Posted on 28 November, 2012 at 4:50

Ever wanted to measure the noise pollution in your class or are curious by the sounds of the nearby construction? Using a decibel meter permits students to measure and record sound waves of various noises. Used typically in Sciences, Creative and Performing Arts, TAS and ICT a decibel meter enables students to understand the concept of decibels. This is of particular importance in these KLAs for OH&S purposes as well as learning about the relationships that exist between amplitude and energy. Additionally, decibel meters encourage the use using literacy and numeracy in each of its activity. The new DER laptops have Audacity and Data Harvest EasySense Softwares preinstalled on them permitting students to record and develop their recordings. Decibel meters range in cost and begin from $35. There are also a range of Apps (free and paid) available via itunes and Google Play that work in conjunction with the decibel meter that enable students to continue with their work outside of the classroom.
