What the AAP's 2023 policy statement on noise actually says

Published 2026-05-18 · 9 min read

Informational reference, not medical advice. The American Academy of Pediatrics policy statement is the authoritative source. This page paraphrases and links to it; for clinical decisions consult your pediatrician.

In November 2023 the American Academy of Pediatrics published a policy statement titled Preventing Excessive Noise Exposure in Infants, Children, and Adolescents (Balk SJ, Bochner RE, et al., Pediatrics 2023; 152(5): e2023063752), with a companion technical report. It is much broader than its 1997 predecessor, covering noise exposure from the fetus through adolescence. It is the clinical reference most often cited alongside the 50 dB and 7 ft figures that circulate in parenting media, though, as this page explains, those specific numbers are not stated in the AAP document itself. This page summarises what the statement actually contains, what it does not say, and where the popular figures actually come from.

The headline takeaway: the AAP does not prohibit infant sound machines. On sound machines specifically, the statement is brief. It advises pediatricians to counsel families on safe use, and notes that if devices are used it is safer to place them as far from the infant as possible, keep the volume as low as possible, and limit the duration of use. That guidance sits inside a much larger document about noise as an under-recognised pediatric health risk.

Scope of the 2023 statement

The statement covers three audiences and three exposure contexts. The audiences are the fetus during pregnancy, the newborn in the neonatal intensive care unit (NICU), and the healthy infant at home. The exposure contexts are maternal occupational and environmental noise during pregnancy, NICU acoustic environments, and post-discharge home noise including consumer sound machines.

On the fetal side, the AAP cites evidence that maternal exposure to occupational noise above 85 dB during pregnancy is associated with increased risk of hearing loss in the offspring. It recommends that pregnant individuals in noisy workplaces use hearing protection, and that obstetric clinicians screen for occupational noise during prenatal visits. This portion of the statement gets relatively little attention in consumer coverage but is the most clinically actionable for working pregnant patients.

On the NICU side, the statement reinforces an existing AAP recommendation that ambient NICU noise be kept below 45 dB averaged hourly, with peak levels not exceeding 65 dB. It cites NIOSH occupational exposure data as the baseline and applies a conservative scaling for the vulnerable neonate. NICU staff, incubator manufacturers, and unit designers are the primary audience for this section.

What the statement actually says about sound machines

The sound machine passage is short. The statement notes that pediatricians can counsel families on safe use, that some studies show potential benefits from infant sleep machines, and that one study (Hugh 2014) raised concern about the sound levels these devices can reach. Its safe-use advice is qualitative: if a device is used, locate it as far from the infant as possible, set the volume as low as possible, and limit the duration of use. From that, practitioners and consumer publishers derived three practical rules:

  1. Place the machine as far from the baby as practical. The AAP advises maximum practical distance. The 7 ft figure is a consumer rounding of the distances tested in the Hugh study, rooted in the inverse-square law: doubling distance roughly quarters sound intensity. See the dedicated 7 ft placement page.
  2. Keep the volume as low as possible. The AAP states this qualitatively; it does not give a decibel number. The widely quoted 50 dB target is the recommended noise limit for infants in hospital nurseries, which sits well below NIOSH adult exposure limits. It is detailed in the 50 dB ceiling page.
  3. Avoid maximum volume and limit duration. This reflects the Hugh 2014 audiology study (the Hugh 2014 explainer), which found that three of fourteen consumer machines exceeded 85 dB at maximum setting at 30 cm. The statement cites that study and advises limiting how long machines run. A sleep timer or fade-out is the common practical implementation: see all-night vs sleep timer.

This guidance applies equally to dedicated sound machines, smart speaker routines, white noise apps on a phone, fans used for masking, and any other acoustic source. What matters is the sound reaching the baby's head, not the technology generating it.

What changed from the 1997 statement

The 1997 statement, also published in Pediatrics, was titled Noise: A Hazard for the Fetus and Newborn and covered fetal exposure and the NICU environment. It did not address consumer sound machines, which were not yet a widespread household item. The 1997 NICU recommendations (the <45 dB hourly average) survive into the 2023 update largely unchanged.

Three things are new in 2023. First, the statement broadens its scope from the fetus and newborn to children and adolescents, and addresses consumer sound machines for the first time, citing the Hugh 2014 study and advising safe use (place far away, volume low, limit duration) rather than setting decibel or distance numbers. Second, the 2023 update folds in updated WHO guidance on safe listening levels (notably the Make Listening Safe initiative) and the CDC framing of 70 dB as a long-term-exposure caution threshold. Third, it gives far more attention to recreational and personal-audio noise (headphones, concerts, devices) across childhood and adolescence.

The 2023 statement is also more explicit about climate and environmental noise as background context. It notes the increasing prevalence of urban transportation noise, the spread of consumer audio technology into infant care contexts, and the under-recognition of noise as a modifiable pediatric health risk factor.

What the statement does not say

Three areas where readers commonly extrapolate beyond the statement deserve flagging.

The statement does not recommend a specific brand, model, or sound colour. There is no AAP-approved sound machine list. The recommendations are about output level and placement, not product certification. Marketing claims of “AAP-approved” or “pediatrician-endorsed” without specific dB measurements at the listed distance are not grounded in the policy statement.

The statement does not say that white noise machines cause hearing damage or developmental delay. It says that improper use, particularly at high volume or close placement, presents a plausible risk based on the available measurement studies and on extrapolation from adult occupational data. There is no published cohort study showing documented harm from properly-used infant sound machines, and the AAP does not claim otherwise.

The statement does not provide a hard age at which sound machine use should stop. The 2023 update implies (but does not mandate) that the same safety thresholds continue to apply through infancy and toddlerhood, with progressive relaxation as the cochlea matures. Practical age-related guidance is laid out in safe volume by age.

How the statement is being applied in practice

In practice, the statement matters most as the authoritative reference parents and clinicians point to when discussing safe sound machine use. Several infant-marketed devices now ship with low-volume presets or per-device dB guidance, and the broad direction of the consumer market since 2014 has been toward lower default outputs, in line with the concerns the AAP and the Hugh study raised.

For families, the practical takeaway is simple and unchanged by the wording details: keep the machine well away from the cot, keep the volume low, and do not run it at full output. The decibel target most often cited (50 dB or below) is a sensible conservative ceiling drawn from the hospital-nursery noise limit, even though the AAP statement itself frames its advice qualitatively rather than as a fixed number.

Frequently asked

Where can I read the full statement?

The statement is published in Pediatrics, the AAP’s peer-reviewed journal. Look for ‘Preventing Excessive Noise Exposure in Infants, Children, and Adolescents’, Pediatrics 2023, volume 152, issue 5. The journal’s landing page is at publications.aap.org/pediatrics. AAP members and many institutional subscriptions provide full-text access.

Is the statement legally binding on manufacturers?

No. AAP policy statements are clinical guidance, not regulations. They influence manufacturer behaviour through professional consensus and consumer expectation rather than through enforcement. The U.S. Consumer Product Safety Commission has not adopted a binding decibel standard for infant sound machines.

Does the AAP recommend any specific sound colour?

No. The statement is colour-agnostic. Its safe-use advice (distance, low volume, limited duration) applies equally to white, pink, brown, and other colours. See the colour deep-dives for the spectrum-specific arguments.

Has the statement been updated since 2023?

As of June 2026, the 2023 statement is the current AAP policy. Subsidiary clinical reports may revise individual points; check publications.aap.org for the latest.
