WHO Guidelines for Community Noise (hospital wards)

World Health OrganizationLatest · 1999 (guidelines for community noise)

Scope

WHO's community-noise guidelines recommend sound-level thresholds for hospital patient rooms, widely cited in acoustic-design work. Actual hospital noise routinely exceeds these levels; the guidelines set the target, not the norm.

Where it applies in the room

  • Patient room acoustic design
  • Alarm sound-level calibration

Key requirements at a glance

Daytime target≤ 35 dB(A) in patient rooms during the day.
Nighttime target≤ 30 dB(A) at night, with peaks ≤ 40 dB(A).
