Background: Twenty-two million workers are exposed to hazardous noise in the United States. The purpose of this study is to estimate the prevalence of hearing loss among U.S. industries. Methods: We examined 2000-2008 audiograms for male and female workers ages 18-65, who had higher occupational noise exposures than the general population. Prevalence and adjusted prevalence ratios (PRs) for heari
Norfolk, Virginia 23501. Dear Senator Warner:. Thank you for your letter of June 3, 1982, on behalf of your constituent, Mr. Taylor L. Grizzard, President of the Virginia Processors Association, concerning the Occupational Safety and Health Administrations (OSHA) hearing conservation amendment to the occupational noise exposure standard.. In recent public hearings, OSHA received testimony from the National Broiler Council, and the Agency has also received numerous comments and letters from poultry slaughtering and processing companies. We are pleased to receive their comments and we have entered them into the public record of the noise standard and the hearing conservation amendment. OSHA staff members will take these comments into consideration as they draft the final decisions on certain elements of the standard.. With respect to the problem of the U.S. Department of Agricultures (USDA) requirement for non-absorbent (and therefore reflective) surfaces, we feel that there is no regulatory ...

... (Occupational Noise Exposure Database) is a noise exposure calculator and database manager all in one. One*dB supports traditional assessment methods such as dosimetry, but it is specifically designed for the sound exposure profiling method, also known as T-BEAM (Task-Based Exposure Assessment Modeling). This method of noise exposure assessment compiles individual sound samples measured for primary job activities that a worker performs. These activities, along with their associated sound levels, are entered into One*dB to compute the overall 8-hour TWA.. Results of worker risk assessment audits using this software can be used to direct the other elements of the hearing loss prevention process. They are repeatable from one audit to the next permitting development of audit trend charts showing progress in the noise control program and reductions in worker-at-risk statistics.. As part of the HearSaf software suite, One*dB handles the noise exposure records needed to document exposures and ...
Hearing screening should be conducted in a clinical or natural environment that is conducive to obtaining reliable screening results and that is free from auditory and visual distractions and interruptions. In addition, the location should allow for privacy and confidentiality.. Perform daily listening checks to rule out defects in major pure-tone screening components. Ambient noise levels may exceed ANSI standards for pure-tone threshold testing in audiometric test rooms (ANSI, 2013) but must be sufficiently low to allow accurate screening. A sound level meter, if available, may be used to establish maximum permissible noise levels at 25 dB HL for the earphone to be used during screening (i.e., supra-aural or insert earphones). However, when a sound level meter is not available, a biologic check is suitable.. ...

The few studies evaluating the changes caused by cigarette smoking on hearing loss induced by occupational exposure to noise have reached discordant conclusions. The aim of this study is to investigate the interactions between cigarette smoking and occupational exposure to noise as risk factors in the onset and development of hearing loss. The study was performed on a sample of 557 shipyard workers exposed to noise at an Equivalent Level (Leq) of 93 dBA. On the basis of their smoking habits, they were divided into three groups: group (A), non-smokers; group (B), smokers (15-30 cigarettes per day); and group (C), heavy smokers (over 30 cigarettes per day). The study focussed on the audiometric responses of the subjects at the frequencies of 500, 1000, 2000, 3000 and 4000 Hz. The results were then compared using statistical techniquees (Internal correlation coefficient, exponential model, ANCOVA, NPC test). Comparison of the audiometric responses showed statistically significant differences between the

Generally, a measure of the noise level in an environment or from a sound source. For a point in an environment, the quantity is sound pressure level in decibels (dB). For a sound source, the quantity is sound power level in either decibels (dB) or bels (B). Either of these quantities may be stated in terms of individual frequency bands or as an overall A-weighted value. Sound output typically is quantified by sound pressure (dBA) or sound power (dB). Densely populated data and communications equipment centers may cause annoyance, affect performance, interfere with communications, or even run the risk of exceeding OSHA noise limits (and thus potentially cause hearing damage), and reference should be made to the appropriate OSHA regulations and guidelines (OSHA 1996). European occupational noise limits are more stringent than OSHAs and are mandated in EC Directive 2003/ 10/EC (European Council 2003). ...

Using a multi-cellular, pathway model approach, we investigate the Drosophila sp. segmental differentiation networks stability as a function of initial conditions. While this networks functionality has been investigated in the absence of noise, this is the first work to specifically investigate how natural systems respond to random errors or nosie. Our findings agree with earlier results that the overall network is robust in the absence of noise. However, when one includes random initial perturbations in intracellular protein WG levels, the robustness of the system decreases dramatically. The effect of noise on the system is not linear, and appears to level out at high noise levels.
About 22 million workers are exposed annually to hazardous levels of occupational noise. The Labor Department is soliciting pitches for innovative ideas.
An improved method and apparatus for forming nonwoven webs by spinning filaments into a quench chamber where they are contacted with a quenching fluid, then utilizing the quench fluid to draw the filaments through a two-dimensional nozzle spanning the full machine width, and collecting the filaments as a web on a porous surface. In contrast with the prior art, low motive fluid pressures can be used, and a non-eductive drawing means utilized to minimize air turbulence and the resulting filament entanglement in the drawing means while maintaining substantially constant cross machine filament distribution. The apparatus and process reduce problems relating to filament breakage and spreading and result in increased productivity and improved web formation. Other advantages include the ability to continuously spin highly pigmented polymer filaments and reduced hazards associates with high noise levels.

SCR keeps putting out releases at high speed. In the usual DVD-box comes the usual black disc with the (usual?) dark ambient/ industrial/ noise soundscapes. Axone we know from earlier releases. They contributed two long tracks go from tranquil soundscapes via tranquil to harder industrial and noise. kNOw is a new act to me. They contributed four tracks, which start with strange soundscapes and extreme rhythmical noise. The other two tracks are more ambient soundscapes, quite monotous, but dark. Again quite a nice release on SCR, but I hope the next releases will have a bit more variety in style. The noise tracks of kNOw are for example something that I would like to hear more of. ...
Danny Devos (DDV) is an influential Belgium artist, known for his performances and sculptural installations. The keynotes in his work is crime and murder. In the 80s he started researching criminals and serial killers. Since then he upholds an intimate and far-reaching correspondence with a number of serial killers. Quite a lot of his work does relate to this research. In 1981 Danny Devos and Anne Mie van Kerckhoven started noiseband Club Moral. This research of years of existential borders has led to an impressive ouvre which correspond with the theme of the Haperende Mens: Danny Devos with his exhausting performances, installations about psychological terror and his profound industrial noise music is looking for confrontations with his audience and is trying to let them feel the borders of the power of endurance.
