Noise and cooling from an electric vehicle charging hub

The noise objection to a charging hub comes from the transformer and the cooling fans, not the cars. Here is how BS 4142 treats tonal plant and which mitigation earns its place.

Smoke control areas and solid fuel stoves

A stove can be lawful to install and unlawful to burn ordinary wood in. The Clean Air Act rules and the planning rules are separate regimes with separate tests.

Night-time noise, LOAEL and SOAEL in planning decisions

The Noise Policy Statement for England deliberately sets no numeric threshold, so any figure you adopt is a professional judgement that has to be justified as one.

Noise from nurseries and school playgrounds

Play noise is intermittent, intelligible and judged subjectively. An absolute assessment at the nearest windows plus a conditionable management regime beats a rating level.

Rooftop plant noise assessed to BS 4142

A BS 4142 assessment turns on the rating level at the nearest receptor against the background sound level in the same period. Source data and geometry decide the answer.

Air source heat pump noise in a domestic garden

A garden heat pump avoids a planning application only if the calculated sound level at the nearest neighbouring habitable window stays within the limit. Here is how siting decides that, and what the options are when it does not.

Lighting and bats: applying the ILP and BCT guidance

A lighting scheme on a site with bats is a licensing document as well as a design. This covers spectral output, optical control, curfews, dark corridors and what a reviewer should expect to see.

When odour modelling is needed and what it involves

Most odour cases are settled on screening and a specified abatement system. Here is when dispersion modelling is warranted, and what it costs in time and evidence.

BS 4142 rating level and acoustic feature corrections

Rating level equals specific sound level plus character corrections. Most review failures come from the corrections and from how the background level was chosen.

Clay shooting ground noise: how it is assessed

A shotgun report lasts milliseconds and travels much further than a continuous source of the same loudness. Shooting ground applications turn on event levels, frequency of use and conditions.

Tonal and impulsive corrections in a BS 4142 assessment

BS 4142 allows up to +6 dB for tonality, +9 dB for impulsivity and +3 dB for intermittency. Each rests on a judgement, and that judgement is what reviewers attack.

Ventilation strategy where windows cannot be opened

Where external noise means windows stay closed at night, ventilation and overheating both have to work without them. One shared assumptions register keeps the acoustic and thermal models describing the same building.

Rooftop plant screening and what it does for noise

A visual screen around rooftop plant is not an acoustic barrier unless it is imperforate, heavy enough, sealed and tall enough to break the sight line to the right receiver. Here is how to get that on the drawings.

Kennels and dog day care: assessing barking noise

Barking is impulsive, unpredictable and loudest at the worst times. Assessing it properly, and offering controls before being asked, is what separates a permission from a refusal.

Anaerobic digestion plant noise and odour together

An anaerobic digestion application usually fails on the combination of engine noise and feedstock odour rather than on either alone. Scoping both from the same operational description is what holds it together.

Car park noise at night: doors, alarms and reversing

Car park complaints are about single events, not averages. Here is how to characterise night-time door slams and alarms, what design fixes them, and which conditions hold up.

Noise conditions on a takeaway: hours, deliveries and plant

Hot food takeaways are sui generis, so the permission is where councils control noise. Which sources they can condition, what the plant limit really demands, and how to vary a condition later.

How to read a noise assessment before you object

Most weaknesses in a submitted acoustic report show up in the survey summary, the measurement location plan and the comparison table. Here is how a resident can find them inside a 21 day consultation period.

Vibration effects near a railway at planning stage

For housing beside a railway the reradiated noise criterion usually drives the structural design. How the assessment works, what to measure, and where barriers are useless.

Wind turbine noise assessment for a small rural scheme

ETSU-R-97 and the Institute of Acoustics good practice guide still govern wind turbine noise in England. For a small scheme the simplified route can remove a monitoring campaign entirely.

Light nuisance objections: what counts and where to complain

A floodlight shining into a bedroom is usually an environmental health matter, not a planning one. How the two systems divide, what evidence helps, and which conditions actually control light.

Sports pitch floodlighting and curfew conditions

Floodlighting applications turn on spill and hours. The documents that settle them are an iso-illuminance plot, an aiming schedule and a condition that controls lighting hours, use hours and the timer.

EV charging as air quality mitigation in planning

Most charge points offered as air quality mitigation are already required by Part S. What the baseline is, how to specify passive provision that works, and where charging sits in the mitigation hierarchy.
