Construction noise levels, frequencies and standards-exceedance incidents
Measurement answer
What this metric measures
Reports construction-related noise measurements against baseline conditions and counts incidents in which noise exceeds established standards.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. EH.A2.1 specifies a reportable structured family: average noise levels and frequencies before and during construction, measured on-site and near sensitive habitats, plus incidents exceeding standards. It is distinct from vessel radiated-noise spectra and from generic noise-management disclosures.
Verified sources
Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Interpretation boundaries
Method disclosures required
Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).
- State the baseline and construction measurement periods and the key daily periods measured.
- Identify measurement locations on-site and near sensitive habitats.
- Disclose the applicable established standard used to determine exceedance incidents.
- State whether the reported frequency is an acoustic-frequency measurement and identify the measurement method.
Record-specific limitations
- The source specifies comparisons between baseline and construction conditions; results should not be interpreted as a full-life-cycle noise assessment.
- The source does not define a single universal applicable standard, so the standard used for determining exceedances must be identified.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
