Noise levels generated by construction, infrastructure and industrial activities can have a significant impact on nearby communities and surrounding environments. Accurate monitoring is essential to ensure projects remain compliant with environmental regulations and minimise disruption to residents and businesses.
Excessive noise can interfere with sleep, heighten stress levels and, in more serious cases, lead to physical health issues. Under the Control of Pollution Act 1974 in the UK, local authorities have the power to restrict construction activities and issue fines where noise levels are deemed unacceptable. The time of day is a crucial factor in how noise is assessed and whether it constitutes a statutory nuisance. While it is not reasonable to expect construction sites or industrial areas to operate in complete silence, it is equally unfair for residents to be subjected to disruptive noise, particularly during night-time hours.
Construction firms dedicate considerable time and resources to reducing the impact of their operations on neighbouring properties and the wider community. However, despite thorough planning and best practice measures, certain activities may still result in unintended disturbance.
Contractors are frequently measured against Key Performance Indicators, and effective noise management plays an important role in meeting these standards. Proactively undertaking surveys, implementing continuous monitoring and applying appropriate mitigation measures demonstrates responsibility and due diligence. Clear, reliable records not only support positive community relations but also provide robust evidence of compliance and professional conduct.
Remote environmental noise monitoring equipment has become increasingly portable and readily available in recent years. However, effective environmental noise monitoring is not simply a case of placing a device on site. It requires the correct specification of equipment for the specific application, along with appropriate calibration, positioning and data interpretation. Remote Datum regularly installs noise monitoring systems alongside multi point vibration monitoring equipment, particularly during piling, demolition or other high impact works taking place close to residential properties or noise sensitive environments such as schools, hospitals and commercial premises.
Under the Control of Pollution Act 1974, local authorities have the authority to impose conditions on how construction activities are carried out, including permitted working hours, noise limits and methods of operation. In addition, noise generated from construction sites, vehicles, plant or machinery in the street may be classified as a statutory nuisance under Part III of the Environmental Protection Act 1990.
While compliance with a consent issued under the Control of Pollution Act can provide a defence against statutory nuisance proceedings brought by a local authority, it does not automatically prevent action being taken following a complaint from a private individual. In such cases, an abatement notice may still be served. However, it remains a valid defence to demonstrate that the ‘best practicable means’ were employed to prevent or minimise the impact of the nuisance.
Remote Datum Ltd can supply robust, reliable equipment for the long term measurement and reporting of environmental noise, providing accurate data to support compliance, protect community relations and demonstrate responsible site management.

PPG 24 (Planning Policy Guidance 24) was issued to assist local authorities in England in limiting the adverse effects of noise through the effective use of planning powers. It sets out the key factors that should be considered when determining planning applications for noise sensitive developments, as well as proposals that may introduce new noise sources.
The guidance explains how the planning system can be applied to manage environmental noise in a balanced and proportionate way, seeking to protect amenity without imposing unnecessary restrictions on development or creating undue financial and administrative burdens.
PPG 24 introduces the concept of Noise Exposure Categories for residential schemes, providing a framework for assessing acceptable levels of exposure from different noise sources such as road, rail or industrial activity. It also recommends suitable mitigation measures and planning conditions to help minimise potential impacts, ensuring that both existing communities and new developments are appropriately protected.
Road traffic noise levels are assessed and forecast using the Calculation of Road Traffic Noise guidance, commonly referred to as CRTN. This established methodology provides a structured framework for both measuring existing traffic noise and predicting future noise levels based on traffic data.
Originally published by the Department of Transport in 1988, the Calculation of Road Traffic Noise (CRTN) serves as a central reference document, setting out a consistent and standardised approach to road traffic noise assessment across the UK. It outlines procedures for on site monitoring and explains how noise levels can be predicted using traffic flow information and other relevant variables.
Noise predictions under CRTN take into account a range of influencing factors, including traffic volume, vehicle speed, the proportion of heavy goods vehicles, road surface type, gradient, distance from the carriageway and the presence of screening or reflective surfaces. By incorporating these elements, the methodology provides a reliable basis for assessing potential impacts on nearby residential or sensitive receptors, supporting planning applications, mitigation strategies and long term environmental noise management.
Prediction of noise levels includes factors such as:
Disturbance from noisy neighbours, persistently barking dogs or loud entertainment venues can quickly lead to tension within communities. Ongoing or excessive noise from nearby properties is often a source of frustration, stress and anxiety. In many cases, those responsible are unaware that they are causing disruption, and a simple conversation can resolve the matter amicably.
However, where informal resolution is not possible, a statutory notice may be served requiring the individual or organisation responsible to reduce or stop the nuisance. Failure to comply can result in further enforcement action or legal proceedings. In such situations, it is essential that noise levels have been properly monitored and accurately recorded, providing clear, defensible evidence to support any action taken.
Across both the European Union and the UK, a range of regulations and directives have been introduced to assess, map and control noise exposure. Noise is generally categorised into three main types: occupational noise experienced in the workplace; neighbour or neighbourhood noise arising from domestic or local activities; and environmental or ambient noise generated by transport networks, industrial operations and other external sources.
Responsibility for managing these different types of noise varies. The Health and Safety Executive oversees occupational noise and provides guidance to help employers determine and maintain safe exposure levels for employees. Local authorities are typically responsible for addressing nuisance noise from residential properties, businesses and construction sites. Where noise is deemed to constitute a statutory nuisance, councils have the authority to investigate complaints and take appropriate enforcement action to protect affected residents.
