Yes, loud shouting can negatively affect a baby, causing emotional distress, impacting brain development, potentially damaging hearing from prolonged exposure, and creating an insecure environment that hinders attachment and regulation skills, even if they don't understand words, as they sense the threatening tone. For infants, consistent yelling can make them tune out voices, while during pregnancy, extreme noise can affect the developing fetus.
Your child's inner ears may be damaged if they are around extremely loud noises, or around loud noises for long periods of time. This is called noise-induced hearing loss.
Short-term loud noise exposure. The baby is protected by amniotic fluid and other tissues, meaning the eardrum and middle ear of the developing fetus cannot amplify sounds as they usually would, making anything the baby hears muffled. Sounds that might be perceived as loud to the mother will be less loud for the baby.
Sounds from outside the body are lower inside the womb, but not completely silenced. Avoid areas that are louder than 115 dBA during pregnancy, even if you are wearing hearing protection. Avoid low frequency sounds (noises you feel as a rumble or vibration).
Research says that intense anger might put you at a higher risk for placental abruption, which is rare but can mean your baby doesn't get all the oxygen and nutrients it needs during pregnancy. Studies also show that if you are more angry during pregnancy, your baby may have growth delays and sleep issues.
In a follow-up across pregnancy, the fetuses of the high-anger women were noted to be more active and to experience growth delays. The high-anger mothers' high prenatal cortisol and adrenaline and low dopamine and serotonin levels were mimicked by their neonates' high cortisol and low dopamine levels.
Studies have shown that infants as young as one month-old sense when a parent is depressed or angry and are affected by the parent's mood.
Plus, it's noisy inside your uterus – sounds from your breathing, heartbeat, and digestion are as loud to your baby as a washing machine. That said, your baby will hear your voice more clearly than all others. That's because the sound of your voice reverberates through your body when you speak.
Don't eat undercooked meat, poultry or eggs
Babies experience immediate stress responses when exposed to yelling, including increased heart rate, elevated cortisol levels, heightened startle reflexes, and difficulty sleeping or feeding.
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions every 3 minutes, lasting 2 minutes each (or 1 minute long for some variations), for over 1 hour. It helps differentiate true labor from false labor (Braxton Hicks), signaling it's time to head to the birthing center, while subsequent pregnancies often follow the faster 5-1-1 rule.
First trimester
It is also the trimester of 'mood swings' brought on by pregnancy symptoms. One minute you are feeling so happy and the next you are fuelled with doubt, worry or sadness. It can be quite confronting having those feelings of sadness, worry and fear when all you wanted was to be pregnant.
This can lead to: Emotional Distress: Even if they don't understand the words, the tone and volume can scare them. Developmental Issues: Chronic exposure to yelling can affect a baby's emotional and cognitive development. Parent-Child Bond: Yelling can damage the trust and bond between you and your baby.

Key Takeaways. It's best to skip concerts and very loud music while pregnant, since loud noise can cause stress in babies while they're in the womb. One concert isn't going to hurt your baby, but very loud or repeated noise exposure may cause pregnancy complications.
DANGER SIGNS DURING PREGNANCY
One approach is the 'ten day rule,' which states that "whenever possible, one should confine the radiological examination of the lower abdomen and pelvis to the 10-day interval following the onset of menstruation."
Do avoid exposure to pesticides, lead, and mercury. Don't smoke or vape tobacco or marijuana, drink alcohol, or use illegal drugs during your pregnancy. If you face addiction or substance use challenges, tell your pregnancy health provider. They can help you to quit and connect you to support groups.
Common signs your baby is in distress in the womb include heart rate irregularities, decreased fetal movement, intense cramping (in the mother), vaginal bleeding (in the mother), excess or insufficient weight gain, abnormal levels of amniotic fluid, and other well-recognized symptoms.
Exposure to a 90 dB sound level for a few minutes won't cause harm, but if a two-hour movie averages 90 dB and you take your baby to the movies on a regular basis, hearing loss may develop over time. Worse still, very loud sounds that exceed 130 dB can cause an instantaneous loss of hearing.
Scientific studies show they'll move around less in the womb and have a slower heartbeat when they hear their mum's voice. This is why, from the moment they're born, babies prefer the sound of their mother's voice to one they've never heard.
Babies are very aware of any friction between the people around them. Arguments and upsets are not good for your baby's brain development, both before and after they are born. It makes it harder for them to feel safe and secure and build strong bonds.
There can be great variations among healthy babies as to how often and how hard they "kick." Kicking includes all types of movements. Research shows girls kick as often as boys. Babies who kick a lot in the womb are also more active after birth. Some mothers have more trouble feeling the kicks than others.
Emotional Memory and Its Long-term Effects
So, while they might not specifically remember a shouting incident, the negativity can linger. In particular, infants who experience repeated instances of angry yelling may experience psychological effects like1: Problems attaching to their caregiver.
