AB  - The aim of the study was to develop Macedonian monosyllabic and disyllabic tests for speech audiometry, to record the
speech materials, and to conduct clinical validation of the tests. The following criteria were applied: word familiarity,
phonetic balance, and homogeneity of audibility. Clinical validation was conducted on a sample of 30 normal hearing
subjects, aged 18 to 30 years. We developed four open-set tests for speech threshold and suprathreshold testing in quiet.
The tests contain two word lists with 50 monosyllabic words and two word lists with 36 disyllabic words. Each word was
introduced by a carrier phrase. Psychometric function slope from 20% to 80% correct recognition for all words was 5%/
dB. The difference between the presentation levels at which the subjects repeated all the words was ≤ 4 dB. Developed
phonetically balanced word lists have relatively steep psychometric function slope and they are homogeneous in terms of
the audibility

AB  - Introduction: Otoacoustic emissions are sounds that result from energy generated in the cochlea. The otoacoustic emissions test helps to confirm outer hair cell function.
Aim: The objective of the study was to evaluate the expression of distortion product otoacoustic emissions in children with suspected hearing loss.
Method: This retrospective study included 115 children, 65 males (56.5%) and 50 females (43.5%), aged 0 to 14 years (mean age of 6.9±3.5 years), examined during the period from January 2017 to March 2021. The audiological assessment included Distortion product otoacoustic emissions test, tympanometry, and pure-tone audiometry in children older than 4 years.
Distortion product otoacoustic emissions were recorded in the form of DP- gram elicited by two primary tone stimuli L1=65 dB SPL and L2=55 dB SPL.
Levels of the 2f1-f2 distortion product otoacoustic emissions were registered at frequencies from 1000 Hz to 8000 Hz at four points per octave. For statistical data analysis we used Chi-square test with level of significance p<.05.
Results: From the total of 81 children with tonal audiogram, 13 children (16%) had sensorineural hearing loss with mean distortion product otoacoustic emissions amplitude -7.4 dB SPL, and 68 children (84%) had normal hearing with mean DPOAE amplitude 9.9 dB SPL. In children without tonal audiogram, distortion product otoacoustic emissions were present in 23 children (67.6%) at control examination after absence during middle ear pathology and 9 children (26.5%) at first examination. Otoacoustic emissions were absent in 2 children (5.9%) without middle ear pathology. They were mostly absent at frequency of 4000 Hz (p=.036). 
Conclusion: The otoacoustic emissions test is good cross-check for pure- tone audiometry. In children with sensorineural hearing loss, the otoacoustic emissions are absent in the range of hearing loss. In young children not cooperative for pure-tone audiometry, expression of otoacoustic emissions after previous absence during middle ear pathology would indicate that there is no coexistent sensorineural hearing loss.
