Chronicle of a deaf audiologist

Children are more susceptible to noise than adults!

Classrooms can be noisy! Classroom noise levels are expressed as signal-to-noise ratio (SNR), which compares the level of the signal (teacher’s voice) to the level of noise. A typical, noisy classroom will vary in SNR from + 5 to – 7 dB.  Research showed that at 0 dB SNR, adults and older children, when compared to 6-7-year-olds, showed speech intelligibility scores of approximately 80% and 60%, respectively.

At what age does a child’s ability to hear in noise approach an adult? And why is there a difference between adults and children? Watch the video 😊
