Our Services

Engineering-led acoustics, from monitoring to solution

We go beyond measurement. Our five-level service approach takes you from initial monitoring through precise modelling, engineered solutions and regulatory advocacy, solving the right problem, first time.

Beyond measurement. Beyond reports.

Our service ladder takes you from initial monitoring through to engineered solutions and regulatory advocacy.

1

Monitor

Environmental & workplace noise monitoring, baseline surveys, IEL compliance

2

Model

Acoustic modelling & simulation, noise mapping, predictive analysis

3

Design

Engineering solutions, noise control strategy, targeted mitigation design

4

Implement

On-site coordination, commissioning verification, performance validation

5

Advocate

Regulatory support, planning advocacy, expert witness, EPA engagement

Most competitors stop at Level 1. We operate at Levels 3–5. That is our differentiation.

Environmental Noise Monitoring

Environmental noise monitoring for industrial facilities, infrastructure and built environment projects. Services include annual IEL compliance surveys, baseline noise monitoring and noise complaint investigations.

Our engineers deploy Class 1 instrumentation and undertake detailed analysis in accordance with EPA guidance, ISO 1996 and project-specific requirements. We help clients understand the existing acoustic environment, identify dominant noise sources and provide the evidence needed to support compliance, planning and effective decision-making.

Deliverables

  • IEL compliance noise monitoring
  • Baseline environmental noise surveys
  • Long-term continuous monitoring with remote access
  • Weather-correlated data analysis and filtering
  • EPA NG4 and ISO 1996 compliant reporting
  • Source identification and contribution analysis
  • Audit-ready reports

Workplace Noise & Vibration Risk Assessments

Protect your employees and meet your legal obligations under the Safety, Health and Welfare at Work (General Application) Regulations. We deliver comprehensive workplace noise and vibration exposure assessments that identify risk, quantify exposure and provide practical, proportionate control measures.

Our assessments go beyond simple measurement. We map noise sources, identify the dominant contributors and recommend targeted controls that address the actual risk, not generic solutions that cost more than they need to.

Deliverables

  • Personal noise exposure assessments (LEX,8h)
  • Noise mapping and contour plotting
  • Hand-arm and whole-body vibration exposure assessment
  • Source identification and ranking
  • Hearing conservation programme support
  • Practical noise control recommendations
  • Regulatory compliance reporting

Planning Noise Assessments

Secure planning approval first time with robust, defensible noise impact assessments. Allegro Acoustics delivers comprehensive baseline surveys, predictive noise modelling and clear EIAR noise chapters that satisfy planning authority requirements and withstand regulatory scrutiny.

Our team understands what Irish and UK planning authorities expect. We align our methodology with EPA guidance, local development plan policies and An Bord Pleanála requirements ensuring clients can progress their projects with confidence.

Deliverables

  • EIAR Noise & Vibration Chapters
  • Request for Further Information (RFI) Response
  • Baseline environmental noise surveys
  • Predictive noise modelling
  • Construction noise and vibration impact assessment
  • Operational phase noise impact assessment
  • Mitigation design and specification
  • Assessments carried out in line with best practice standards and guidelines.

Industrial Noise Control

Engineered noise control solutions that solve the correct problem first time. Allegro Acoustics uses acoustic modelling to identify the root cause and design targeted interventions that avoid over-engineering and unnecessary capital spend.

From IEL compliance and workplace noise reduction to community noise complaints, our experienced engineers provide a turnkey service from assessment and modelling through to design, installation support and verification. Our practical solutions and extensive live-site experience help clients resolve noise issues quickly and with minimal disruption.

Deliverables

  • Root cause noise source identification
  • Acoustic modelling of existing and proposed scenarios
  • Engineered noise control design (barriers, enclosures, silencers, damping)
  • Specification and procurement support
  • On-site coordination during installation
  • Commissioning verification and performance validation
  • Cost-benefit analysis of noise control options

Building Acoustics

Architectural acoustic design that ensures buildings sound great and are fit for purpose, delivering regulatory compliance alongside an exceptional user experience. Allegro Acoustics works with contractors and design teams from concept through to detailed design, tender, construction and completion, ensuring projects achieve the required acoustic standards and project-specific requirements.

Combining engineering expertise with practical construction knowledge, our team of engineers and architects specify solutions that are buildable, cost-effective and deliver the required acoustic performance.

Deliverables

  • Airborne and impact sound insulation design
  • Reverberation time (RT) design and specification
  • Façade sound insulation assessment and design
  • Plant noise break-out and break-in assessment
  • MVHR and mechanical services noise assessment
  • TGD E & BS 8233 compliance checks
  • Acoustic specification for tender documentation
  • Site inspections
  • Pre-completion and completion acoustic testing (ISO 16283, ISO 3382)
