Improvements in education, technical support, and regulatory enforcement reduce barriers to implementation of engineered noise control
The most effective intervention—engineered noise controls (ENC) —is rarely implemented; a qualitative study was designed to investigate barriers to the implementation of ENC. Many factors emerged as possible barriers to the implementation of engineered noise control, including: poor knowledge of relevant regulations, noise reduction options and the health impacts of noise; weak technical skills and experience; low ranking of noise as a hazard by stakeholders; issues around job insecurity, weak language skills; lack of ‘quiet’ machine options and information from equipment...
Noise induced hearing loss – Audio demonstration by the Health and Safety Executive, UK
Noise induced hearing loss is irreversible damage to the ears caused by exposure to high levels of noise. A recording on HSE site demonstrates how hearing is gradually lost over a working life: « Noise induced hearing loss – Audio demonstration reveals potential effects». You can also 'see' the sort of damage that excessive noise can cause inside your ears; the clip has been reproduced from "The Hearing Video" by the kind permission of WorksafeBC.

Support and determination to get accustomed to hearing protector use are important factors in hearing conservation for musicians.
Despite a high level of sound exposure and a fairly large selection of earplugs available, musicians have often been reported to use personal hearing protectors only seldom. Musicians reported that earplugs hampered listening to their own and their colleagues' playing; earplugs affected either timbre or dynamics, or both. Additionally, several reasons related to discomfort of use were itemized. The research therefore tested subjects. With the REAT procedure, the values obtained in sound field were relatively close to the manufacturer's nominal specifications. Then, subjects were tested...
Health and safety culture have the greatest influence in controlling noise risks: cultural changes could generate the most improvements!
What factors influence employers' decisions and practices? Three factors were found to influence noise management: (i) managers' own knowledge/awareness of noise risks and associated controls, (ii) the health and safety culture of the company and (iii) its size. Managers generally underestimated the significance of noise as an occupational health risk; a critical knowledge gap was understanding what controls exist and would work in practice. The size of the company influenced the approach taken with smaller companies showing increased likelihood of reduced quality in noise management (ie...
