“…Automation of articulation tests [28] enabled a significant reduction in their resource intensity. Analysis of the features of the hearing system, presented in the form of a kind of spectral analysis system [29], made it possible to clarify the model of the middle ear [30]. In the development of measures aimed at correcting the acoustic characteristics of the room, the results of analytical [31] and experimental [32] studies of the acoustic field near reflecting surfaces are very useful.…”

The scores of speech intelligibility, obtained using objective and subjective methods for three university lecture rooms of the small, medium, and large sizes with different degrees of filling, were presented. The problem of achieving high speech intelligibility is relevant for both students and university administration, and for architects designing or reconstructing lecture rooms. Speech intelligibility was assessed using binaural room impulse responses which applied an artificial head and non-professional quality audio equipment for measuring. The Speech Transmission Index was an objective measure of speech intelligibility, while the subjective evaluation of speech intelligibility was carried out using the articulation method. Comparative analysis of the effectiveness of parameters of impulse response as a measure of speech intelligibility showed that Early Decay Time exceeded the score of the T30 reverberation time but was ineffective in a small lecture room. The C50 clarity index for all the considered lecture rooms was the most informative. Several patterns determined by the influence of early sound reflections on speech intelligibility were detected. Specifically, it was shown that an increase in the ratio of the energy of early reflections to the energy of direct sound leads to a decrease in speech intelligibility. The exceptions are small, up to 30‒40 cm, distances from the back wall of the room, where speech intelligibility is usually slightly higher than in the middle of the room. At a distance of 0.7–1.7 m from the side walls of the room, speech intelligibility is usually worse for the ear, which is closer to the wall. The usefulness of the obtained results lies in refining the quantitative characteristics of the influence of early reflections of sound on speech intelligibility at different points of lecture rooms.

Для дослідження такого важливого діагностичного параметру, як резонансна частота слухової системи людини, була обрана електромеханічна модель середнього вуха та визначено основні її параметри, а саме: гнучкість барабанної перетинки та барабанної порожнини, акустичний імпеданс повітря в барабанній порожнині та слуховій трубі, резонансні частоти коливальної системи середнього вуха, маса слухових кісточок. Для експериментального визначення резонансних частот середнього вуха людини використано методи акустичної імпедансометрії та отоакустичної емісії, які є основними методами дослідження стану слухової системи людини та дозволяють детально оцінити суть патологічних процесів. Бібл. 10, рис. 2, табл. 1. Ключові слова-середнє вухо; слухові кісточки; резонансні частоти; формула для параметру норми середнього вуха; імпеданс; тимпанометрія; отоакустична емісія

The ear is an organ that is able to detect or recognize sound and also has a lot to play in the balance and position of the body. The ears are organs that are very vulnerable to noise. There are two common causes of hearing loss, namely decreased hearing conduction (hearing loss) and nerve hearing (sensorineural hearing loss). To prevent deafness, hearing control is necessary. Generally to test hearing function is done regularly by the ENT doctor at the hospital. This if done many times is deemed ineffective because it is time consuming and requires relatively expensive costs, therefore an early diagnosis of portable hearing loss is designed that is expected to be able to test independently independently over and over again. This tool is equipped with SD Card data storage, where the results of the data can be consulted by a doctor for further diagnosis. This tool uses an arduino uno R3 control, the frequency generator uses IC XR2206. The highest error is at the frequency of 8000 Hz which is 0.52%, but overall all systems on the device are functioning properly and the error is still within tolerance of 10%. From the results of these data, this tool can be recommended for early diagnosis of hearing function.
