They were giving evidence in Alexandra before the Central Otago District Council's hearing panel.
Highlands Motorsport Park Trust has applied to the council to vary one of its resource consent conditions so it can hold a race meeting at Easter on the same day as the neighbouring Central Motor Speedway.
That is banned under its current consent.
Highlands wanted to stage races on the Saturday and Sunday of Easter (April 19 and 20) and is limited to racing between 8am and 6pm, while the speedway planned to race on Good Friday and from 4pm on Easter Sunday.
Ten submitters supported the application and the same number opposed it, while one submitter was neutral.
The hearings panel has reserved its decision.
Zoe Wood, of Bannockburn Rd, wanted to outline the ''human factor'' of being one of the closest neighbours of the motorsport park.
The noise during race days was so upsetting that her family had to leave their home.
''I stress that I'm not against the motorsport park, I can see the benefit for the community ... I just wish it was someone else's neighbour, not mine.''
Alan McKay lived within 150-200m of the motorsport park and a similar distance from the speedway track.
He tended to leave his home on race days, driven out by the ''excessive noise''.
Although most of the activity was permitted, excessive noise for 15 hours or more on combined racing days would be unacceptable, he said.
Jack Searle, of Bannockburn, said the council should have permanent noise monitoring at various sites in and around Cromwell.
Other opponents agreed and said noise from both venues was so loud they could not hold conversations outside their homes during races.
Environmental acoustic specialist Malcolm Hunt, of Wellington, said noise levels recorded during racing at Highlands in January were below permitted levels.
The noise effect of speedway and motorsport park racing on one day at Easter would not be ''unreasonable'', he said.
Highlands general manager Mike Sentch said Easter racing was designed to support Warbirds over Wanaka and would benefit the Central Otago economy.
He thought a day of ''double-racing'' in return for a ''no-racing'' day would balance each other out.
Highlands lawyer Phil Page said it was clear the opponents disliked racing noise and Highlands knew it had an obligation to mitigate noise -''and we'll continue to do the best we can to manage that''.
However, it was entitled to hold racing on 16 days a year. If it was allowed to race on Easter Saturday and Sunday, it would not race on Good Friday or Easter Monday, he said.
