As a rule of thumb, babies should not be exposed to noise levels over 60 decibels. The noise level recommended for hospital nurseries is actually lower, at 50 dB. For reference, a quiet conversation is between 50 and 55 dB and an alarm clock is 80 dB.
This is at least 115 decibels (dB), according to Oregon pediatric audiologists Heather Durham, Au. D., and Shelby Atwill, Au. D. Alarmingly, sounds over 80 dB for an extended period of time are damaging and anything greater than 100 dB for even a few minutes can cause permanent noise-induced hearing loss (NIHL).
While 60 to 70 decibels is great for keeping calm babies calm, when your baby is upset, you'll want to increase the white noise volume to match the intensity of your little one's wailing—which can reach 100 decibels or more!
Safe sound levels vary based on the duration of exposure. In general, noises softer than 80 dB will not damage hearing unless the exposure lasts for several hours. The amount of time an infant is exposed to sound is important.
Sound can travel through your body and reach your baby. Very loud noises may be able to damage your baby's hearing. Ear plugs or earmuffs do not protect your baby's hearing. If you're pregnant the only way to protect your baby's hearing is to stay away from loud noise.

"Certainly a child's scream right in the ear can be very loud," said Anne Oyler, an audiologist at the American Speech-Language-Hearing Association in Rockville, Maryland, who has also not treated Barnard. "Generally, a baby's cry can be about 130 decibels," she said.
Your child's inner ears may be damaged if they are around extremely loud noises, or around loud noises for long periods of time. Noise-induced hearing loss happens slowly and is painless. Once the hearing nerve is destroyed, it is permanent.
80 decibels is fairly loud. It's equivalent to the noise of a busy downtown street. Being loud, it is a noise level that may harm your hearing if you are exposed to it for longer periods (more than 8-10 hours/day).
It's tempting to keep the white noise going through the night, but it's really not recommended. "Operate the infant sound machine for a short duration of time," Schneeberg advises. She recommends using a timer or shutting it off once your baby is asleep, provided you're still awake.
White noise reduces the risk of SIDS.
We DO know that white noise reduces active sleep (which is the sleep state where SIDS is most likely to occur).
Vacuuming is a great task to do while babywearing because it doesn't require a lot of bending over or intense movements that could wake your little one from their slumber.
SIDS is most common at 2-4 months of age when the cardiorespiratory system of all infants is in rapid transition and therefore unstable. So, all infants in this age range are at risk for dysfunction of neurological control of breathing.
Signs of hearing loss in your baby can include: Not being startled by loud sounds. Not turning toward a sound after he's 6 months old. Not saying single words like “mama” or “dada” by the time he's 1 year old.
Babies and young children have thinner skulls and smaller ear canals than adults. That means that they are at greater risk of getting hearing damage from a loud sound than adults are. Some experts say that a child's ears are likely to perceive sound up to 20% louder than an adult's.
Even everyday noises in your home or neighborhood that are fine for you are too loud for your baby. For example, a vacuum cleaner runs at 70 dB, and a city street can get up 90 dB.
A normal conversation: 60-70 dB. Open office noise: 65-75 dB. An alarm clock: 70-80 dB. Washing machine: 70 dB.
Short-term exposure to loud noises can result in temporary hearing loss and ringing in the ears. Exposure to loud sounds throughout childhood can cause permanent hearing loss as well as harm a child's physical and psychological health – including learning, behaviour, speech and language.
A good rule of thumb is, if you can talk easily over the sound, it shouldn't harm your baby's hearing . Your baby is also more sensitive to pitch. High-pitched noises may bother her more than they would you .
Infants and young children are more sensitive to loud noises than adults are. Because the ear canal is smaller in children, the sound pressure that is generated in the ears is greater compared to adults. In other words, loud sounds are even louder for kids.
A crying child can expose caregivers and health care providers to sound pressures as high as 120 dB(A), merely 10 dB(A) less than the intensity of noise from an airplane departure. Continuous exposure to this amplitude may cause auditory discomfort, ear pressure, mild pain, and even tinnitus.
The sound of a baby crying can reach 120 dB (close to the noise intensity of a departing plane). Noise-reducing earplugs can help to offer protection for your ears (and your sanity).
While it's considered taboo and pacifying to 'shush' someone when they're older, for babies the 'shush' is the best natural calming method. In combination with a tight, wrapped and swaddled body, a slow or more rapid rocking motion, a pacifier or nipple, the shushing sound really gets your new baby into dreamland.
