The impact of noise

Direct influence: Ear damage, causes hearing loss, reduces the hearing threshold.

Indirect influence: Psychology, cognition, ability to learn, read, comprehend long-term memory, and focus attention.

A lot of high-intensity sounds can knock out the memory-protecting mechanisms. It causes permanent damage to the structure of the baby’s ears and sound systems. Repeated lingering noises also cause permanent damage.

Signs of hearing impairment

Older baby

Noises below 70 – 80 dB are safe. The level of 80 dB is about the level of a tinkling noise at a morning noodle shop in Hanoi or the sound of traffic on Thanh Thai street at 3 pm. The level of 60 dB (very safe) is the equivalent of near-private talk.
