A campaigner and a representaive from the company go head-to-head
Campaigners against plans for a wind farm in east Berkshire have said they believe the noise of the turbines will disrupt their sleeping patterns.
Opponents believe the five turbines planned for next to the M4 in Rushy Mead are too close to homes.
Partnerships for Renewables (PfR) has said the farm would power 5,500 homes and it is consulting with residents.
About 150 people attended a meeting held by Householders Against Rushy Mead (Harm) at Arborfield British Legion.
The group had invited sleep expert Dr Chris Hanning to address the meeting.
Jan Heard, from Harm, who lives about 350m (985ft) from the proposed site, said: "We have worries that the noise from these turbines will cause sleep deprivation.
"We are not against wind farms, but not this close to where people are living."
PfR has said it would fund and operate the site which is on land owned by the University of Reading.
The firm and the university have said they will continue to consult the local community about the plans.
A PfR spokesperson said: "Currently the testing is continuing and only once the results of these are known would a planning application be submitted.
"The development of the site will only take place if the local conditions are right - PfR are still assessing these."
The original plan for six turbines was scaled back after British Aerospace feared they could adversely impact the radar at Heathrow.
