Abstract: The results of examination of 11 patients aged 18 to 30 years with
acute sensorineural hearing loss are presented. The cause of acute sensorineural
hearing loss of these patients was the irrational use of portable audio devices. All
patients have gone through a comprehensive clinical and audiological examination. In
4 (36,4%) patients had a diagnosis of "Bilateral acute sensorineural hearing loss" and
7(63,6%) –"Unilateral acute sensorineural hearing loss". According to the results of
this study, people using headphones to listen to music loudly are at risk for
developing sensorineural hearing loss at a young age.
Keywords: sensorineural hearing loss, portable audio devices, headphones,
mobile phone.
Introduction. One of the common causes of sensorineural hearing loss
(SNHL) is the effect of high-intensity sounds on the auditory analyzer. According to
World Health Organization (WHO), 1.1 billion young people (at the age of between

12 and 35) are at risk of hearing loss as a result of exposure to noise in places of
recreation and entertainment.
SNHL can be formed by single or continuous exposure to high-intensity
sounds [1, 5].
Portable audio devices are now widely used, especially among young people
and children. This fact is widespread in many countries of the world. The literature
notes the highest risk of SNHL development in people who use headphones for three
or more hours a day [2].
The above makes it relevant to study it in detail as a significant factor in the
emergence of persistent acute SNHL.
Purpose. To study the clinical and audiological manifestations of acute SNHL
arising from the irrational use of portable audio devices.
Material and methods. The results of examination of 11 patients (the main
group) are presented. They pointed to the causal factor of the sudden onset of hearing
impairment with a sharp one-time short-term increase in the volume of sound in the
headphones, as a result of incorrect handling of the volume control function of the
mobile phone when listening to music. The latter in all patients at the time of
ascertaining acute acoustic trauma was at the maximum value of the volume level.
The age of patients varied from 18 to 30 years old, the average age was 20.2 ± 1.7
years old. Males accounted for 54.5% and females 45.5%. In the presence of past ear
diseases or their detection at the time of examination, patients were not included to
the study. The control group consisted of 11 healthy individuals.
All patients have gone through a comprehensive clinical and audiological
examination. General otorhinolaryngological examination included rhinoscopy,
pharyngoscopy, indirect laryngoscopy, otoscopy. The study of the hearing organ

included: the study of complaints, history of disease and life, acoumetry, pure tone
audiometry, audiometry in the extended frequency range of air conduction (in the
range of 10000-16000 Hz), SISI-test, tympanometry, registration of transient evoked
otoacoustic emissions – TEOAE.
Measurement of the output sound levels at the headphones was carried out
using the device "artificial ear" type 4152 and devices for studying the sound level
type 2235 (Brüel&Kjaer, Denmark).
The diagnosis of SNHL followed the International Statistical Classification of
Diseases and Health Problems of the tenth revision (ICD-10). The international
classification of hearing impairment was used to assess the degree of hearing loss
(WHO, 1997).
Calculated the value of the criterion of reliability of differences (p) was tested
using Student's t-test.
Results and discussion. The study was performed at the ENT Department of
the Tashkent Institute of Postgraduate Medical Education for the period from 2008 to
2018. Of the total number of patients, 82% used intra-channel vacuum headphones,
the remaining 18% – overhead headphones.
In 4 (36,4%) patients had a diagnosis of "Bilateral acute sensorineural hearing
loss" (Н90.3 according to ICD-10) and 7 (63,6%) – "Unilateral acute sensorineural
hearing loss" (Н90.4 by ICD-10). The predominance of unilateral hearing loss is due
to the fact that most patients indicated that they used portable audio devices only on
one ear. In a bilateral process, asymmetry in the degree of hearing impairment was
not observed.
63.6% of patients with hearing impairment combined with tinnitus in the
affected ear. In four cases, the noise had only a high-frequency character in the form
