Noise Impact Assessment

BS 4142, BS 8233, and ProPG noise screening for planning applications

1. Assessment Type

BS 4142 assesses noise generated by a development; BS 8233 assesses impact on residential; ProPG for residential near transport infrastructure.

2. Noise Source Details

Reference noise level from source (e.g. 85 dB for heavy industry)

Distance at which source level is measured (typically 1m)

Character penalties applied per BS 4142 (+2 dB each, +3 dB for low frequency)

3. Receptor Details

Horizontal distance from noise source to receiver

4. Background Noise Levels

LA90 background levels used for BS 4142 assessment. LA90 is the noise level exceeded for 90% of the time period.

Typical suburban: 45–50 dB

Typical suburban: 35–40 dB

5. Assessment Time Period

7. Mitigation Measures (select all proposed)
