Electricity transmission infrastructure

Acoustic engineering for national infrastructure

Allegro Acoustics supports utilities, network operators and their design teams to manage noise risk on the assets that keep the country running, from transmission and substations to water and wastewater infrastructure.

Noise risk on infrastructure that cannot be switched off

Utility assets are long-lived, highly visible and operate close to communities. Noise is one of the most common grounds for objection and complaint.

Planning and consenting risk

Infrastructure projects attract scrutiny. Noise and vibration assessment that stands up to An Bord Pleanala and third party review protects the consent programme.

Community complaints

Transformers, pumps and standby plant generate tonal noise that carries. Complaints are costly to resolve after commissioning and easier to design out beforehand.

Live operational constraints

Utility assets rarely come offline. Surveys, modelling and any physical noise control must be delivered around continuous operation and strict access control.

Long asset lifecycles

Decisions taken at design stage govern noise performance for decades. Getting the acoustic criteria right early avoids expensive retrofit later.

How we support utilities

Planning and EIAR support

Baseline noise surveys, predictive modelling and the noise and vibration chapters of Environmental Impact Assessment Reports, prepared to withstand scrutiny during consenting.

Substation and transmission noise

Assessment and control of transformer tonal noise, cooling plant and switchgear, including compliance against planning conditions and community noise limits.

Water and wastewater assets

Noise assessment and control for pumping stations, treatment works, blowers and standby generation, where plant frequently sits close to residential boundaries.

Design, supply and installation

Where a noise problem needs solving rather than reporting, we design, supply and install the acoustic solution and verify it in place. Silencers, enclosures, barriers and damping, delivered on live sites.

Why utilities teams choose us

We work on live networks

Our engineers are used to operational constraints, permit systems and access control on energy and utility sites, so surveys happen without disrupting supply.

We solve, not just report

Where a problem needs fixing, we design, supply and install the solution and verify it works. Few consultancies carry that capability, and it removes the gap between advice and outcome.

Evidence that withstands scrutiny

Infrastructure consents attract objection and review. Our assessments are prepared to be defensible in front of regulators, planners and third party experts.

Planning a school project?

Get us involved early. We’ll review your design, identify acoustic risks and ensure you pass completion testing first time, on budget and on programme.
