HEARING AND NOISE IN SOUND AVIATION

•Active noise reduction headsets. This type of headset uses active noise reduction technology that allows the manipulation of sound and signal waves to reduce noise, improve signal-to-noise . ratios, and enhance sound quality. Active noise reduction provides effective protection against low-frequency noise. The electronic coupling of a low-

the Noise Reduction Rating (NRR) The NRR describes the average sound level reduction (attenuation) provided by a hearing protection device (HPD) in a laboratory test. Since the NRR is based on laboratory testing, it does not take into account the loss of protection that occurs when hearing protectors

CODE OF PRACTICE MANAGING NOISE AT WORKPLACES

(c) adoption of a systematic approach to reducing and managing exposure to excessive noise; and (d) the reduction and management of exposure to excessive noise through consultation between employer and employees. STRATEGIES 2.3 The most effective way of controlling exposure to workplace noise is through reduction of noise at its source.

Assessing and Mitigating Noise Impacts

When potential adverse noise impacts are identified, the applicant should incorporate noise avoidance and reduction measures in the construction or operating plans. The applicant’s submittal should also assess the effectiveness of proposed mitigation measures in eliminating adverse noise reception.

5. Noise Management - WHO

5. Noise Management The goal of noise management is to maintain low noise exposures, such that human health and well-being are protected. The specific objectives of noise management are to develop criteria for the maximum safe noise exposure levels, and to promote noise assessment and control as part of environmental health programmes.
