Locals living near Dublin Airport say they can't sleep at night due to the noise from the North Runway.
Over 200 people attended a public meeting on Monday night.
The meeting was the third held in the last few months, after the runway opened last August.
Changes were made to flightpaths in February - however residents claim it has made no difference.
Barry Whyte was there and spoke to residents for The Pat Kenny Show.
Irene told him she can't sleep.
"It's very bad, it wakes me up at night," she said.
"The planes fly directly over my house just when I'm trying to fall back to sleep again.
"It's like thunder happening, and it's been very constant during the day.
"If you're outside at all you have to stop sometimes, if you're talking to people, because it is so loud.
"The windows are all closed in the house, but still, I can hear it inside.
"It's very stressful, it's very disturbing and it's very difficult to even concentrate on what you're doing".
'We can't talk to people'
Michael, who runs a garden centre, said his business has been impacted.
"We're an outdoor business - we can't talk to people when a plane is going overhead," he said.
"We can't take phone calls when planes are going overhead because of the noise level.
"We have to tell the customer: 'Hold on please a minute' and no sooner have we finished with that one and another one comes".
Over 200 people turned out in North County Dublin last night over residents concerns about the noise of low flying aircraft from the new Dublin Airport North Runway.

Michael said he estimates there are planes flying overhead "every two minutes, so that is unbearable."
This has been very bad … particularly when they said they were going to improve [the situation] on the 23rd of February.
"This actually got worse and weekends are very poor - on Saturday we can't hear ourselves in the garden centre".
Angela's father is in a local nursing home with advanced dementia.
"A lot of the time now with the low-flying planes, it's so loud up there," she said.
"When you're in his room you have to keep the windows closed, but it still doesn't shut out the noise.
"Yesterday there was two planes, one after another... he got a little bit agitated.
"He was like, 'Is that noise going to come in here?' - and we're like, 'No, it's fine'.
"If he's like that, what about the other residents? It's them you think of too," she added.
Dublin Airport operator DAA said some areas are being overflown at higher altitudes.
"The revised flightpaths that came into effect on February 23rd has resulted in aligning these more closely with the information previously communicated by DAA.
"Some areas like St Margaret’s, Shallon and The Ward Cross will continue to be overflown as anticipated, whilst other areas like Oldtown and Ballyboughal will also continue to be overflown but at higher altitudes".
The operator said while other areas - such as Skephubble, Kilsallaghan and Rolestown - will no longer be directly overflown, they will still be exposed to a certain amount of aviation noise.
It added that 18 new noise monitoring terminals are also being added to the existing system.
