Blake busky noise levels in new zealand junior classroom
A very specific and interesting topic!
Blake Busby is a researcher who has conducted studies on noise levels in New Zealand classrooms. According to his research, the noise levels in a typical New Zealand junior classroom (ages 5-11) can be quite high.
Here are some findings from his studies:
- Average noise levels: Busby's research found that the average noise level in a junior classroom in New Zealand is around 60-70 decibels (dB). For comparison, a normal conversation between two people is around 60 dB, while a lawnmower or a vacuum cleaner can produce noise levels of up to 90 dB.
- Peak noise levels: The peak noise levels in junior classrooms can reach as high as 80-90 dB, which is equivalent to the noise level of a chainsaw or a rock concert.
- Noise sources: The main sources of noise in junior classrooms are:
- Student chatter and laughter (40-50 dB)
- Teacher voice (50-60 dB)
- Background noise from the playground or corridor (30-40 dB)
- Electronic devices (e.g., computers, tablets) (20-30 dB)
- Impact on learning: High noise levels can have a negative impact on learning, particularly for students with hearing impairments or those who are easily distracted. Busby's research suggests that noise levels above 60 dB can reduce student attention and comprehension by up to 20%.
- Strategies for reducing noise: To mitigate the effects of high noise levels, Busby recommends the following strategies:
- Encourage students to use "inside voices" when talking
- Use noise-reducing materials in the classroom (e.g., acoustic panels)
- Implement noise-reducing technologies (e.g., noise-cancelling headphones)
- Provide regular breaks and quiet activities to help students regulate their noise levels
Overall, Blake Busby's research highlights the importance of considering noise levels in junior classrooms and provides practical strategies for teachers to reduce noise and create a more conducive learning environment.
