Key questions

The evolution of wind farm technology over the past decade has greatly reduced noise from wind turbines, with the main sound being the aerodynamic swoosh of the blades passing the tower. There are strict guidelines in the planning regulations on wind turbines noise emissions to ensure the protection of residential amenity. A comprehensive noise monitoring regime will be undertaken to ensure the proposed development complies with regulations.

As part of the planning process, Tullacondra Green Energy will ensure the project is constructed and operated to minimise noise. We will conduct extensive tests during the planning process to demonstrate that the proposed turbines will not exceed legislated noise levels. During the site optimisation process the wind turbine layout will be designed so that noise levels at nearby residential properties are not in breach of national planning guidelines. The World Health Organisation has published its Environmental Noise Guidelines for the European Region in which recommendations are made for wind turbine noise. The recommended level of noise produced should be below 45 dB (A). The current guidelines in Ireland and the UK, which are in line with international best practice, are set at between 35 and 45-dB(A) dependent on the time of day and background noise. For reference, a fridge typically produces a sound level of 32–47 dB(A).

The potential for the proposed development to impact on aviation and radar assets was assessed. No impacts on any aviation interests is predicted.

As part of the EIA process, consultation was undertaken with bodies that are responsible for managing and maintaining telecommunications networks. No impacts on any telecommunications assets were identified.

Shadow flicker refers to when the blades of a wind turbine pass between the sun and the observer, planning guidelines require that any effects of shadow flicker be mitigated by installing solar sensors on the turbine which automatically shut down the turbine during times of possible shadow flicker.
