New $125,000 noise monitoring system at speedway
Auckland City is monitoring speedway noise with a new $125,000, remote controlled monitoring system at Western Springs
Stadium – the first of its kind in New Zealand.
The system represents the latest technology and can monitor noise 24 hours a day, seven days a week.
The new 5m-tall device is equipped with a weatherproof microphone and noise-level analyser. It also records wind speed
and direction – essential information for noise control enforcement because weather conditions have a significant impact
on noise levels.
All data is then securely transmitted in real-time to an Auckland City computer where it can be analysed by a noise
The data can also be viewed, in real-time, by the speedway's promoter, helping it to identify when noise levels are high
and respond accordingly.
The device can also record the actual noise, as a digital audio file (MP3), which can be referred to later to help
determine what caused the noise.
''This state of the art tool represents a significant step forward in addressing concerns about speedway noise in the
area. This new technology will make monitoring easier, and more accurate. It is like having a noise specialist on site
24-seven,'' says Auckland City Environment’s Group Manager, Barry Smedts.
The Western Springs speedway has been an integral part of Auckland for 76 years. The stadium hosts a maximum of three
practice sessions, 20 races, and six concerts each year.
The first speedway practice for this season started on 16 October 2004.
