Pupils engi­neer a vic­tory

Auckland City Harbour News - - NEWS -

A group of in­ner city stu­dents may have a so­lu­tion to cut­ting out the noise of heavy traf­fic next to their school.

Free­mans Bay School won a ju­nior merit prize at the Trans­power Neigh­bour­hood Engi­neer Awards for its project Lis­ten Up.

The an­nual com­pe­ti­tion part­ners schools with engi­neers and tech­nol­o­gists who work with stu­dents on de­vel­op­ing their ideas.

More than 40

en­tries were re­ceived from across the coun­try in­clud­ing a junk­yard golf course, an alarm for deaf stu­dents that was re­ported in Auck­land City Har­bour News last month and a school scooter park­ing sys­tem.

Stu­dents at Free­mans Bay set out to im­prove their class­room en­vi­ron­ment by min­imis­ing the im­pact of traf­fic noise from the Wellington St mo­tor­way on-ramp be­side their school.

Af­ter brain­storm­ing ideas the young team found old clothes, bed- ding and blan­kets put in file boxes and at­tached to walls made for a qui­eter class­room.

An­dre Cowan, from Mar­shall Day Acous­tics, says mount­ing ab­sorp­tive ma­te­ri­als on the walls re­duced the re­ver­ber­a­tion time from 1 to 0.6 sec­onds.

The rec­om­mended re­ver­ber­a­tion time for a pri­mary school class­room is be­tween 0.4 to 0.5 sec­onds, he says.

The school was pre­sented with its award and $750 last week.
