Acoustic requirements and design review

Define the criteria before choosing the solution

We start with project objectives, affected locations and the responsibilities of the parties involved. Source parameters are distinguished from environmental noise requirements so that the specification does not confuse different quantities. Relevant operating conditions, supplier information needs and the application of criteria to equipment, installations or the complete facility are then defined for the planned investment.

Available designs and alternatives are reviewed against the requirements, source information and consistency of assumptions across documents. We identify missing data, contradictions and matters for designers or suppliers to clarify. This supports comparison on a common basis and checks whether conditions for later verification have been considered, rather than relying only on a general statement of compliance.

The review is based on the submitted documentation and does not automatically verify the performance of a future installation. Changes to the design or equipment information may require another review. Supply and installation of noise controls are excluded; the service organises requirements and highlights risks and questions worth resolving before procurement or construction proceeds.

Technical data

Subject Acoustic criteria for a design, specification or proposed alternatives.
Service type Requirement definition and expert review of design documentation.
Assessment basis and requirements Investor objectives, location conditions, equipment data, design documents and relevant assessment criteria.
Method
  1. Distinguish requirements for noise sources and receiver locations.
  2. Define reference conditions and information required from suppliers.
  3. Review designs and compare alternatives against agreed criteria.
  4. Document comments and conditions for subsequent performance checks.

What you receive

You receive requirements for the design or specification and a review report. The material presents criteria, their application conditions and comments on the documents reviewed, including questions requiring answers. It supports discussions with designers and suppliers and preparation for future performance checks, without including supply or installation of noise controls.

Scope and limitations

Supply and installation of noise control measures excluded

Strategic noise mapping

Connect spatial and acoustic information at a strategic scale

Strategic mapping requires a consistent basis for multiple datasets. We define the area, sources and reference period, then review terrain, buildings, traffic and exposure information. Data completeness and spatial consistency are checked so that local gaps or different update dates do not become hidden assumptions affecting the entire assessment of a city or infrastructure network.

We prepare model inputs, assign source parameters and carry out calculations within the agreed scope. Results are converted into maps and summaries showing spatial differences in the acoustic situation. Data origins and significant methodological decisions are documented, explaining how assumptions about traffic, buildings and assessment periods influence the resulting picture of noise exposure.

A strategic assessment does not replace investigation of an individual event or a short-term measurement addressing a particular complaint. Results represent the map's reference conditions and depend on input quality. We identify limitations and matters relevant to future updates, supporting selection of areas for closer assessment and preparation of a subsequent action programme.

Technical data

Subject Spatial noise and exposure patterns across cities or infrastructure networks.
Service type Strategic noise mapping supported by GIS data analysis.
Assessment basis and requirements Commissioned scope, applicable strategic mapping requirements and spatial, traffic and exposure information.
Method
  1. Define the mapping area, sources and reference period.
  2. Check and prepare spatial information and traffic datasets.
  3. Model noise and derive spatial distributions of results.
  4. Prepare maps, summaries and documentation of the methodology.
Delivery model KFB Enviro

What you receive

You receive a strategic noise map and supporting report describing data, methods, findings and limitations. Map and summary coverage follows the agreed assignment. The material provides an organised basis for interpreting exposure, planning actions and future updates, while maintaining the distinction between strategic assessment and local noise problem investigation.

Periodic environmental noise measurements

Noise results connected to actual operating conditions

A sound level alone does not explain what happened during a survey. We review sources, operating periods and the surroundings before agreeing suitable measurement positions and survey conditions. Planning also considers site access and whether noise from the assessed activity can be distinguished from other sounds present in the surrounding area.

During the survey, we document relevant facility or infrastructure operating conditions, the measurement setting and circumstances affecting interpretation. Results are processed for the agreed assessment periods and compared with applicable criteria where relevant. The report therefore explains both the numerical findings and the basis for comparison, making clear which operating conditions the evidence represents.

The assessment describes the observed situation rather than every possible operating mode. Where intermittent events, background sound or the representativeness of the campaign affect the conclusions, we explain their significance. This helps you decide whether the next step should be an additional survey, targeted source diagnosis or a longer period of monitoring.

Technical data

Subject Environmental noise from a facility or infrastructure asset.
Service type Periodic field measurements of environmental noise.
Assessment basis and requirements Survey purpose, site documentation, the identified measurement obligation and a field method appropriate to the source.
Method
  1. Agree operating conditions, measurement positions and assessment periods.
  2. Measure noise and document relevant surrounding conditions.
  3. Process results and evaluate the influence of background sound.
  4. Compare findings with criteria and explain assessment limitations.
Delivery model KFB Enviro

What you receive

You receive a measurement report and assessment of results, covering survey locations, conditions, methodology and conclusions against the agreed purpose. The document distinguishes tested operating conditions from situations requiring further observation, supporting future measurement planning and informed management of the facility's environmental noise impact.
