Loud Music

Introduction. For human ear, noise represents every undesirable and valueless sound. In disco clubs, as in some other places with loud music mostly attended by young people, the level of noise sometimes attains over 100 dB. As reported by numerous studies, a high noise level could induce subjective difficulties (ear buzzing, audition loss, vertigo and palpitations, anxiety, high blood pressure, decreased concentration, lowered memory storing). Objective. Assessment of subjective difficulties occurring in young people when staying in places with a high noise level (cafes, disco clubs, rock concerts), which can produce health problems, due to loud music, in association with demographic data, addictions and personal life style data. One of the goals is to find factors leading to subjective difficulties, which would be objectively studied in the second stage of the research and marked as early predictors of possible health problems. Methods. The study was conducted among 780 students of the Higher Healthcare School of Professional Studied in Belgrade. We used a questionnaire with 20 questions, divided into four categories: demographic data, case-history data, subjective problems and addictions of the subjects. In the statistical data processing we used the methods of descriptive and exploratory analysis, chi-square tests, correlation tests and Mantel-Haenszel odds ratio. Results. After listening loud music, 54.0% of examined subjects felt ear buzzing, and 4.6% had hearing damage. The habit of visiting places with loud music, mostly once a week in duration of 2-3 hours per visit had 80.4% of subjects. The presence of subjective complaints after listening of loud music was in association with loud music listening and disco clubs visits. The major reasons of the present subjective difficulties could be predicated by listening of loud music and club visits (r=0.918 and r=0.857). A relative risk for subjective difficulties presentation was 1.599. Conclusion. According to the results of our study, over half of children develop loud music-induced subjective problems involving ear buzzing and occasionally hearing loss.

Seismic Records

One of the most promising methods of identification or cancellation of multiple reflections on seismic records involves the calculation of synthetic records with all primaries and multiples, and the matching of the synthetic record with the field record. Such matching suffers today from the lack of precise information about the velocities and densities of the formations, dips of beds nonvertical transmission, etc. One possibility of improving this match involves the use of the earth itself as the “synthetic record computer.” In this process, the upcoming (or downgoing) primary signals are fed back into the earth with a vibrator in proper amplitude and phase to create a synthetic record of multiples only, which should match the multiples on the field record. Of course, only those multiple reflections which include a downward reflection from beds above the primary signal detectors will be included in the synthetic record of multiples only. The paper reports two experimental programs. One was carried out on an analog network to simulate the near‐surface and deeper formations, with means to feed back the upcoming signals in proper timing and polarity to cancel the multiples. These experiments indicated the theoretical workability of the process. The second program of experiments involved the use of a vertical spread to detect the upcoming and downgoing signals, and the use of a hydraulic vibrator to impress those signals back into the earth. These experiments were not conclusive because of insufficient power in the vibrator and high noise level. However, they indicated possible ways in which these limitations might be reduced, and the method applied to routine field operations.

Internet of Things is a medium by which we can control our appliances from anywhere in the world. In Industry many times accidents happened due to negligence of workers and there are some risky areas in Industry where workers not able to go and work. Voice-controlled Industrial parameters monitoring and controlling system are used in the risky areas of Industries usually in power plants where there are high noise level and pollution to avoid accidents. Here an induction motor speed, temperature, pressure, etc are monitored and controlled to avoid damage to the motor. These all the parameters are going to monitor and controlled automatically. In this paper, Google-Assistant and Adafruit IO server are used for monitoring and controlling. By using this system the workers can monitor and control Industrial appliances and problems occur in Industries where workers not able to go and work are overcome.

<p class="apa">Scholarly work and research are globally known as stressful and challenging. Teachers may develop different psychological health problems once they are exposed to workplace stressors. Considering it as a serious issue of education sector, this study has examined the linkages between prevalent workplace stressors and psychological health problems in Pakistan’s academia. A cross-section quantitative research design was adopted, whereas data was collected by self-administered questionnaire from a sample of 1189 teachers working within 12 universities of Pakistan. Descriptive statistics were used for analysis of demographic data; Chi-square tests were performed to compare psychological health problems with socio-demographic characteristics, whereas Multivariate Logistic Regression Analysis was run to know the relationship between prevalent work stressors and psychological health problems. Results show that the majority of respondents were male (63.8%), unmarried (58.5%), 25 to 40 years old (78.5%) and working as Lecturers or Assistant Professors (77%), thus their average job experience was 05 to 10 years. Psychological health problems were prevailing more among male, unmarried, less experienced and junior teachers. Such socio-demographic characteristics were potential risk factors for psychological health problems. Furthermore, respondents exposed to work stressors like workload, interpersonal and emotional demands were more likely to develop psychological health problems. Findings of the current study will develop awareness among teachers concerning work stress and psychological health. Such findings can be utilized by policy makers of Pakistan for devising policies about occupational health &amp; safety of teachers.<strong> </strong>The prevalence of psychological health problems in academia of Pakistan is a recognized workplace issue. Therefore, it needs immediate corrective measures at individual and institutional levels.</p>

The study was carried out to ascertain the level of noise pollution at different locations in Tangail municipal area. For this purpose noise levels were measured at different locations at different periods of the day. At all the locations the level of noise were found to be higher than the acceptable level. The intensity of noise was found lower with increasing distance from the road side. The noise level on the main road near hospital, shopping center and bazars was above the standard level recommended by MoEF. From the survey motor vehicles were found as the main cause of high noise level. The most common problems with high noise level were found to increased heart beat, drowsiness, headache and hearing impairment. DOI: http://dx.doi.org/10.3329/bjsr.v26i1-2.20228 Bangladesh J. Sci.
