineural hearing loss, ASNHL).
Disequilibrium between acid and base in the inner ear was suggested to be an important factor leading to hearing impairment associated with SLC26A4 mutations. For acid-base homeostasis in the inner ear, gastric-type proton pumps might demonstrate antagonistic effects to pendrin, the protein encoded by SLC26A4. To investigate whether proton pump inhibitors might prevent or treat acute fluctuating hearing loss related to SLC26A4 mutations, we launch the current double-blind randomized clinical trial.
The purpose of this clinical study is to determine the effectiveness of low level laser light therapy when applied around the head and ears in improving unaided word recognition in ears with sensorineural hearing loss.
The LittlEARS Auditory Questionnaire is designed to assess the development of the auditory behavior in children during the first two (hearing) years. The questionnaire has been validated on children with normal hearing whose native language is German. A comparison was made between North American English speaking children with normal hearing and found that it was consistent with the German data. This study is to validate the questionnaire in children with cochlear implants.
The purpose of this study is to evaluate and document longitudinal efficacy in young children implanted bilaterally with MED-EL COMBI 40+ / PULSARCI100/SONATATI100 cochlear implant systems.
This study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weaknesses) who have received cochlear implants.
The purpose of this study is to investigate the rate of false-positive results in Newborn Universal Hearing Screening Programs and it´s possible causes.
