This presentation explored how certain aspects of sound are experienced similarly, regardless of a person’s hearing level, and particularly now that digital hearing-devices can be mapped to a wearer’s specific hearing-levels.
Sound fields were also discussed – but classrooms are rapidly altering.
Digital Acoustics For Learning Spaces
Digital tools were shared, for students and educators in a learning group (or space) to optimise their personal and environmental sound – remembering that classrooms are moving away from traditional rows of desks and chairs.
For instance… will children who wear gaming goggles for gamified education have sound-gear, too? Or, will they work off their personal hearing-devices?
Trying the Oculus Rift headset at the MissionV stand at the event was a real insight into using ears-only for communication, with eyes locked onto the headset’s 3D views, that swiveled as heads turned to the left or right.
Too Noisy – A Sound Level App
Educators have recommended the Too Noisy app for school communities to gauge sound in their vicinity. Sound levels in a noise-treated classroom or library can clock at 45 decibels (dB), but rapidly skyrocket to 85dB or more, in a dining area or assembly hall where sound bounces off hard surfaces.
Containing Potential Noise Damage
Too Noisy gives a visual monitor of noise in a physical space, with exposure to 85dB of sound for 8 hours, known to lead to temporary hearing loss. As noise levels in shared spaces rises, say to 115dB at a sports event, an individual’s hearing may be damaged by this noise in less than a minute.
Educator – And Student Awareness
Separate figures from the US show almost 12 per cent of children aged 6 to 19, have noise-induced hearing loss from blasting music via their iPods – and this damage is cumulative as the years pass.
Educators need noise awareness – and knowledge of emerging digital tools to manage sound levels in physical spaces, wherever they practise.
