Sound Pressure Levels

Differences in real ear sound pressure levels (SPLs) with three portable stereo system (PSS) earphones (supraaural [Sony Model MDR-44], semiaural [Sony Model MDR-A15L], and insert [Sony Model MDR-E225]) were investigated. Twelve adult men served as subjects. Frequency response, high frequency average (HFA) output, peak output, peak output frequency, and overall RMS output for each PSS earphone were obtained with a probe tube microphone system (Fonix 6500 Hearing Aid Test System). Results indicated a significant difference in mean RMS outputs with nonsignificant differences in mean HFA outputs, peak outputs, and peak output frequencies among PSS earphones. Differences in mean overall RMS outputs were attributed to differences in low-frequency effects that were observed among the frequency responses of the three PSS earphones. It is suggested that one cannot assume equivalent real ear SPLs, with equivalent inputs, among different styles of PSS earphones.

Christian-Jewish Dialogue in the Land of Sick Imagination. On the Margins of Waldemar Chrostowski’s Book Kościół, Żydzi, Polska

The article is a polemic with the pessimistic assessment of the current state of the Christian-Jewish dialog presented by Waldemar Chrostowski in his recent book Kościół, Żydzi, Polska [The Church, Jews, Poland]. The author criticizes Rev. Chrostowski for defining the Christian-Jewish and Polish-Jewish relations in terms of strict opposition and unavoidable conflict of interests, and for putting all blame on Jews, while absolving Christians from all their past and present sins which contributed to the tensions between the two communities.

The features of production factors established at the main workplaces of shoe production are considered. The materials on the results of the study of the functional state of the central nervous system of women workers of shoe production in the dynamics of the working day are presented. The level of functional state of the central nervous system was determined by the speed of visual and auditory-motor reactions, installed using the universal device chronoreflexometer. It was revealed that in the body of workers of shoe production there is an early development of inhibitory processes in the central nervous system, which is expressed in an increase in the number of errors when performing tasks on proofreading tables. It was found that the most pronounced shift s in auditory-motor responses were observed in professional groups, where higher levels of noise were registered in the workplace. The correlation analysis showed a close direct relationship between the growth of mistakes made in the market and the decrease in production. An increase in the time spent on the task indicates the occurrence and growth of production fatigue.Funding. The study had no funding.Conflict of interests.

Objective. To provide a basis for the effective prevention of the same type of poisoning events through analyzing the causes of an occupational acute simple asphyxiating gas poisoning incident.Method. Descriptive epidemiological method was used to investigate the related personnel of the poisoning incident, detect poisonous and harmful gases in the air of the scene, and collect and analyze the clinical data of patients.Result. The poisoning incident led to 1 death and 2 poisoning. All of them were male. The dead patient was 38 years old, and two injured patients were 37 and 31 years old, respectively. The day after the accident, the contents of phenol, toluene, hydrochloric acid and oxygen were determined in the reactor where the accident occurred. The results showed that the maximum concentration of phenol, toluene and hydrochloric acid (CM) was 0/m3 , which did not exceed the occupational exposure limit of harmful factors in the workplace stipulated by GBZ2.1–2007. Also, the oxygen content was 10.0%, which was lower than the oxygen content in normal air.Conclusion. This is an acute simple asphyxiating gas poisoning incident caused by the employing unit managers and operators’ weak awareness of occupational hygiene and safe operation. The employing unit managers and operators should strengthen occupational safety training, strictly implement the occupational health management system, and prevent such incidents.Funding. Th e study had no funding.Conflict of interests. The authors declare no conflict of interests.
