Noise in the workplace and audiometric examinations in workers of a ceramic factory.

732 workers from several loudest production departments in a pottery plant were examined. The noise level measurements were carried out at a regular course of work. Auditory sensitivity threshold was determined via air conduction, at frequencies of 250, 500, 1000, 2000, 4000 and 8000 Hz. Functioning of the organ of hearing under conditions of noise at the workplace was analysed. The influence of several noise levels--up to 85 dB/A/ and higher, and the relation between the length of service and hearing sensitivity threshold were investigated. The largest exposures were recorded in the batching and milling plant, sorting and kilns departments.

[Effectiveness of ear protective devices].

Efficiency of 9 types of hearing protectors was investigated. A subjective method of an absolute hearing threshold shift in free sound field in 20 well-hearing-persons was applied. The results obtained are presented in figures. It was found that the maximum efficiency of most hearing protectors usually fell toon the frequency of 4000 Hz and amounted to 20--41 dB. The minimum efficiency usually fell to the frequency of 125 Hz and amounted to 8--21 dB. Attenuation efficiency of broad-band noise was 18-40 dB and approximated the maximum efficiency of pure sounds, sometimes even surpassing it. The results of determinations differed from the values given by manufacturers, which accounts for the need of undertaking such investigations.

[Nasal and pharyngeal mucous membrane in workers of artistic weaving plants].

68 persons employed at the production of fabrics from wool and flax, have been subjected to otolaryngological examinations. Chronic atrophic catarrh of mucous membrane of nose and pharynx was found in all 8 persons employed in tapestry weaving mill and in 44 among 60 employees of a weaving mill operated manually. Atrophic changes occurred most frequently both in the nose and the pharynx, less frequently only in the nose, and the least frequently only in the pharynx. Chronic atrophic catarrh of upper respiratory tract mucous membrane was found to be more frequent among those with the length of employment above 5 years than those with shorter employment, though this difference was not statistically significant. No correlation was found between the occurrence of chronic catarrh of upper respiratory tract and hearing damage.
