When a bilateral evaluation is conducted with the integrated speech protocol described in Punch and Rakerd (2019), testing for the first ear concludes with a measurement of the uncomfortable loudness ...
Across 32 test runs, the left and right ear MCLs were established for 16 young adult listeners with normal hearing (five women, 11 men). The MCL assessed on each test run was measured twice. The first...
The difference between the MCL means measured on the pretest (37.7 dB) and the posttest (38.5 dB) was less than 1 dB, and it did not approach statistical significance,...
There was no evidence that UCL testing done in one ear on a bilateral speech test will have carryover effects that bias the subsequent measurement of a listener's MCL in the other ear. The results, th...
The purpose of this study was to verify the accuracy of the web-based audiometer HEARZAP in determining hearing thresholds for both air and bone conduction....
Using a cross-sectional validation design, the web-based audiometer was compared to a gold standard audiometer. Participants in the study totaled 50 (100 ears), of which 25 (50 ears) had normal hearin...
For air conduction thresholds and bone conduction thresholds, respectively, the mean discrepancies between the web-based audiometer and the gold standard audiometer were 1.22 dB HL (SD = 4.61) and 0.8...
The web-based audiometry version of HEARZAP produced precise findings for hearing thresholds that were comparable to those obtained from an established gold standard audiometer. HEARZAP, has the poten...
There is an increasing need to administer hearing tests outside of sound-attenuating rooms. Maximum permissible ambient noise levels (MPANLs) from published in standards (Occupational Health and Safet...
In Part I MPANLs provided by ANSI and OSHA standards are extended to account for the greater attenuation provided by circumaural earphones. Rules ("alerts") were developed taking into account the list...
In Part I MPANLs two standards were modified for circumaural earphones by adding the additional attenuation provided by three circumaural earphones (relative to supra-aural earphones). A set of rules ...
Part I: The modified MPANLs provide more relevant determinations of the potential effects of ambient noise on pure-tone thresholds than the values in the standards. Part II: Distracting noise affects ...
This study aimed to determine hearing thresholds in an otologically normal population without occupational noise exposure aged 18 to 64 years using extended high-frequency audiometry (EHFA)....
Individuals from the general population who have never had hearing problems and whose job was not associated with noise exposure were included in the study and classified by age into 5 categories: 18-...
Here, we established hearing thresholds in an otologically healthy population within the extended high-frequency (EHF) range (9-16 kHz). We found the EHFA to be a highly sensitive method for early det...
Our results can help improve the knowledge of EHF hearing thresholds for individual sexes and age groups. So far, the standard 7029:2017 is not binding and, moreover, it only reaches up to the frequen...
One of the main treatment goals in cochlear implant (CI) patients is to improve speech perception. One of the target parameters is speech intelligibility in quiet. However, treatment results show a hi...
Audiometric findings of the CI follow-up of 28 adult patients after 6 months of CI experience were evaluated. These were related to the preoperative audiometric examination and evaluated with respect ...
Inclusion of postoperative categorical loudness scaling and hearing loss for Freiburg numbers in the model explained 55% of the variability in fitting outcomes with respect to monosyllabic comprehensi...
The results of this study suggest that much of the cause of variability in fitting outcomes can be captured by systematic postoperative audiometric checks. Immediate conclusions for CI system adjustme...
To evaluate two user-operated audiometry methods, the AMTASTM PC-based audiometry and a low-cost smartphone audiometry research application (R-App)....
A repeated-measures within-subject study design was used to compare both user-operated methods to traditional manual audiometry and to evaluate test-retest reliability of each method....
58 subjects were recruited in the study of which 83 ears had normal hearing thresholds and 33 ears had hearing loss (pure-tone average > 25 dB HL). Average age of participants was 44.8 years, with an ...
Standard deviation of absolute differences ranged between 3.9-6.9 dB on AMTASTM and 4.5-6.8 dB on the R-App. The highest variability was found at the 8000 Hz frequency (R-App and AMTASTM test) and 300...
Accuracy of AMTASTM and the R-App was within acceptable limits for audiometry and comparable to traditional manual audiometry on all tested frequencies (250-8000 Hz). Evaluation of test-retest reliabi...
There are studies on the perinatal outcomes of COVID-19, but the audiometric effects of the maternal immune system against COVID-19 in the newborn are not clear. In this study, we aimed to investigate...
This retrospective, single-center cohort study was conducted with 65 polymerase chain reaction (PCR) positive pregnant women and newborns and 66 normal pregnant women and newborns who were admitted be...
A total of 131 patients were enrolled in the study. The number of normal pregnant women was 66 (50.4%) and the number of pregnant women who had COVID-19 disease was 65 (49.6%). In general, gestational...
Although the negative effects of COVID-19 on pregnancy outcomes are rare, it was determined that there was no increased audiological risk factor, and the most important predictor of COVID-19 was lymph...
Correct execution of hearing tests is essential for audiologic diagnostics and selection of treatment by the ENT physician. Especially in the case of pure-tone and speech audiometry, incorrectly perfo...
User-operated audiometry faces multiple barriers. One of these is the concern of audiologists that patients (non-experts) placing headphones by themselves results in invalid hearing thresholds due to ...
Comparative study. Participants took the AMTAS pure-tone air-conduction audiometry under two different conditions, expert and non-expert circumaural headphone placement for five frequencies within the...
Thirty participants (mean age 67.5 years)....
No statistically significant mean differences in hearing thresholds between the expert and non-expert conditions were found. The mean system usability scale score was 84.5. Handling the headphones was...
The conclusion of the study is that non-experts can be trusted to properly equip a pair of circumaural audiometry headphones for the correct conduction of pure-tone audiometry with only a few digital ...
The study aimed to analyse the hearing levels of patients with gout using extended high frequencies (EHFs) audiometry. Thus, we aimed to reveal the early detectability of potential hearing losses....
Comparative cross-sectional study....
A single centre patient was diagnosed with gout disease....
Two groups consisted of 32 patients with gout and 32 healthy volunteers....
The primary outcome was hearing thresholds in pure tone (PT) audiometry and EHFs audiometry. Also, the association between audiometric results and haematological and biochemical parameters were evalua...
There was no significant difference between groups in terms of mean hearing thresholds in PT audiometry. But, at all frequencies above 4000 Hz (4000-18 000 Hz), the hearing thresholds were significant...
To our knowledge, this is the first study in the literature demonstrating the high frequency of hearing loss in patients with gout using EHFs audiometry. We consider that using EHFs audiometry should ...
