Introduction: There is serious concern on noise hazard in the operating theatre, especially in the orthopaedics field that requires usage of many instruments. However, local data on this noise exposure is rather limited. This study was conducted as a pilot study to investigate the noise exposure in orthopaedics theatre in a hospital in Kuantan, Pahang in June 2011. Methods: Several different orthopaedics theatres involving procedures that use powered instruments were investigated. Time recorded noise exposures were taken using a noise dosimeter throughout the surgeries worn by the surgeons. The peak noise level and the average noise exposure within 8 hours were determined, and compared with available health guidelines, namely the Factories and Machinery (Noise Exposure) Regulations 1989. Results: Six out of seven surgeries which include interlocking nail and plating of femur, Ilizarof insertion, total knee replacement and dynamic hip screw insertion of the femoral head were found to exceed 140 dB(A) for peak sound levels. The average noise exposure within 8 hours was below 85 dB(A) in all cases. Although the average noise level did not surpass the health guidelines, the peak level exceeding 140 dB(A) still carries risk for hearing loss. Conclusions: In conclusion, healthcare personnel in operating theatre were exposed to noise hazard for certain orthopaedics surgical procedures. Hence, proper noise management should be implemented to protect them from noise-induced hearing loss while maintaining the success and efficiency of the surgeries.

The purpose of this study was to determine if noise in a high school woodworking class could contribute to the incidence of hearing loss. Students in the woodworking class served as the experimental group, and students in a technical drawing class were the control group. Four separate experiments were conducted. Experiment 1 consisted of measuring and comparing the sound levels in the woodworking and the technical drawing class environments. In Experiment 2, dosimetry samples of the students in both classrooms were collected. In Experiment 3, the temporary threshold shifts (TTSs) were determined for students in both groups by assessing hearing thresholds at the beginning and end of a single class period. The focus of Experiment 4 was to determine if a threshold shift had occurred in the hearing of the students in the woodworking class over a semester. Results of this study suggest that hazardous noise levels in the high school woodworking shop caused statistically significant TTS among the students. Relatively low noise doses were recorded, but no significant changes in hearing thresholds from the beginning to the end of the semester were noted. It was concluded that repeated noise exposure in a woodworking class may be a contributing factor to hearing loss among a student population and that a hearing conservation program should be instituted in these high school environments.

Noise-Induced Hearing Loss (NIHL) is a global issue that is caused by many factors. The purpose of this study was to survey noise level to identify NIHL and its relationship with other factors in cement plants in Vietnam. Noise level was measured at one cement plant and three cement grinding stations located in the South of Vietnam. The audiometric data of exposed workers were surveyed to determine NIHL. Finally, the relationship between NIHL and noise level in cement plants was determined. The results show that noise level in almost all processes exceeded the permissible exposure limit (PEL). In this study, 42 cases (10% of exposed workers) with occupational NIHL were found with mean age (SD) of 49 (9.0) years. All NIHL cases were found in the departments in which the noise level exceeded the PEL, which included quarry (n = 16), maintenance (n = 12), production (n = 10), co-waste processing (n = 3) and quality assurance (n = 1). There was a positive and significant correlation between the NIHL and the excessive noise exposure in the cement plants (r = 0.89, p = 0.04).

Noise exposure, hearing loss and associated otological symptoms have been studied in a group of 23 disc jockeys using a questionnaire and pure tone audiometry. The level of noise exposure in the venues where they work has also been studied using Ametek Mk-3 audio dosimeters. Three members of the study group showed clear evidence of noise-induced hearing losson audiometry, 70 per cent reported temporary threshold shift after sessions and 74 per cent reported tinnitus. Sound levels of up to 108 dB(A) were recorded in the nightclubs. The average level for a typical session was 96 dB(A) which is above the level at which the provision of ear protection is mandatory for employers in industry. It can be concluded that DJs are at substantial risk of developing noise-induced hearing loss and noise exposure in nightclubs frequently exceeds safe levels.

Hearing Assessment

Noise exposure is one of the major causes of permanent hearing loss in society. Exposure of health service staff to intense levels of noise in the workplace is a potential risk for the development of temporary and permanent hearing loss.In this prospective study, 18 members of the orthopaedic staff underwent hearing assessment by pure tone audiometry and speech discrimination prior to noise exposure at the workplace and immediately following cessation of work. The number of hours of exposure and noise levels in the workplace was also analysed.Only minimal temporary sensorineural threshold shifts were detected post-noise exposure. There was no change in speech discrimination scores and no individuals complained of tinnitus. The number of hours of exposure ranged from 1.5 to 8.5 hours (mean 5.2 hours). Recorded sound levels for instruments ranged from 119.6 dB at source to 73.1 decibels at 3 metres.Although high sound levels are recorded in the orthopaedic operating theatre, the intermittent nature exposure to the intense noise may protect staff against hearing loss, speech discrimination difficulties and tinnitus.

Jember Regency is one of the agro-industrial areas in Indonesia with a variety of activities that can produce noise including milling industry. Exposure to noise that is too strong or too long will damage the auditory nerve. The type of material being grounded determines the amount of noise produced so that the potential for hearing nerve damage also varies. This study aims to determine the level of noise produced by the milling industry and analyze the potential for hearing nerve damage in milling workers in Jember Regency. This type of research is observational analytic with cross-sectional approach. This research was conducted by measuring noise in several grinding locations in Jember that were randomly determined. Types of careful milling is grinding meat, coffee, rice, sticky rice and coconut. In addition to measuring the noise level, a short interview was also conducted with the mill workers regarding how long they worked at the mill every day. The measurement results are then analyzed descriptively and compared with standards set by the government and the Occupational Safety and Health Administration (OSHA). In this study it was found that the grinding of meat raw materials produced an average noise level of 88.5 db, coffee of 88.5 db, rice of 88.9 db, sticky rice of 87.3 db and coconut of 80.7 db. The duration of exposure to noise in milling meat, coffee, rice and sticky rice ranges from 9-12 hours a day. While the duration of noise exposure to coconut milling workers ranged from 6-9 hours. Therefore it can be concluded that milling meat, coffee, rice and sticky rice has the potential to cause hearing loss for workers. Keywords: agroindustry, hearing loss, noisy, milling

Noise and vibration can be the cause of serious disturbance and inconvenience to anyone exposed to them and in certain circumstances noise and vibration can be a serious hazard to health, causing        permanent damage to hearing system. Noise exposure levels of construction workers are difficult to determine due to the day to-day variation in occupation and shift length of each worker and the itinerant and seasonal nature of the job. Nevertheless, it is clear that the construction worker is exposed to very high sound levels for considerable lengths of time. Different types and sizes of equipment's, machineries and tools are used by construction industries. Diesel Generator for power is a very important one among the equipment used in the construction industries, used in large numbers and as clusters and also located very near to the work area. The noise level produced by these generators is much higher than the permissible limit. But the construction work group took very little effort to avoid or minimize this noise level to permissible level. Many people even though they may not need electricity for their work got in and exposed in this zone of danger. At this site eight generators have been used by various working groups. This paper assesses the potential noise impacts associated with power generators used in construction activities of the DCT project site and the effective steps to control this noise. A 12-hour noise survey was conducted to establish background noise levels in the project area. DOI: http://dx.doi.org/10.3126/ijosh.v3i2.6145

Hearing loss induced in thirty female workers because of exposure to continuous noise was studied in a plastic bag plant in Samutprakarn Province, the largest industrial zone in Thailand. The sound level in this plant was 98.5 dBA., 94.0 dBA. and 93.0 dBA. in the weaving, winding and warping sections, respectively. Results of an audiometric test showed a significant relationship between high noise level and hearing loss at frequency 4, 000 Hz. A questionnaire survey found that a relatively high number of workers had various symptoms such as: 76.7% general fatigue, 70% headache, 63.3% ear distension and 56.7% vertigo. Concerning the usage of ear protective devices, it was found that 80% of the workers have never used such devices, 16.7% occasionally used them, and 3.3% have always used cotton wool to reduce the high noise level. Their reasons for non-use of ear protective devices were 1) not provided by the employer (86.7%), 2) not necessary (83.3%), 3) accustomed to the noise (63.3%), 4) nobody uses (56.7%), and 5) no loud noise (16.7%). These results point to the need for improving the work conditions and welfare services of the workers at this plant. Also, hearing conservation programmes can be instituted in developing countries through cooperation among the safety inspectorate, the employer and the workers.

Noise exposure can leads to health effect such as Noise Induced Hearing Loss (NIHL) and tinnitus. Besides workplace, noise can be obtained from using earphones. The aim of this study was to analyze the effect of using hearing protection and earphone on NIHL and tinnitus in workers at PT DPS machine workshop. This was a cross sectional with observational analytic study design. This study was conducted in 37 workers at PT DPS machine workshop exposed to noise by using simple random sampling. Results showed that noise level in workplace was 88,57 dBA (8 hours TWA) which exceed TLV 85 dBA. Prevalence of NIHL and tinnitus in workplace was respectively 21.6% and 54%. NIHL affected by using hearing protection and earphone (MLR, p < 0.01; p < 0.05 respectively) and tinnitus affected by using earphone (MLR, p < 0.01) after controlled by working period. It can be concluded that prevalence of NIHL and tinitus are relatively high, NIHL affected by using hearing protection and earphone while tinnitus affected by using earphone. It is recommended for workers to use hearing protection in noise workplace and to reduce using earphone while PT DPS must provide hearing protection and do briefi ng to increase workers’ awareness about using hearing protection.
