Psychogenic hearing loss, formerly known as functional or non-organic hearing loss, is a classic cause of consultation in infantile audiology. Risk factors include female gender, and age 8 or 12 years. Onset is relatively sudden, without impact on schooling or voice quality. Audiometric signs comprise non-superimposable audiometric thresholds (variable audiometric results), bilaterality, flat mean audiometric curve, and discrepancy between pure-tone and speech audiometry. The child needs reassuring during audiometric examination: attention-diversion techniques may be effective. Objective audiometry allows positive diagnosis, followed by rehabilitation and psychological care.

BACKGROUND
Electrocochleography (ECochG), one of the first defined tests under auditory evoked potentials, is a total electrical response of inner and outer hair cells inside the cochlea and auditory nerve record technique to the presence of an acoustic stimulus. These records can be used in Meniere disease and auditory neuropathy spectrum disorder diagnosis, intraoperative monitoring. In addition, the presence of cochlear microphonics plays a crucial role in auditory neuropathy spectrum disorder diagnosis. In our study, healthy individuals were tested with extratimpanic electrocochleography record method via Click and LS CE-Chirp stimulus, and the results were compared to the age, sex, and noise sensitivity categories.
METHODS
This study had executed at Başkent University, Faculty of Health Sciences Audiology laboratory. The study group consisted of 42 volunteers between 18 and 40 years old. To understand the suitability of volunteers, pure tone audiometry, tympanometry, and transient otoacoustic emission tests were performed. Individuals with no hearing loss were tested with 100 dBnHL intensity level via click and LS CE-Chirp stimulus. The obtained values were statistically evaluated in the SPSS 23.0 program in accordance with the data distribution. An independent sample t-test was used for data showing normal distribution, and Mann-Whitney U test was used for data not showing normal distribution. The level (p < 0.05) was considered statistically significant for all analyses performed.
RESULTS
Cochlear microphonic amplitudes recorded with click and LS CE-Chirp stimuli were higher in males than in females (p = 0.051 and p = 0.001, respectively). When the age groups were evaluated, no difference was observed in the CM amplitudes obtained with both click and LS CE-Chirp stimuli. There was no correlation between age and CM amplitudes. Additionally, it was determined that the CM amplitudes recorded with the click stimulus in individuals with noise sensitivity were higher than those without noise sensitivity (p = 0.051).
DISCUSSION
It is thought that the ECochG amplitudes of different gender, different age, and different noise sensitivity, which are the results of our study, can be used in the diagnosis of diseases such as auditory neuropathy spectrum disorder.

BACKGROUND
There is evidence to suggest that rates of hearing loss are increasing more rapidly than the capacity of traditional audiometry resources for screening. A novel innovation in tablet, self-administered portable audiometry has been proposed as a solution to this discordance. The primary objective of this study was to validate a tablet audiometer with adult patients in a clinical setting. Secondarily, word recognition with a tablet audiometer was compared against conventional audiometry.
METHODS
Three distinct prospective adult cohorts underwent testing. In group 1 and group 2 testing with the automated tablet audiometer was compared to standard sound booth audiometry. In Group 1, participants' pure tone thresholds were measured with an automated tablet audiometer in a quiet clinic exam room. In Group 2, participants completed monosyllabic word recognition testing using the NU-6 word lists. In Group 3, internal reliability was tested by having participants perform two automated tablet audiometric evaluation in sequence.
RESULTS
Group 1 included 40 patients mean age was 54.7 ± 18.4 years old and 60% female; Group 2 included 44 participants mean age was 55.2 ± 14.8 years old and 68.2% female; Group 3 included 40 participants with mean age of 39.4 + 15.9 years old and 60.5% female. In Group 1, compared to standard audiometry, 95.7% (95% CI: 92.6-98.9%) of thresholds were within 10 dB. In Group 2, comparing word recognition results, 96.2% (95% CI: 89.5-98.7%) were clinically equivalent and within a critical difference range. In Group 3, One-way Intraclass Correlation for agreement for the both left- and right-ear pure tone average was 0.98. The mean difference between repeat assessments was 0 (SD = 2.1) in the left ear, and 0.1 (SD = 1.1) in the right ear.
CONCLUSION
Puretone audiometry and word recognition testing appears valid when performed by non-healthcare experts using a tablet audiometer outside a sound booth in a quiet environment.

Objective The tests of three types of auditory evoked potentials (AEPs) were performed on normal young adults, to understand the frequency characteristics of different testing methods and the relationship between response threshold and pure tone audiometry threshold of different methods, and to discuss the forensic value of 3 types of AEPs to evaluate hearing function. Methods Twenty normal young adults were selected, their standard pure tone audiometry threshold, short-term pure tone audiometry threshold and the response threshold of 3 types of AEPs (tone burst-auditory brainstem response, 40 Hz auditory event-related potential and slow vertex response) at 0.5 kHz, 1.0 kHz, 2.0 kHz and 4.0 kHz were recorded. The relationship between the response threshold and standard pure tone audiometry threshold, short-term pure tone audiometry threshold of 3 types of AEPs at different frequencies as well as the differences between different types of AEPs were analyzed. Results The short-term pure tone audiometry threshold was higher than the standard pure tone audiometry threshold at each frequency. The response threshold and standard pure tone audiometry threshold of the 3 types of AEPs all had a certain correlation, and the response threshold of the 3 types of AEPs was higher than short-term pure tone audiometry threshold and standard pure tone audiometry threshold at each frequency. The differences in the differences between the response threshold and standard pure tone audiometry threshold of the 3 types of AEPs at different frequencies had statistical significance. Linear regression mathematical models were established to infer the standard pure tone audiometry threshold (hearing level) from response threshold (sound pressure level) of 3 types of AEPs of normal young adults. Conclusion When using response threshold of different types of AEPs to estimate pure tone audiometry threshold, conversion and correction are needed. Combined use of different types of AEPs could improve the accuracy of hearing function evaluation.

Observational Study
PURPOSE
To compare the air-conduction hearing thresholds obtained with different acoustic transducers and verify the users' preferences regarding them.
METHODS
This is a cross-sectional, analytical, observational study with 26 participants aged 18 to 30 years, with normal hearing and no history of exposure to high sound pressure levels or complaints of tinnitus at the time of the assessment. We surveyed their medical history and performed meatoscopy, pure-tone threshold audiometry, speech audiometry, and acoustic immittance. The auditory thresholds were surveyed twice, each time with a different type of acoustic transducer: insert (E-A-RTONE) and circumaural earphones (HDA200). The assessments were performed in a random order, with 5-minute intervals. In the end, we asked the participants which earphones they found more comfortable in the tests. The data were submitted to nonparametric statistical analysis.
RESULTS
Assessing the medians in the auditory threshold survey, the circumaural earphones obtained better results at 250, 500, 2000, and 6000 Hz, while the insert earphones were better at 3000 and 4000 Hz; there were no statistical differences at 1000 and 8000 Hz. The circumaural was elected the most comfortable earphone.
CONCLUSION
The circumaural earphones had better auditory thresholds at 250, 500, 2000, and 6000 Hz than the insert earphones and were reported by the patients as the most comfortable type of transducer.

Review
The tuning fork tests have been under attack since their first use in clinical examination. However, the tuning fork is small and fits into every white coat, and tuning fork tests for hearing are easy, accurate and inexpensive. They should be used in patients with an acute unilateral hearing loss if an electric audiometer is not available. After more than 100 years, the tuning fork is not obsolete; tuning fork tests are very useful if used correctly and for the appropriate indication.

OBJECTIVE
To investigate the sensitivity and specificity in an automatic computer-controlled audiometric set-up, used for screening purposes.
DESIGN
Comparison between standardized audiometry and automated audiometry performed in the same participants.
STUDY SAMPLE
In total, 100 participants (51 females and 49 males) were recruited to take part of this study the same day they visited the hearing clinic for clinical audiometry. Ages varied between 18 and 84 years (mean 45.9 in females, 52.3 in males).
RESULTS
The participants were divided into groups, dependent of type of hearing. A total of 23 had normal hearing, 40 had sensorineural hearing loss, 19 had conductive hearing loss and 18 showed asymmetric hearing loss. The sensitivity for the automated audiometry was 86%-100% and the specificity 56%-100%. The group with conductive hearing loss showed the poorest sensitivity (86 %) and specificity (56 %). The group with sensorineural hearing loss showed the smallest variation in difference between the two methods.
CONCLUSIONS
The results show that automated audiometry is a method suitable to screen for hearing loss. Screening levels need to be selected with respect to cause of screening and environmental factors. For patients with asymmetric hearing thresholds it is necessary to consider the effect of transcranial routing of signals.

To explore the value and influencing factors of behavioral audiometry in subjective hearing assessment of children. The results of behavioral audiometry(visual reinforcement audiometry or play audiometry) of 1944 children(3888 ears) in the outpatient department from January 2012 to December 2015 were retrospectively analyzed. The subjective performance(" good ", "moderate", "poor", " unfinished ") was compared according to age and hearing level. SPSS 27.0 software was used for statistical analysis. The subjective performance of children was "good" in 2791 ears(71.8%), "moderate" in 411 ears(10.6%), "poor" in 309 ears(7.9%) and " unfinished " in 377 ears(9.7%). In visual reinforcement audiometry, the proportion of children who subjectively performed as "good" gradually increased with age, reaching the peak at 2 years old, and decreased with age after 2 years old. In play audiometry, the proportion of children who subjectively performed as "good" gradually increased with age, peaking at 4-5 years of age. The children who did not finish the test were mainly 1-3 years old. The reasons included uncooperation for 148 ears, crying for 95 ears, refusing to wear headphones for 57 ears, fatigue for 42 ears, lack of interest for 20 ears, not understanding for 14 ears, and distraction for 1 ear. Behavioral audiometry was helpful to assess children's subjective hearing, and children's subjective performance was good. In clinical work, more novel and attractive test materials and methods should be adopted or developed according to the physical and mental characteristics of young children.

Statistical approaches that could be used as standardized methodology for evaluating reliability and validity of data obtained using remote audiometry are proposed. Using data from the Nurses' Health Study II (n = 31), the approaches to evaluate the reliability and validity of hearing threshold measurements obtained by a self-administered iPhone-based hearing assessment application (Decibel Therapeutics, Inc., Boston, MA) compared with measurements obtained by clinical (soundbooth) audiometry are described. These approaches use mixed-effects models to account for multilevel correlations, intraclass correlation coefficients (ICCs) of single and averaged measurements, and regression techniques with the generalized estimating equations (GEEs) to account for between-ear correlations. Threshold measurements obtained using the iPhone application were moderately reliable. The reliability was improved substantially by averaging repeated measurements; good reliability was achieved by averaging three repeated measurements. In the linear regression analyses that assessed validity, the range of intercepts (2.3-8.4) and range of slopes (0.4-0.7) indicated that the measurements from the application were likely biased from those obtained by clinical audiometry. When evaluating alternative hearing assessment tools, it is recommended to assess reliability through mixed-effects models and use ICCs to determine the number of repeated assessments needed to achieve satisfactory reliability. When evaluating validity, GEE methods are recommended to estimate regression coefficients.
