Acoustic Emissions of Semi-Permeable Trailing Edge Serrations

The trailing edge of a NACA 0018 airfoil is modified through the attachment of serrations with different degrees of permeability. Acoustic beamforming is used to inspect the turbulent boundary layer-trailing edge noise emissions from the unmodified and serrated trailing edges. Different freestream velocities and angles of attack are investigated. The serration permeability is ...

Buy Quiet as a Means of Reducing Workplace Noise

Machinery supplied within the European Economic Area must comply with the noise requirements of Machinery Directive 2006/42/EC. Machine manufacturers must reduce noise to the lowest level achievable and provide noise emission data so people can use their products without risk from noise. Declared noise emissions should help purchasers and users identify low or lower noise machinery ...

Measuring the Risk of Impulsive Noise at Work: One Practitioner’s Tips

There is a risk of immediate damage to hearing from short duration, high-level impulsive sounds that are typically perceived as “bangs”. These sounds may arise from impact action tools, weaponry, and explosive events. The risk is normally associated with the instantaneous peak sound pressure level. Reliable measurement of these high-peak sound pressure levels can be challenging, ...

The Development and Use of Tools to Support Workplace Hand-Arm Vibration Exposure Evaluation

Long-term exposure to hand-arm vibration (HAV) from powered machinery is known to be responsible for damage to the hand and arm. To protect workers, employers are required to apply appropriate measures to control vibration exposures. A key part of the process of effective assessment and control of vibration risks is the evaluation of vibration exposures. The vibration data required ...

The Efficacy of Anti-vibration Gloves

Anyone seeking to control the risks from vibration transmitted to the hands and arms may contemplate the use of anti-vibration gloves. To make an informed decision about any type of personal protective equipment, it is necessary to have performance data that allow the degree of protection to be estimated. The information provided with an anti-vibration glove may not be easy to ...
