| THE LEGISLATIVE OR REGULATORY FRAMEWORK
| |
| Please list all relevant laws, enactment's, standards etc. (where possible giving information how they interrelate) |
Noise insulation grants for new railway works are assessed under the Noise Insulation Regulations 1995 (SI no. XXXX) made under Section xx of the Control of Pollution Act 1974. The details of noise insulation provided is specified under xxxx Regulations 19yy (SI no. xxxx). Entitlement is assessed by reference to 'Calculation of Railway Noise' Dept. of Transport,1996 which provides a method to calculate the noise levels. |

NOISE LIMITS (where stated)
|
|
| What noise limits are used ? Please give details of these in terms of how and where they are specified metric used day and night limits |
The statutory limits for entitlement to a noise insulation grant are: daytime 68 LAeq, 18hr night-time 63 LAeq, 6hr Noise limits apply at 1m from the facade of qualifying internal rooms |
| Is the assessment of noise against the limits based on measurement, prediction or both ? |
Predictions |
| DERIVATION OF NOISE LIMITS
|
|
| Please give summary details on the basis of these noise limits e.g. on which research findings *1 and/or practical considerations |
The basis for the noise limits was agreed by the Mitchell Committee (reported in Railway noise and the insulation of dwellings, DoT, 1991). The Department of Transport then made changes x and y for reasons a and b to the final version.
The aim was to treat railway noise and road traffic noise the same in terms of the degree of community annoyance at which a noise insulation grant scheme could be expected. The committee considered:
- results of surveys of railway noise annoyance (refs x, y and z)
- comparisons between road and rail noise annoyance (refs x, y and z)
- sleep disturbance studies (refs x, y and z)

| Is further research planned or considered necessary ? |
None identified at present |
