Action potential threshold elevation in the guinea-pig as a function of impact noise exposure energy
- 1988
-
Ingår i: Audiology. - : Informa UK Limited. - 0020-6091. ; 27:6, s. 356-366
-
Tidskriftsartikel (refereegranskat)abstract
- Eighteen groups of guinea pigs were exposed to a simulated impact noise for periods of 1.5-24 h. The peak level was kept constant at 131.5 dB and the repetition rate was varied to give seven different equivalent levels (Leq) between 96 and 117 dB. The auditory thresholds were assessed by electrocochleography after 1 month and compared with those of a control group. Significant damage occurred even at the lowest exposure energy used. When the total exposure energy was expressed on a decibel scale, the threshold elevation (1-10 kHz) increased 1.07 dB for each decibel increase in the exposure energy, regardless of the combination of Leq and exposure time. The results of the study thus support the equal-energy hypothesis under these conditions.

Tidskriftsartikel (refereegranskat)abstract
- Hearing in elderly people was investigated in an epidemiological longitudinal study (H70) encompassing a cohort representative of an urban Swedish population born in 1901-02. The participants in the study were followed audiometrically over a 20-year period from 70 to 90 years of age. This study focused on hearing and its decline during the later time span in which the participants were tested at the age of 85, 88 and 90 years. The results revealed that hearing loss in advanced age progressed only slightly in both men and women. The annual hearing threshold decline was about twice as large in the eighth decade of life as compared with the ninth. Hearing function was similar in the respondents tested at the out-patient clinic and in those tested at home. There were no consistent indications that survivors to a great age showed better hearing at entry to the study at 70 years of age. Some gender differences were found and are discussed.

Speech recognition and just-follow-conversation tasks for normal-hearing and hearing-impaired listeners with different maskers
- 1994
-
Ingår i: Audiology. - : Informa Healthcare. - 0020-6091. ; 33:3, s. 165-176
-
Tidskriftsartikel (refereegranskat)abstract
- Speech recognition (SRT) and just-follow-conversation (JFC) tasks were performed by normal-hearing and hearing-impaired listeners matched for age and sex using three masking backgrounds: speech spectrum random noise, continuous forward speech and reversed speech. In the SRT task, the signal-to-noise (S/N) ratio for 50% correctly repeated words of short, 5-word, low-redundancy sentences was determined. In the JFC task, the listener adjusted the speech level until he felt he could just understand what was being said. The listeners needed a higher S/N ratio for the JFC task than for the SRT task. The speech maskers gave less masking than the random noise. No difference between forward and reversed speech was observed. The hearing-impaired listeners needed a higher S/N ratio than the normal-hearing subjects. Correlations between results obtained with the SRT and the JFC techniques were significant with speech but not with random noise as masker. The highest correlations between pure-tone hearing thresholds at different frequencies and results in the SRT and JFC tests were seen at 0.5 and 1 kHz.

Self-assessed hearing problems in Sweden: a demographic study.
- 1999

Ingår i: Audiology : official organ of the International Society of Audiology. - : Informa UK Limited. - 0020-6091. ; 38:6, s. 328-34

Tidskriftsartikel (refereegranskat)abstract
- A study of self-assessed hearing problems was performed comprising 48,680 Swedish inhabitants aged 16-84 years. The participants of the survey responded to personal interviews during the period 1986-1993. One of the questions in the interview concerned difficulties of hearing in background noise. The total prevalence of the reported hearing problems was 10.7 per cent, varying from 2.4 per cent in the youngest age group to 30 per cent in the oldest. Men reported difficulties in hearing more often than women, except in the youngest age group. Hearing problems were more often reported by manual workers, unemployed and by those who had taken early retirement, than by non-manual employees and the self-employed. Regional differences regarding hearing problems were observed. The prevalence of self-reported problems was lowest in metropolitan Stockholm (7.9 per cent) and increased in the following order: other major cities (9.4 per cent), other cities (10.5 per cent), small population centres (12.5 per cent), agricultural areas (13.5 per cent) and sparsely populated forest areas (15 per cent). In summary, a number of factors related to ageing, socioeconomic status and domicile were related to self-assessed difficulties hearing a conversation. These factors obviously include determinants such as genetics, health status, gender-related differences, exposure to noise and possible conditioning effects of low-level noise exposure.

Electrocochleographic signal analysis : condensation and rarefaction click stimulation contributes to diagnosis in Menière's disorder
- 1998
-
Ingår i: Audiology. - 0020-6091. ; 37:4, s. 198-206
-
Tidskriftsartikel (refereegranskat)abstract
- Thirty patients with Menière's disorder, 11 patients with cochlear hearing loss of other aetiologies and 10 normally-hearing subjects, were investigated using transtympanic electrocochleography (TT ECochG). Alternating polarity clicks, condensation and rarefaction clicks and long tone-bursts of 1 kHz were used for stimulation. The latencies of the AP responses to click stimulation were evaluated. It was found that the latency differences between the condensation and rarefaction click-evoked responses were significantly larger in patients with Menière's disorder as compared to normal subjects and to patients with other cochlear hearing losses. It was found that the sensitivity of TT ECochG, obtained by using measurements of SP-AP ratios and the SP amplitude at 1 kHz burst stimulation, increased from 83 per cent to 87 per cent by addition of the con-rar shift measurement. The specificity of TT ECochG obtained by this combination of variables was 100 per cent in our material. The results of the study indicate that the latency shift found in responses evoked by clicks of opposite polarities in TT ECochG, can be a useful parameter in the detection of suspected endolymphatic hydrops.
