Get set, go

The difficulties encountered when designing a stadium sound system are similar to those encountered by churches, halls and nightclubs. Problems are compounded however by extensive use of concrete and steel, as well as large open spaces. Planning a PA system to deliver clean sound throughout the Waitakere Stadium was aided by the use of computer-aided design.

It's notoriously difficult to design PA systems for stadiums, says Grant Kirton, managing director of The PA People.

The PA People have extensive experience designing large scale audio systems, including some of New Zealand's biggest projects such as Jade Stadium, Hawkes Bay Stadium, Yarrow Stadium in New Plymouth, Rotorua's International Stadium, Blenheim Stadium and the Waitakere Stadium.

"A lot of work must be completed before equipment is installed. It's imperative to minimise the effects of reverb, caused by sound colliding against hard surfaces, and maximise any acoustic properties of the space," says Kirton.

The company made extensive use of 3D computer modelling to map the sound qualities of the stadium rooms. This enabled numerous designs to be considered before any expenditure was incurred.

A computerised replica was created, and given to the developers long before construction began.

"The ability to accurately predict a sound system's performance in the stadium, before it is installed, saves a lot of time and trouble when working with clients nationwide," says Kirton.

Component consideration resulted in the selection of EV horn-loaded speakers, which helped overcome the density of the space.
