    <subfield code="a">&lt;p&gt;Objective: This study aimed to measure noise levels in hyperbaricoxygen therapy (HBOT) centers across T&amp;uuml;rkiye and to evaluate their potentialimpact on the hearing thresholds of hyperbaric chamber operators.Material andMethods: Between November-December 2021, sound intensity measurementswere conducted in 41 HBOT centers. Noise levels were recorded during the 4 op-erational phases using a calibrated sound level meter. Audiometric data from 28eligible operators were retrospectively analyzed. Hearing thresholds were cor-rected for age and sex according to the European norm International Standart ofOrganization 7029:2017 standard to isolate occupational effects. Results: Themaximum equivalent continuous sound level [Leq decibel (dB) (A)] was recordedas 81.9 dB(A), and the highest peak noise level [Lpeak dB(C)] was recorded as114.5 dB(C). In 63.4% of the centers, the 70 dB(A) limit was exceeded during thetreatment depth when the ventilation was on. A statistically significant hearingthreshold shift at 4,000 Hz was observed in the right ear (p=0.039). No operatormet the clinical criteria for noise-induced hearing loss (NIHL); however, the find-ings were suggestive of early cochlear involvement. Conclusion: Although noclinical NIHL was detected among the hyperbaric chamber operators, the signif-icant threshold shift at 4,000 Hz, the frequency often first affected by noise ex-posure, indicates the early auditory effects of occupational noise exposure. Incenters where noise levels exceed 70 dB(A), regular noise monitoring, routineaudiometric evaluations, the use of hearing protection, and the implementation ofengineering controls are recommended. These findings highlight the need for up-dated national regulations specifically tailored to HBOT centers.&lt;/p&gt;</subfield>
