Nine months of pregnancy puts the expectant mother on alert mode as she
works to nourish her child during the period. Some maternity specialists claim that the baby
can start reacting to various sounds as early as 5 to 6 months. Still, it pays
to know what the fetus actually hears while inside the mother’s tummy.
Fetuses start developing audio perception capabilities at 20 weeks old,
with the ears completing its structural development in 24 weeks. Studies have
shown that an environment with a sound level quieter than 70 decibels is optimal
for the baby’s relaxation and eases the mother’s stress. However, sudden loud
noises, such as a slamming door or a nearby explosion, may trigger strenuous
movements in the child. At the same time, the internal sounds in the body, such
as the mother’s heartbeat, may seem too loud for him or her.
The voices of the parents, on the other hand, help provide a calming
effect on the fetus. Even if the baby cannot actually recognize words, the tone
and speech patterns create the positive effect on him or her. Some
pediatricians claim that a lack of aural stimulation hampers certain elements
of the baby’s development; thus, the importance of the mother striking a
balance between nurturing in a secure environment and going out to experience
natural surroundings and talking to the baby about them.
