About This Item
IEEE 656-1985 is a technical standard for measuring audible noise from overhead transmission lines, providing a consistent basis for evaluating sound emissions in power system applications. It is relevant where transmission line performance must be assessed in relation to nearby communities, operating conditions, and environmental expectations. By defining a common measurement approach, IEEE 656-1985 helps support more reliable comparison of results and clearer engineering decisions in overhead line planning, testing, and review.
Overview of IEEE 656-1985
This standard focuses on the measurement of audible noise associated with overhead transmission lines, a practical concern in power, energy, and related industrial applications. IEEE 656-1985 is intended to bring consistency to how noise levels are assessed so that engineers and technical reviewers can compare findings with greater confidence. In utility and transmission engineering work, that consistency can help inform line design choices, operational assessments, and documentation tied to acoustic performance.
Typical use cases
IEEE 656-1985 is commonly used when evaluating overhead transmission lines during design studies, field measurements, or noise-related compliance reviews. It may support utility engineers, consulting teams, and testing personnel working on transmission corridors near residential, commercial, or sensitive land-use areas. The standard is also useful when comparing alternative line configurations, reviewing operating impacts, or documenting audible noise characteristics for project planning and technical reporting.
Why it matters
Accurate audible-noise measurement is important because it affects design control, community impact assessment, and the consistency of engineering decisions. IEEE 656-1985 helps reduce uncertainty by giving teams a defined reference for measuring sound from overhead lines rather than relying on informal methods. For procurement, design review, and testing workflows, that can improve comparability between projects and support more defensible conclusions about performance and risk. As a superseded standard, it may also be relevant for legacy documentation and historical reference.
