Noise impact assessments for planning applications, EIAR and infrastructure projects across Ireland and the UK. Allegro Acoustics delivers baseline noise surveys, predictive noise modelling, construction and operational noise assessment, mitigation design and clear technical reporting for planning authorities.
We establish the existing noise environment, predict noise from the proposed development and assess the impact at nearby noise-sensitive receptors against the criteria relevant to the project.
We provide noise impact assessments for planning applications, EIAR submissions and infrastructure projects, from the baseline survey through to modelling, mitigation and reporting.
Establishing the existing acoustic environment at representative noise-sensitive receptors, using Class 1 instrumentation across representative daytime, evening and night-time periods, with meteorological conditions logged throughout. This work draws on the same capability behind our environmental noise monitoring service.
Three-dimensional predictive modelling of the proposed development, including buildings, terrain, screening and plant sound power data, calculated at every receptor of interest, so design and mitigation options can be tested before construction begins. Our guide to noise modelling and noise mapping explains how the models are built and validated.
Noise and vibration chapters for developments requiring an Environmental Impact Assessment Report, covering baseline conditions, assessment methodology, construction and operational effects assessed separately against different criteria, cumulative effects where relevant, mitigation and residual effects, with monitoring or verification commitments where appropriate.
Acoustic reports for planning applications, technical clarification for planning and design teams, and responses to Requests for Further Information, including on schemes we did not originally assess.
We review the proposed development, plant and activities, likely noise sources, nearby receptors, the planning context and the assessment methodology that applies.
Where required, we carry out representative baseline monitoring at the receptors that matter, using Class 1 instrumentation across representative time periods.
We predict construction and/or operational noise using 3D acoustic modelling and assess the results against the criteria relevant to the project.
Where levels are at risk of exceeding the applicable criteria, we test practical mitigation in the model and prepare the technical report or EIAR chapter, carrying engineered treatment through into industrial noise control design where required.
Allegro Acoustics has successfully delivered noise impact assessments for major infrastructure, data centre, life sciences and renewable energy developments.
Field measurement and noise impact assessment supporting the planning process for a nationally significant electricity transmission project.
Baseline survey and 3D noise modelling supporting the mitigation strategy for a city centre data centre development.
Baseline monitoring and predictive modelling supporting planning applications for an existing solar development and a proposed extension.
A noise impact assessment may be required where noise could be a material planning consideration, for example, where a development introduces significant new noise sources near existing noise-sensitive receptors, or introduces new noise-sensitive development close to existing sources. The requirement depends on the nature of the development, its location, planning policy and the planning authority's requirements.
A noise impact assessment typically includes a baseline noise survey to establish the existing acoustic environment, predictive noise modelling of the proposed development, assessment of the results against the criteria relevant to the project, mitigation design where levels are at risk of exceeding those criteria, and a technical report suitable for submission to the planning authority.
Not every application requires one. Whether a baseline noise survey is needed depends on the nature of the development, its proximity to noise-sensitive receptors, local development plan policy and the specific requirements of the planning authority. Where noise is likely to be a material consideration, commissioning the survey early avoids delay later in the process.
A standalone assessment answers the noise question for a planning application. An EIAR noise and vibration chapter sits inside a wider Environmental Impact Assessment Report, describes the receiving environment, assesses construction and operational phases separately against a stated methodology, and states the residual impact after mitigation.
Yes. Allegro Acoustics can respond to noise-related Requests for Further Information, including where the original assessment was prepared by another consultant. This may involve additional baseline monitoring, clarification of the assessment methodology, further modelling or more detailed mitigation design.
