Why Kids' Ears Need Quiet Time, Says Hearing Expert
Mainz – September 11, 2026 -- Constant background noise from white noise machines, audiobooks and headphones may be overwhelming children's hearing, according to Eberhard Schmidt, a certified hearing acoustician and president of Germany's Bundesinnung der Hörakustiker (biha).
Schmidt, who also specializes in pediatric hearing care, says ears are always "on" and cannot simply switch off. The real risk comes from a combination of high volume, close proximity to sound sources, and nonstop exposure -- not from sound itself.
Hearing develops before birth, around the fifth month of pregnancy
Unborn babies can perceive sound starting around the fifth month of pregnancy, Schmidt explains. While amniotic fluid and tissue reduce volume, loud repeated noise -- such as at concerts or noisy workplaces -- can still reach the fetus and should be limited during pregnancy.
