We all need a favourable signal-to-noise ratio to hear well in noise. But did you know that it is particularly important for children? Children don’t hear as well as adults do when there is background noise in the listening environment.

In a typical, noisy classroom, the signal-to-noise ratio will vary from + 5 to – 7 dB. At a 0 dB signal-to-noise ratio, speech intelligibility is about 60% for 6-7-year-olds with normal hearing.
