Identification of SOAEL and LOAEL in Support of the NPSE - NO0236

Description
The Noise Policy Statement for England (NPSE) sets out the long term vision of Government noise policy for the effective management and control of noise from environmental, neighbour and neighbourhood sources within the context of sustainable development. The aims of the policy are to: avoid significant adverse impacts on health and quality of life; mitigate and minimise adverse impacts on health and quality of life; and where possible, contribute to the improvement of health and quality of life.
Objective
The objective of this project is to establish, where possible, threshold levels for the Lowest Observed Adverse Effect Level (LOAEL) and the Significant Observed Adverse Effect Level (SOAEL) for a range of noise source/effects based on strong scientific evidence.

There are 5 project phases:

1. Literature Review, including Email survey of international contacts:
To provide the scientific evidence that underpins the development of appropriate threshold levels for the LOAELs and SOAELs. The project team have already access to much of the existing material but an email survey to relevant international experts in the field will capture any emerging evidence.

2. Synthesis of relevant research, standards and other guidance:
To identify the optimum exposure-response relationships for the various effects based on the evidence from phase 1 and the development of criteria to define what constitutes a significant adverse impact.

3. Identification of LOAELs and SOAELs:
To identify LOAELs and SOAELs for ten situations to include noise from environmental (road, rail, air), neighbour (noise inside/outside homes) and neighbourhood (industrial, amplified music) sources and their effects on health and well being (annoyance, sleep disturbance, cognitive learning and cardiovascular etc)

4. Case study demonstration:
To provide a case study based on real data to demonstrate the application of the methodology.

5. Reports and presentations:
To provide Interim Report on progress, a Final Report together with presentations, no more than two, to Stakeholders.
The results from this research will support Defra‟s responsibility for managing noise in England by demonstrating a consistent framework for assessing the impact of noise on health and well being that is applicable for use in planning, land-use development and the protection of the environment.
