Auckland Council has revealed that "screams of delight" from children using a flying fox at a playground exceeded allowable noise levels by 16 decibels.
The equipment at Playtime Park at the base of Mt Wellington next to the Stonefields estate has been disabled after tests at various times of the day over several days in December.
According to the city's district plan, the maximum noise level allowed in residential areas ranges from 40 to 75 decibels depending on time and day.
Noise levels can be exceeded by intermittent noise from normal household activities, like mowing the lawn (about 90 decibels), at reasonable times.
A normal conversation is about 60 decibels, and a car horn around 110.
