The purpose of the present investigation was to determine whether differences exist in audiometric hearing status between individuals with and without multiple sclerosis (MS) and between individuals with relapsing-remitting MS (RRMS) and individuals with secondary progressive MS (SPMS). Forty-seven subjects with MS (26 with RRMS and 21 with SPMS) and forty-nine control subjects without MS compl...

BACKGROUND Construction workers are at risk of noise-induced hearing loss (NIHL) but often have no periodic audiometric testing. METHODS The participants were construction workers assessed for Hand-Arm Vibration Syndrome (HAVS) at the Occupational Health Clinic, St. Michael's Hospital, Toronto, Ontario. Audiometry was offered and 169 of the 191 workers assessed for HAVS agreed to have the aud...

Objective: To evaluate the effects of chloroquine phosphate on cochlear function using clinical and audiometric studies when administered in regular doses and in the recommended regimens, for the treatment of malaria. Study design and setting: Prospective, cohort, observational study, with convenience sampling, in a tertiary care hospital. Methodology: All subjects proved or presumed to be suff...

Abstract Subjective cognitive decline (SCD) impacts quality-of-life, healthcare utilization and predicts dementia. If hearing loss is associated with SCD unknown. We estimated the cross-sectional association between in 2,536 participants (79.3±4.4 years, 60% female, 20% Black) Atherosclerosis Risk Communities Neurocognitive Study. was defined as self-reported persistent memory (yes/no) among ad...

introduction carhart's notch (cn) is a major audiometric criterion for diagnosis of otosclerosis; it is an abnormal audiometric pattern due to fixation of stapes and relative reduction in perilymphatic motion. methods 130 patients (146 diseased ears) were evaluated in this study. audiometric tests were performed for each patient 2 weeks before and 6 month after surgery, and the average decline ...

Audiometric thresholds and otoacoustic emissions (OAEs) were measured in 285 U.S. Marine Corps recruits before and three weeks after exposure to impulse-noise sources from weapons' fire and simulated artillery, and in 32 non-noise-exposed controls. At pre-test, audiometric thresholds for all ears were <or=25 dB HL from 0.5 to 3 kHz and <or=30 dB HL at 4 kHz. Ears with low-level or absent OAEs a...

Draft ANSI S12.13 1991 Standard Evaluating the Effectiveness of Hearing Conservation Programs presents statistical protocols purportedly sensitive to temporary threshold shift (TTS) in occupational hearing conservation program (HCP) audiometric databases. Because it is well established that less TTS is found in humans with hearing loss than in those with essentially normal hearing, one might pr...
