Abstract
OBJECTIVE: To investigate the validity and reproducibility of a newly developed internet-based self-administered hearing test using clinical pure-tone air-conducted audiometry as gold standard. STUDY DESIGN: Cross-sectional intrasubject comparative study. SETTING: Karolinska University Hospital, Solna, Sweden. PATIENTS: Seventy-two participants (79% women) with mean age of 45 years (range, 19-71 yr). Twenty participants had impaired hearing according to the gold standard test. INTERVENTIONS: Hearing tests. MAIN OUTCOME MEASURES: The Pearson correlation coefficient between the results of the studied Internet-based hearing test and the gold standard test, the greatest mean differences in decibel between the 2 tests over tested frequencies, sensitivity and specificity to diagnose hearing loss defined by Heibel-Lidén, and test-retest reproducibility with the Pearson correlation coefficient. RESULTS: The Pearson correlation coefficient was 0.94 (p

Abstract
to investigate auditory function in subjects with early Alzheimer's disease, mild cognitive impairment and with subjective memory complaints, in search of signs of central auditory processing dysfunction even in early stages of cognitive impairment.
a consecutive group of men and women, referred to the Memory Clinic at the Karolinska University Hospital, was approached for inclusion in this prospective study. One hundred and thirty-six subjects, mean age 64 years (range 50-78 years), diagnosed with Alzheimer's disease (n = 43), mild cognitive impairment (n = 59) or with subjective memory complaints (n = 34), were included.
auditory function was assessed with pure tone audiometry, speech perception in quiet and in background noise and dichotic digits tests with two or three digits.
pure tone audiometry and speech perception scores in quiet and in background noise were normal for age and without between-group differences. Dichotic digits tests showed strongly significant differences between the three groups, where the Alzheimer's disease group performed significantly poorer than the other two groups, with the mild cognitive impairment group in an intermediate position.
our results demonstrate that central auditory processing dysfunction is highly evident in subjects with Alzheimer's disease, and to a considerable extent even in subjects with mild cognitive impairment.

Abstract
As the proportion of older people increases, it is important to investigate hearing acuity in older individuals and to calculate hearing decline for older ages, using standardised test protocols. The main aim of this study was to determine pure-tone hearing thresholds in an unscreened birth cohort of 85-year-olds born in 1930, living in an industrial Swedish city. A further aim was to describe hearing decline in men and women from 75 to 85 years of age with the aid of longitudinal data. The study was part of the Gothenburg H70 Birth Cohort Studies in Sweden. Hearing thresholds (0.25-8?kHz) were measured using automated pure-tone audiometry for 286 85-year-old participants. A subsample (n?=?182) was hearing examined at 75 years of age and studied longitudinally from 75 to 85 years. At age 85 years, men had better hearing at low frequencies but poorer hearing at high frequencies than women. The longitudinal study showed a considerable decline between 75 and 85?years?at mid-high frequencies (>1?kHz) and the amount of decline was similar between sexes. The results contribute to the estimation of the future need for hearing health services.

Abstract
To analyze time trends in prevalence of hearing impairment in almost complete birth cohorts of 18-year old Swedish men from 1970s up to 2010.
Before 1999, all 18-year old men, in Sweden, were called for a compulsory conscription examination. In 1971-1999, the participation rate in audiometry was 73-95%. After 1999, when exemption from conscription was allowed, the participation rate gradually declined to 52% in 2004. Samples with participation rates below 50% (2005-2010) were considered non-representative and excluded from the analyses.
High-frequency hearing impairments (HFHI) 35-40 dB HL and =45 dB HL showed a decreasing trend over the observed period, from a prevalence of 2.9% (35-40 dB HL) and 3.8% (=45 dB HL) respectively in 1971 to 1.4% and 1.1% respectively in 2004. HFHI 25-30 dB HL, showed slow variations over time and decreased from 8.5% in 1971 to 3.2% in 1981 followed by an increase to 10.4% in 1992. After that year there was a decrease to 5.2% in 2004. The slow fluctuations affected only HFHI 25-30 dB HL, mainly at 6 kHz. The left ear was more affected than the right ear.
The most important observation was a decrease of HFHI 35-40 dB HL by 52% percent and of HFHI =45 dB HL by 71% between the years 1971 and 2004. The prevalence of HFHI 25-30 dB HL in young Swedish males fluctuated over a period of 33 years. Possible reasons for these trends and variations are discussed.

Abstract
A revised hearing conservation program (HCP) was implemented in the Swedish Armed Forces in 2002. The aim of this study was to evaluate the incidence of significant threshold shifts (STS) in male conscripts heavily exposed to noise after the implementation of the new HCP, comparing the results to those of an earlier study from 1999/2000.
The study was prospective and longitudinal, covering the period from reporting to military service to discharge. The outcome measure was the incidence of STS. Statistics from the military insurance system was analysed.
A total of 395 conscripts were included in the study (mean age 19 years). The control group (n: 839) consisted of men of the same age.
In 2004/2005 the incidence rate of STS was 2.3% compared to 7.9% in 1999/2000 and compared to 3.7% among the controls. The number of cases of auditory complications reported from conscripts to the insurance system has decreased, from 16 to 5/100,000 days of military training, during the last decade.
The new HCP apparently reduced the incidence rate of STS to one third compared to before the program was introduced and leveled it to the incidence rate in the control-group not exposed to military noise.

Abstract
In military outdoor shooting training, with safety measures enforced, the risk of a permanent, noise-induced hearing loss is very small. But urban warfare training performed indoors, with reflections from walls, might increase the risk. A question is whether antioxidants can reduce the negative effects of noise on human hearing as it does on research animals. Hearing tests were performed on a control group of 23 military officers before and after a shooting session in a bunker-like room. The experiments were repeated on another group of 11 officers with peroral adminstration of N-acetyl-cysteine (NAC), directly after the shooting. The measurements performed were tone thresholds; transient-evoked otoacoustic emissions, with and without contralateral noise; and psycho-acoustical modulation transfer function (PMTF), thresholds for brief tones in modulated noise. Effects from shooting on hearing thresholds were small, but threshold behavior supports use of NAC treatment. On the PMTF, shooting without NAC gave strong effects. Those effects were like those from continuous noise, which means that strict safety measures should be enforced. The most striking finding was that the non-linearity of the cochlea, that was strongly reduced in the group without NAC, as manifested by the PMTF-results, was practically unchanged in the NAC-group throughout the study. NAC treatment directly after shooting in a bunkerlike room seems to give some protection of the cochlea.

Abstract
Noise is a common exposure in the occupational work environment. Earlier studies of occupational noise and pregnancy outcome are few and show mixed results. To investigate if objectively assessed exposure to occupational noise during pregnancy is associated with reduced intrauterine growth and/or preterm birth a nationwide cohort study of 857,010 single births was initiated. Individual information on occupation and risk factors was retrieved from prenatal care interviews at pregnancy week 10. Occupational noise was classified into three exposure categories 85?dBA by a job exposure matrix. Odds ratios were adjusted for BMI, smoking, parity, education, physically strenuous work and low job control. Exposure to high (>85?dBA) levels of occupational noise throughout the pregnancy (full time workers) was associated with an increased risk of the child being born small for gestational age, OR 1.44 (95% CI 1.01 to 2.03) compared to noise exposure 21?days (median). In summary, full-time exposure to high levels of noise during pregnancy was associated with a slightly reduced fetal growth but not with preterm birth. The effect of intermediate occupational noise exposure (75-85?dBA) showed a small, but statistically increased risk for all studied birth outcomes. The study strengthens the evidence that pregnant women should not be long-term exposed to high levels >85?dBA of occupational noise during pregnancy. Intermediate exposure should be studied further.

Abstract
The demands/needs for audiological/otological services under optimal conditions were investigated within the framework of three epidemiological investigations. The study population consisted of 559 people, 318 women and 241 men, 70-91 years old. The participants were offered audiological and otological services, including hearing aid fitting. Fifteen per cent of the participants asked for audiological/otological services. Six per cent of the participants were equipped with hearing aids as a result of the study. Almost all of those with severe hearing loss either had been equipped with hearing aids prior to the study, or took advantage of the offer to get such devices. This figure represented about half of those with moderate hearing loss and about 20% of those with mild hearing loss. After the study, 19% were equipped with hearing aids, but in all 25% had hearing aids or had expressed a wish to get one. The percentages of elderly people with mild-to-moderate hearing loss, who contemplated purchasing an aid, but did not do so, were large, between 10%, and 22%. More than 11% consulted a doctor when the opportunity was offered to them. Most of them wanted the consultation because of progressive hearing loss. Middle ear disease was another important reason for a consultation.

Abstract
The aim of this study was to compare auditory functions and to analyse the prevalence of hearing impairment and the relationship of self-reported hearing disability with audiometric test results among 75-year-old people in three Nordic localities. The representative samples came from Glostrup, Denmark (n = 571), Göteborg, Sweden (n =450), and Jyväskylä, Finland (n =388). The median pure-tone thresholds were rather similar in all three populations. The prevalence of moderate hearing impairment varied between 26% and 34% in men, and between 17% and 23% in women. The corresponding figures in the prevalence of self-reported hearing difficulties were 41%-57%, and 28%-37%. The self-reported difficulties were broadly in accordance with the audiometric test results, but there also were individuals with conflicting results. It is concluded that the prevalence of hearing impairment in the three Nordic localities is fairly similar. To assess hearing disorders in elderly people, both audiometry and self-report data are needed.

Abstract
In the present retrospective register study a very large data base consisting of screening audiograms obtained at military conscription of 18-year-old Swedish men was used. The study group comprised 450,175 men, aged 18 years, tested at conscription to military service. There were nine age groups covering a 24-year period, from 1971 to 1995. This database was compared with a number of different pre- and postnatal factors with possible influence on the hearing function. This ecologic methodology gives tentative clues (but no proof) of possible ototraumatic influences. The hearing capacity was fairly similar during the entire span of the study and only small variations were observed. There was a slight tendency of better hearing capacity in the later age groups, compared with the earlier ones. The mean thresholds of the frequencies 4 and 6 kHz were slightly elevated in 1971, 1976 and, to some extent also in 1992. We tried to calculate the levels of leisure noise exposure during the study period. There was no apparent tendency of reduced noise levels, on the contrary the noise levels seemed to increase. The treatment programmes for acute otitis media (AOM) underwent considerable changes during the period from the early fifties to the early eighties, when the participants were pre-school children. One possible explanation for the slight improvement of the hearing capacity could be less ototraumatic influence of AOM. Data about the occurrence of four common epidemic diseases, covering the periods preceding and succeeding the years when the participants were born indicated that influenza and possibly pertussis (whooping cough), constitute putative prenatal risk factors for mild to moderate high frequency hearing loss.
